DIRECT AND SELECTIVE PRODUCTION OF ETHANOL FROM ACETIC ACID UTILIZING A PLATINUM/TIN CATALYST

摘要

A process for selective and direct formation of ethanol from a carbon source comprising: contacting a feed stream containing acetic acid and hydrogen in vapor form at a temperature of 200ºC to 300ºC with a hydrogenating catalyst containing a combination of platinum, tin, and a third metal on a catalyst support, wherein the third metal is selected from the group consisting of palladium, rhodium, rhenium, iridium, chromium, copper, molybdenum, tungsten, vanadium, and zinc.
