Abstract
This invention relates to a process for making methanol and ethanol from carbon dioxide and hydrogen. The process includes contacting a mixture of carbon dioxide and hydrogen with a catalyst system containing a ruthenium compound—and optionally, a chloride or bromide-containing compound—dispersed in a low-melting tetraorganophosphonium chloride or bromide salt under conditions effective to produce methanol and ethanol. The invention also relates to a process for making methanol and ethanol from carbon monoxide and water using the same catalyst system.
