Characteristics of carbonyl compounds (carbonyls) emissions from biodiesel–ethanol–diesel (BE–diesel) were investigated in a Commins-4B diesel engine and compared with those from fossil diesel. Acetaldehyde was the most abundant carbonyls in the exhaust, followed by formaldehyde, acetone, propionaldehyde and benzaldehyde. Apliphatic carbonyls emitted from BE–diesel were higher than those from d...

A number of studies currently focus on the renewable fuels to reduce the reliance on petroleum fuels. Biofuels such as biodiesel and bioethanol have been studied and tested in many countries including India. One of the methods to reduce the use of fossil fuel is blending ethanol with fossil diesel. However, an emulsifier or a co-solvent is needed to homogenize the diesel-ethanol blends. The ric...

Narrow temperature range distillates from biologically active solvent refined coal-l and -II heavy-end coal liquids were fraction ated according to chemical class and assayed for initiation of skin carcinogenesis in CD-1 mice. In addition, instrumental chem ical analyses were performed on the distillates and their chemical fractions. Results showed that initiation activity in these complex fuel...

Ultraviolet resonance Raman spectroscopy has been used to characterize the polycyclic aromatic hydrocarbon composition of a series of distillates of coal-derived liquids. The UV Raman spectra easily monitor changes in the polycyclic aromatic hydrocarbon composition as a function of distillation temperature. Specific species, such as pyrene, can be determined by judicious choice of excitation wa...

The taxation of diesel fuel varies by use. Consumers using diesel fuel on-road must pay state and federal highway taxes while diesel fuel consumed for residential heating, industrial use, farming or off-road travel do not pay taxes. Variation in the taxation of diesel fuel creates the incentive for firms and individuals to evade on-road diesel taxes. Firms evading on-road diesel taxes purchase ...

Abstract The casks that have contained for a certain time Sherry wines are known as Casks ® and their use value increased in recent years, they confer unique organoleptic properties to the distillates beverages aged inside them. During seasoning, these yield compounds from wood into wines, at same time, retain some which, turn, transferred casks, so acts transfer vector between two alcoholic be...

From inspection of the literature it is clear that sufficient analytical instruments for the application of oil fingerprinting on soil contamination problems are available. However well defined requirements have to be fulfilled. Among these prerequisites are the availability of unique oil signatures and sufficient variation within the different fuels on the Flemish market. On behalf of the Publ...

plants re-emit a substantial fraction of their assimilated carbon into the atmosphere as biogenic volatile organic compound. according to the presence of relatively high amount of methanol in herbal distillates, finding different concentrations of ethanol in such drinks is expectable, as several studies appeared that produced ethanol by plants emits into the atmosphere as do methanol. in this s...

The increased number of automobiles in recent years has resulted in great demand for fossil fuel. This has led to the development of automobile by using alternative fuels which include gaseous fuels, biofuels and vegetables oils as fuel. Energy from biomass and more specific bio-diesel is one of the opportunities that could cover the future demand of fossil fuel shortage. Biomass in the form of...
