Ethanol hydrocarbon

A useful self-terminating catalyst system (77), employs a Pd catalyst [prepared from Pd(OAc)2, NaH, and r-AmOH in THF]. The solvent required for the hydrogenation depends on the acetylene structure monosubslituted acetylenes require solvents such as hexane or octane, whereas disubstituted acetylenes need ethanol, ethanol-hydrocarbon, or ethanol-THF mixtures. In all cases it was necessary to use quinoline as a catalyst modifier. The authors consider this system one of the best for achieving both high yield and stereoselectivity. 

Fuel cells are electrochemical devices transforming the heat of combustion of a fuel (hydrogen, natural gas, methanol, ethanol, hydrocarbons, etc.) directly into electricity. The fuel is electrochemically oxidized at the anode, whereas the oxidant (oxygen from the air) is reduced at the cathode. This process does not follow Carnot s theorem, so that higher energy efficiencies are expected up to 40-50% in electrical energy and 80-85% in total energy (heat production in addition to electricity).

DOT CLASSIFICATION 5.1 Label Oxidizer SAFETY PROFILE Dangerous fire hazard by spontaneous chemical reaction. It is a very powerful oxidizer. Fires of this material should be handled like sodium peroxide fires. Moderate explosion hazard hy spontaneous chemical reaction. Explodes on contact with water, forming H2O2 and KOH. Violent reactions with air, Sb, As, O2, K. Vigorous reaction on contact with reducing materials. On contact with acid or acid fumes, it can emit toxic fumes. Incompatible with carbon, diselenium dichloride, ethanol, hydrocarbons, metals. When heated to decomposition it emits toxic fumes of K2O. See also PEROXIDES, INORGANIC. 

The addition of Cu to K/Fe oxides catalyst enhanced its ability of ethanol production. K/Cu-Fe oxides catalysts, prepared by kneading KjCO, with Cu-Fe co-precipitate, gave the ethanol selectivity of more than lOC-% at 300°C. The combination of K/Fe and Cu-Zn gave remarkable results on ethanol production. In the reaction over K/Cu-Zn-Fe oxides catalyst, CO2 conversion of 44% and ethanol selectivity of 20C-% were obtained under the standard reaction conditions. Besides ethanol, hydrocarbons were produced with a selectivity of almost 45C-%. The formation of hydrocarbons seems inevitable as long as Fe-based catalysts are employed. 

A number of these experiments at 800 torr and 75 mA using a Co—Zr catalyst showed that in the temperature range above 190 °C the catalytic reaction produced chiefly methane (Table 9) and to some extent liquid products — ethanol, hydrocarbons, formaldehyde and water — collected in a trap at 195 K.

Oil-in-water emulsions obtained with certain SPEs are stable in the presence of alcohol, which is an important advantage for many emulsion and dispersion formulations, where alcohols are common co-solvents or additives.

Combustion of this ethanol-hydrocarbon fuel forms CO2 and releases a great deal of energy (Step [3]). Photosynthesis converts atmospheric CO2 back to plant carbohydrates in Step [4], and the cycle continues.
