Substantially nonporous substrate supported noble metal- and lanthanide-containing catalysts for hydrogenation reactions

摘要

Aspects of the invention relate to hydrogenation catalysts, and hydrogenation processes using these catalysts, having particular characteristics, in terms of the amount and type of metal hydrogenation component (or catalytic constituent), as well as the support or substrate. The catalyst compositions, comprising both a noble metal and a lanthanide element on a substantially non-porous substrate, provide advantageous performance characteristics, including conversion, selectivity, and activity stability, as demanded in industrial hydrogenation and selective hydrogenation applications.

主权项

1. A process for hydrogenating a feedstock comprising a compound having a carbon-carbon double bond, a carbon-carbon triple bond or a carbon-heteroatom bond, the process comprising contacting the feedstock with hydrogen in the presence of a catalyst comprising a noble metal and a lanthanide element deposited on a support comprising a substantially non-porous substrate having a surface area, as measured by S.A.N2-BET or S.A.Kr-BET, from about 0.01 to about 10 m2/g.
