Abstract
An improved catalyst is disclosed for the conversion of hydrocarbons. The catalyst comprises an alumina support, a Friedel-Crafts metal halide, and a platinum-group metal component, wherein the support comprises primarily eta alumina and a small amount of gamma alumina and has a defined pore-size and acidity characteristics. An isomerization process also is disclosed which is particularly effective for the conversion of C4-C7 alkanes.
Claims5
A process for isomerizing isomerizable hydrocarbons which comprises contacting an isomerizable hydrocarbon feedstock with an isomerization catalyst having an average pore diameter of from about 35 to about 60 angstroms and a pore-acidity index of at least about 7.0 and comprising an alumina support consisting essentially of eta and gamma alumina in an eta:gamma ratio on a mass basis of from about 4:1 to about 99:1, from about 1 to 15 mass % of a Friedel-Crafts metal halide and from about 0.01 to 2 mass % on an elemental basis of a platinum-group metal component in a hydrocarbon-isomerization zone at isomerization conditions including the presence of added chloride promoter to obtain an isoparaffin-containing product.
