摘要:
A catalytic composite, comprising a combination of catalytically effective amounts of a platinum or palladium component, an iridium component, and a Group IVA metallic component with a carrier material containing alumina and a finely divided, zeolitic crystalline aluminosilicate, is disclosed. A specific example of the catalytic composite disclosed herein is a composite containing 0.01 to 2 wt. % platinum or palladium, 0.01 to 2 wt. % iridium and 0.01 to 5 wt. % germanium, tin or lead combined with a gamma-alumina carrier material having 0.1 to 20 wt. % of the hydrogen form of mordenite uniformly distributed therethrough. Principal utility of these catalytic composites is, broadly, in processes for the conversion of hydrocarbons and, more particularly, in a process for the production of LPG and a high octane reformate.
摘要:
A method of preparing a catalyst composition comprising as essential components thereof, a crystalline aluminosilicate with a mordenite crystal structure containing alumina fixed in combination therewith. The catalyst composition is aged in an alkaline media to yield a catalyst substantially improved in activity, particularly with respect to the transalkylation of alkylaromatic hydrocarbons.

A CATALYTIC COMPOSITE, COMPRISING A PLATINUM GROUP COMPONENT AND A GROUP IV-A METALLIC COMPONENT COMBINED WITH A CARRIER MATERIAL CONTAINING ALUMINA AND A FINELY DIVIDED CRYSTALLINE ALUMINOSILICATE, IS DISCLOSED. A SPECIFIC EXAMPLE OF THE CATALYTIC COMPOSITES DISCLOSED HEREIN IS A COMPOSITE CONTAINING 0.01 TO 2 WT. PERCENT PLATINUM AND 0.01 TO 5 WT. PERCENT GERMANIUM, COMBINED WITH A GAMMA-ALUMINA CARRIER MATERIAL HAVING 0.1 TO 20 WT. PERCENT OF THE HYDROGEN FORM OF MORDENITE UNIFORMLY DISTRIBUTED THERETHROUGH. PRINCIPAL UTILITY OF THESE CATALYTIC COMPOSITES IS, BROADLY, IN PROCESSES FOR THE CONVERSION OF HYDROCARBONS AND, MORE PARTICULARLY, IN A PROCESS FOR THE PRODUCTION OF LPG AND A HIGH OCTANE REFORMATE.
