Hydrocarbon conversion, esp. gasoline reforming - with catalyst contg. cobalt, tin, platinum gp. metal and halogen, which has high activity and is resistant to deactivation

摘要

Hydrocarbons are converted on an acidic catalyst consisting of (a) a porous carrier contg. (b) 0.01-2 wt.% Pt. gp. metal (0.05-1%), (c) 0.1-5 (0.5-2)% Co, (d) 0.01-5 (0.05-2)% Sn, and (e) 0.1-3.5 (0.5-1.5)% halogen. The Pt. gp. metal, catalytically available Co, and Sn are uniformly distributed through the carrier. The average crystallite size of the Co and Sn is 100 angstroms. the Pt. gp. metal is present as metal, the Sn is present in an oxidn. state above that of the metal, and the Co is present as metal and/or in state which is reducible to the metal under the conversion conditions. The pref. use is the reforming of a gasoline fraction to give a high octane reformate. Other conversions include (hydro)cracking, hydrogenolysis, (hydro)isomerisation, (de)hydrogenation, desulphurisation, cyclisation, polymerisation, alkylation, and de- and trans-alkylation.
