Chemistry Lab Report - Gandhi Memorial International School

Chemistry Lab Report Aim: The combustion of organic compounds produces large quantities of energy. These compounds range from that of alkanes, to alkenes to even alcohols. Ethanol is a commonly used fuel in motor-cars and its usage is increasing because it is a form of renewable energy. However, what makes a good fuel?

Alcohol fuel - Wikipedia

Alcohols have been used as a fuel. The first four aliphatic alcohols (methanol, ethanol, propanol, and butanol) are of interest as fuels because they can be synthesized chemically or biologically, and they have characteristics which allow them to be used in internal combustion engines. The general chemical formula for alcohol fuel is C n H 2n+1 OH.

available. Alcohols in the range from C6 to C22 are produced. The primarily linear- and methyl-branched SAFOL 23 alcohol is produced by the hydroformu- lation of Fischer-Tropsch olefins derived from coal. The alcohol consists of approximately 55% C12 and 45% C13 carbon chain isomers. The alcohol derivatizes like highly linear alcohol

Higher mixed alcohol fuel (a synthetic blend of linear, normal alcohols) contains about 60% more BTUs per unit volume than methanol, and nearly 20% more BTUs than ethanol. Use higher mixed alcohol fuel in today's gasoline and diesel engines as a blendstock or petroleum substitute in flex-fuel vehicles.

Coal solubilization - National Energy Council

Jun 09, 1992 · Coal solubilisation involves extracting organic material from the coal into a solvent and filtering the organic-rich solvent to remove the undissolved organic and mineral matter. Various coal solubilisation methods are known. One such method involves contacting the coal with hot, e.g. about 200° C., N-methyl pyrrolidone (NMP).

Alcohol - Commercially important alcohols | Britannica

Alcohol - Alcohol - Commercially important alcohols: Methanol (methyl alcohol) was originally produced by heating wood chips in the absence of air. Some of the carbohydrates in the wood are broken down to form methanol, and the methanol vapour is then condensed. This process led to the name wood alcohol as another common name for methanol.

Three phenomena which concern coal solubilization and depolymerization were studied during this reporting period. Previous investigations have shown that lignin peroxidases mediate the oxidation of soluble coal macromolecule. Because it appears to be a substrate, soluble coal macromolecule is also an inhibitor of veratryl alcohol
