Methods for preparing fuel additives

A method for preparing a substituted fuel additive d is provided. The method comprises carrying out the following reaction: (a) (b) (d), The fuel additive d may be used as an octane-boosting additive in a fuel for a spark-ignition internal combustion engine. 

Hydrogenation of methyl acetate to methanol and ethanol by feeding a hydrogenation feed of methyl acetate, water, hydrogen and a carbon oxide into a hydrogenation unit containing a copper-zinc oxide hydrogenation catalyst to produce a hydrogenation product stream of ethanol, methanol, unreacted methyl acetate, water, unreacted hydrogen, carbon monoxide, carbon dioxide, and ethyl acetate. The hydrogenation unit is operated in the vapor phase at elevated temperature and pressure. The total molar ratio of hydrogen to methyl acetate fed to the hydrogenation unit is 5:1 to 20:1. The total molar ratio of methyl acetate to carbon oxide(s) fed to the hydrogenation unit is 1:2 to 100:1. The hydrogenation product stream is separated into a liquid stream containing ethanol, methanol, unreacted methyl acetate, water and ethyl acetate, and a gaseous stream containing unreacted hydrogen, carbon monoxide and carbon dioxide, and a portion of the gaseous stream is recycled to the hydrogenation unit.

Process for producing ethanol

The present invention relates to an improved process for the production of ethanol from a carbonaceous feedstock; wherein the carbonaceous feedstock is first converted to synthesis gas which is then converted to ethanoic acid, which is then esterified and which is then hydrogenated to produce ethanol.

Process for the production of alcohol from a carbonaceous feedstock

Process for the preparation of alcohol(s) from alkyl ester(s) by bringing hydrogen, carbon monoxide and at least one alkyl ester into contact with a hydrogenation catalyst including copper and manganese in a reaction zone to produce at least one alcohol. The molar ratio of hydrogen to carbon monoxide in the reaction zone is in the range of from 100:1 to 1:10.

Process for hydrogenating alkyl ester(s) in the presence of carbon monoxide

Process for the production of methyl acetate by carbonylating a dimethyl ether feed with carbon monoxide under substantially anhydrous conditions, in the presence of a zeolite catalyst effective for the carbonylation. The carbonylation is carried out at a temperature in the range of 275 to 350&#xb0; C. and in the presence of hydrogen.
