Abstract
The present invention relates to a process for making 1,4 butanediol. The process may include reacting a solution comprising 1,4-butynediol with hydrogen in a presence of a catalyst. The catalyst may include cerium.
Claims9
A catalyst for making 1,4-butanediol, the catalyst comprising:
- a skeletal metal catalyst comprising:
- at least a first element selected from the group consisting of Ni, Co, Cu, Fe, and mixtures thereof and at least a second element selected from the group consisting of aluminum, molybdenum, chromium, iron, copper, tin, zirconium, zinc, titanium, vanadium, and mixtures thereof;
- and
- cerium as a promoter, wherein the catalyst is prepared by a process comprising melting and mixing cerium oxide, a first element, and a second element to form an alloy, wherein the first element is selected from the group consisting of Ni, Co, Cu, Fe, and mixtures thereof, and the second element is selected from the group consisting of aluminum, molybdenum, chromium, iron, copper, tin, zirconium, zinc, titanium, vanadium, and mixtures thereof, wherein the cerium oxide is converted into cerium in the alloy during the melting and mixing.
