摘要:
In the method described, aspirated air is fed into at least one combustion chamber and the air is mixed with fuel to form a fuel/air mixture, the energy necessary to operate the engine being produced by burning the fuel/air mixture in the combustion chamber at predetermined intervals and the gases produced by the combustion being exhausted from the combustion chamber. The method is characterized in that compounds with an open or closed clathrate structure, preferably fullerenes, fullerene derivatives, fullerites, heterofullerenes, heterofullerene derivatives, fullerene fragments and/or heterofullerene fragments, are added to the aspirated air and/or fuel/air mixture and/or exhaust gas. A method of this kind gives a low fuel comsumption and reduces pollutant emission.

Use of a composition comprising a base formulation of one or more alkyl esters of a C6- C16 carboxylic acid or mixtures thereof as a fuel composition is provided. The use of the fuel composition is specifically provided for use as a lamp fuel, a lighter fuel, and/or a fuel for cooking, heating or cooling. Specifically, use of a composition as a lamp fuel is provided, wherein the composition comprises by weight 35-45% C8 methyl esters, 25- 35% C10 methyl esters, 15-25% C12 methyl esters, and/or 5-15% C14 methyl esters. Also provided is a method for producing a fuel composition comprising the steps of a) providing a vegetable oil, b) preparing alkyl esters of carboxylic acids comprised in said vegetable oil by esterification and/or transesterification, c) optionally isolating one or more of said alkyl esters of said carboxylic acids, wherein said alkyl esters of carboxylic acids comprised in said vegetable oil and/or said one or more isolated alkyl esters constitute said fuel composition.
摘要:
A method and composition for identifying chemically tagged petroleum products can be achieved by adding one or more chemicals to a selected petroleum product wherein the chemical is immune to extraction from the petroleum product by conventional inexpensive absorbents, cannot be removed by extraction with acids, bases, or immiscible solvents, cannot be easily oxidized, reduced or reacted with common agents, is difficult to disguise by masking with other agents, has a low polarity, and has a boiling point in the range of the petroleum product the chemical is being added to. The presence of the chemical is determined by using ion mobility spectroscopy.
