PRODUCTION OF METHANOL AND ETHANOL FROM CO OR CO2

摘要

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 compoundand optionally, a chloride or bromide-containing compounddispersed 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.
