Abstract
The present invention relates to a process for producing product comprising ethanol which comprises contacting a feedstock comprising acetic acid and hydrogen in a reaction zone at hydrogenation conditions with a catalyst composition comprising at least one active metal that may include a Group VIII metal and tin and from 0.01 to 0.5 wt. % cesium on a support comprising tungsten or oxides thereof.
Claims23
A process for producing ethanol, comprising:
- hydrogenating acetic acid in the presence of a catalyst comprising one or more active metals, and cesium on a support comprising tungsten or oxides thereof.
A process for producing product comprising ethanol which comprises contacting a feedstock comprising acetic acid and hydrogen in a reaction zone at hydrogenation conditions including a temperature from 125 to 350° C., a pressure of 10 kPa to 3000 kPa and a hydrogen to acetic acid molar ratio of greater than 2:1, with a catalyst composition comprising platinum, palladium or a combination thereof, tin and from 0.01 to 0.5 wt. % cesium on a silica support material comprising from 0.1 to 50 wt. % tungsten or oxides thereof.
A process for producing ethanol, comprising:
- hydrogenating acetic acid in the presence of a catalyst comprising a Group VIII metal, tin, and cesium on a support comprising tungsten or oxides thereof, wherein the Group VIII metal is selected from the group consisting of iron, cobalt, nickel, ruthenium, rhodium, palladium, platinum, osmium, iridium and combinations thereof.
