摘要: A silver catalyst comprises a sinter resistant carrier covered with finelyivided particles of a metal, a metal alloy or a partially reduced metal oxide having silver deposited thereon such that the outer surface of the particles consists essentially of monometallic silver. The metals are selected from Re, Ru, Os, Rh, Ir, Pd, Pt, Pb and Bi; the metal of the alloy from Re, Ru, Os, Rh, Ir, Pd and Pt; and the oxide from tin dioxide, lead oxide and bismuth oxide. The catalyst is useful in a variety of applications, particularly in the preparation of ethylene oxide.

摘要: The present invention provides a process for the preparation of carbon monoxide and/or hydrogen from a hydrocarbon feedstock. The hydrocarbon feedstock is subjected in a first stage to a catalytic partial oxidation process in which it is contacted, as a gaseous mixture comprising the hydrocarbon feedstock and an oxygen-containing gas, which gaseous mixture also comprises nitrogen, with a catalyst comprising as a catalytically active metal rhodium, iridium or platinum. At least a portion of the products of the first stage is subjected in a second stage to a process in which ammonia and/or hydrogen cyanide is removed.
