Abstract
Process for homologation of alcohol(s), by 1 introducing alcohol(s) into an etherification unit to produce alkyl ether(s), 2, introducing at least a part of the alkyl ether(s) from step 1, together with CO and optionally H2, into a carbonylation unit, in the presence of an acidic homogeneous or heterogeneous carbonylation catalyst, to produce alkyl ester(s), and 3, introducing at least a part of the alkyl ester(s) from step 2, together with H2, into a hydrogenation unit, to produce homologated alcohol(s). Optionally, at least a part of the homologated alcohol(s) from step 3 is recycled into the etherification unit of step 1. Alcohol(s) from the hydrogenation unit of step 3 are recovered.
