Abstract
Catalyst compositions of alumina supports containing palladium and nickel are selective in a vapor phase hydrogenolysis reaction to convert cyclic acetal compounds and/or cyclic ketal compounds in the presence of hydrogen to their corresponding hydroxy ether hydrocarbon reaction products.
Claims27
A hydrogenolysis process comprising contacting hydrogen with a cyclic compound composition comprising cyclic acetal compounds, cyclic ketal compounds, or a combination thereof in the vapor phase and in the presence of a catalyst composition to produce a hydroxy ether hydrocarbon composition, wherein the catalyst composition comprises an aluminum oxide support containing or on which is deposited:
- i. palladium present in an amount of at least 0.8 wt % and up to 5 wt % based on the weight of the catalyst composition, and
- ii. nickel present in an amount of 100 ppmw up to 5000 ppmw based on the weight of the catalyst composition.
