text: The aging of biodiesel proceeds via multiple pathways, with oligomerization
playing a central role. In this study, we investigated an epoxide-dependent oligomerization
pathway, which had previously only been postulated. Using methyl oleate (C18:1)
as a model monounsaturated fatty acid and acetic acid as a representative, reactive
nucleophile and known biodiesel aging product with a suitable boiling point, oligomeric
products were identified by size-exclusion chromatography (SEC) coupled with electrospray
ionization quadrupole time-of-flight mass spectrometry (ESI-QTOF-MS). The concentration
of 20 wt% was chosen to ensure a measurable kinetic effect while maintaining stable
reaction conditions. Furthermore, the role of methyl oleate during biodiesel aging
was addressed. Time-resolved analysis confirmed the proposed sequential order
of reactions. It was pointed out that elimination reactions may occur. The data
support the formation of epoxides, despite the isobaric overlap with ketones,
and show that hydroxyl intermediates undergo esterification and etherification.
Moreover, experiments with pure C18:1 demonstrated that acetic acid–derived oligomers
are generated. Under Rancimat conditions, addition of 20 wt% acetic acid resulted
in an approximately 1.1 – 2.6 increase in product yield. Kinetic analysis revealed
structure-dependent formation and decay behavior of the aging products, with slightly
faster epoxidation and shifted product distributions toward higher oligomeric
species in the presence of acetic acid. Reactive intermediates were consumed more
rapidly than oligomeric species and all decay processes followed apparent second-order
kinetics. These findings provide direct experimental evidence for the involvement
of epoxide-dependent pathways in biodiesel aging.

text: Solketal and oxymethylene ether (OME) are two promising blending candidates
for regenerative fuels (e-fuels), which could contribute to a holistic solution
to the energy crisis. In this study the thermo-oxidative aging of these two e-fuels
in their pure form as well as in binary mixtures with different ratios (3:1, 1:1,
and 1:3) (vol%) is investigated. Herein, the reaction networks of the thermo-oxidative
aging process of both e-fuels and mixtures thereof is elucidated based on intermediates
and decomposition products determined via GC-MS. Furthermore, changes of important
fuel-specific parameters like kinematic viscosity and density as well as total
acid number during aging have been determined. The 3:1 solketal:OME (vol%) mixture
exhibits a higher stability to thermo-oxidative aging than the pure fuel components
or mixtures with other ratios. The viscosity value of this mixture is within the
DIN EN 590 norm after accelerated aging of 72 h (viscosity (72 h) = 4.25 mm(2)/s))
unlike other blends. The maximum value of the total acid number of this aged mixture
reaches only similar to 29 % of the maximum value of aged pure OME and has the
lowest value of all mixtures. Furthermore, the formation of a precipitate could
be successfully suppressed in the 3:1 solketal:OME (vol%) mixture different from
other mixtures. With these findings, this study contributes to the design of new
sustainable fuels for the transport sector.

text: "The decarbonization of the energy supply is one of the biggest and most important
challenges of the 21st century. This paper contributes to the solution of the
energy crisis by investigating the stability of alcohols as e-fuels. The focus
is on the investigation of the aging mechanism of the linear alcohols 1-hexanol
and 1-octanol compared to the iso-alcohol 2-hexanol. It is analysed in detail
how the time-dependent aging varies depending on the chain length and the position
of the hydroxy-group, both in the liquid and in the gas phase. It is shown that
a variety of aging products such as aldehydes, acids, short-chain alcohols and
esters are formed during the aging of the n-alcohols by oxidation, decarboxylation,
oxidative C-C bond cleavage and esterification. In contrast, the decomposition
of the iso-alcohol is significantly lower. The results show that the total acid
number is significantly higher for aged n-alcohols than for the aged iso-alcohos,
while the kinematic viscosity decreases for all alcohols during aging. Carbon
mass balancing shows that after accelerated aging for 120 hours, around 80% of
the iso-alcohol is still present, compared to only around 57-63% for the n-alcohols.
In addition, significantly fewer acids are formed with the iso-alcohol. In this
study, iso-alcohols have a higher stability against thermo-oxidative aging compared
to n-alcohols, showing their potential as e-fuels. Furthermore, the chain length
of the alcohols has also an influence on aging, as more different aging products
can be formed with increasing chain length.\r\n\r\nThis paper contributes to the
solution of the energy crisis by investigating the stability of alcohols as e-fuels.

text: The energy crisis and dependence on fossil fuels forces societies to develop
alternative pathways to secure energy supplies. Therefore, non‐fossil fuels such
as biofuels and e‐fuels can help counteract the resulting demand for existing
combustion engines. However, biofuels, like biodiesel, have disadvantages in terms
of oxidation stability. In general, aging of biodiesel is a complex mechanism
due to interaction of various components. In order to develop an ideal fuel, the
mechanism must be understood in full detail. In this work, an attempt is made
to simplify the system by using methyl oleate as a biodiesel model component.
In addition, other fuel components of interest such as alcohols and their respective
acids help to clarify the aging mechanism. This work used isopropylidene glycerol
(solketal) as the main alcohol, 1‐octanol and octanoic acid. A holistic biodiesel
aging scheme was developed by using generated data and evaluating the role of
acids. They epoxidize unsaturated fatty acid via Prileschajev reactions. In addition,
the role of epoxides in oligomerization reactions is confirmed. Moreover, the
alcohols show that the suppression of oligomerization can be achieved by the reaction
with methyl oleate. The alcohol‐dependent aging products were determined by quadrupole
time‐of‐flight (Q‐TOF) mass spectrometry.

text: Formulating energy policies at national, European, and global levels is extremely
challenging. The move away from fossil fuels is associated with a variety of technological,
economic, and social implications, each of which is subject to dynamic changes
and societal scrutiny and can hardly be predicted with certainty. Therefore, a
fact-based assessment for the path to a sustainable green energy future is sought
out in this paper, using the road-based mobility sector of the Federal Republic
of Germany as an example. The analysis performed in this paper is built on publicly
accessible, reputable sources like DESTATIS and EUROSTAT. In addition, some very
simple calculations were made, e.g., on the potential for wind and photovoltaic
energy within Germany. Such an analysis needs to start with the overall energy
consumption of any one country. A basic assumption of the paper is that the energy
system of the future will be based to a large extent on electricity and its storage
in chemical energy. It is assumed that, in addition to hydrogen, liquid energy
sources will play a significant role due to the simplicity of their logistics
and the subsequent implications on cost. Examples of green, electricity-based
fuels with great potential are methanol, methane, and ammonia. Additionally, biomass
plays an important role, either for direct use as a fuel or as a source of non-fossil
carbon. Today, biofuels, i.e., biodiesel and bioethanol, deliver the largest contribution
to climate protection in the EU transport sector. The main goal—the reduction
of greenhouse gas emissions—often collides with geopolitical circumstances or
national political necessities. This includes, for example, the current world
market situation and its national impacts caused by the Russian attack on Ukraine.
The prospect for a green, sustainable, and defossilized energy supply are discussed
in this context. The paper concludes that a defossilized world energy supply and
trade based on renewable electricity and its derivatives, eHydrogen and refuels,
and on biomass, is feasible.

text: The complexity of biodiesel aging has shown that the mechanism needs further
research. The rate of aging product formation and associated interactions can
help improve fuel quality. Since biodiesel is a multicomponent system and constant
changes occur in the chemical environment, which interactions yield which products
must be shown in more detail. Particularly under observation was the correlation
between peroxides and epoxides. In addition, it is critical that the influence
and interactions of new drop-in fuel candidates be investigated. In this work,
the kinetics of the formation of aging products of methyl oleate (C18:1) are studied.
The aim was to reduce the complexity in order to be able to make more precise
and detailed statements about the mechanism. Ketones, acids, peroxide, and epoxide
values were recorded. A distinction is made between pure methyl oleate and mixtures
with 3 wt% isopropylidene glycerine (solketal). After solketal decomposed in the
blends, the aging process showed changes. The influence of solketal resulted in
a higher number of acids and epoxides over time. It implied that peroxides are
not necessarily the precursor of epoxides. In summary, correlation and solketal’s
influence showed that a sequence of aging products could be detected.

text: This article contributes to the ongoing dialogue regarding the future application
of renewable e‐fuels as part of a holistic solution to the energy crisis. In order
to be able to continue using internal combustion engines in a sustainable manner,
it must be ensured that these engines are operated exclusively with renewable,
CO2‐neutral fuels. One way to achieve this is the use of
a fluorescence sensor in the vehicle in combination with fuels that are labeled
with a fluorescence marker. This study presents an investigation into the use
of the benzophenoxazine dye Nile red as a fluorescent marker for distinguishing
fossil from renewable fuels. In addition to assessing the stability of the fluorescent
marker against thermo‐oxidative aging, the study probes its antioxidative impact
on fuel aging, by comparing unlabeled and with Nile red labeled aged fuels. Furthermore,
an examination of fuel‐specific parameters underscores the positive effect of
Nile red on fuel stability. A comparison with the antioxidant butylated hydroxytoluene
confirms the antioxidant effect of Nile red.

text: Due to the fact that modern diesel engines require very well-defined fuel
properties to ensure high efficiency, low emissions and a long durability, the
fuel properties and their determination methods have to be standardized. Most
diesel fuel standards allow a certain volume fraction of biodiesel that can be
blended to fossil diesel fuel. Biodiesel consists of saturated and unsaturated
fatty acid methyl esters (FAME) which are more susceptible to oxidation compared
to fossil diesel fuel. Oxidation products formed by autoxidative processes can
lead to higher emissions, a higher corrosiveness, fuel filter blocking, clogging
of fuel injectors, the formation of deposits in the entire fuel system and a decreasing
lubricity [1]. Therefore, oxidation needs to be prevented by the addition of oxidation
inhibitors. These antioxidants are consumed during storage, resulting in partial
loss of their efficiency against oxidative stress. After this induction period
all antioxidants have been consumed and harmful oxidation products can be formed.
For the determination of the long-term storage stability of diesel fuels rapid
oxidation stability test methods were developed and defined by standards. In Europe,
the most important determination methods are the Rancimat method and the rapid
small scale oxidation test (RSSOT). Both methods differ in the construction of
the measurement device and various parameters. However, it is not clear whether
the results of both methods can be correlated in general. Due to the importance
of the oxidation stability, we here describe the results of a literature research
that was carried out using 17 literature sources. Possible correlation factors
between the Rancimat and the RSSOT method were analyzed, showing that a universal
correlation cannot be found. In contrast, a comparison of individual series of
measurement, e.g. with the same antioxidant at various concentrations, can show
a good correlation between the methods.

text: The need for new bio based drop-in components for combustion engine fuels
and the availability of sustainable glycerol from biodiesel production has focused
attention on isopropylidene glycerol (solketal). The present study investigates
the physical and chemical behavior of solketal in ternary blends with diesel fuel/biodiesel.
Hydrotreated vegetable oil (HVO) was used as renewable non-polar aliphatic diesel
fuel substitute in biodiesel/ solketal blends. HVO can be considered a prototype
for other non-polar fuel components such as paraffinic fuel streams from Fischer-Tropsch
or BtL processes. Surface tension, permittivity and aging behavior were analyzed.
Furthermore, the cetane number (CN) and the viscosity was determined. Permittivity
reflects the polarity of blends and their components with its change being an
indicator of loss of physical and chemical stability. The antioxidant triphenyl
phosphorothioate (TPPT) was also tested in some blends. The biodiesel blends B20,
B30 and B40 enables single phased diesel fuel or HVO with varied solketal content
(2 and 10%) at a constant biodiesel amount. No effect of solketal on fuel aging
was observed. However, HVO-containing blends tend to lower the thermo-chemical
stability relative to diesel fuel.
