The invention is a solid catalyst having acid strength H.sub.o less than -18. Such catalysts are characterized by the ability to react with very weak bases, such as butane, at relatively low temperatures, for example temperatures in the range from 20.degree. to 200.degree. C. The catalysts have exceptionally high activity for various hydrocarbon conversion processes, for example, because of their exceptionally high acid strength.

Solid superacid catalyst comprising group VII metal and having H.sub.o

Acyclic hydrocarbons having 4 to 7 carbon atoms per molecule are isomerized in the liquid phase by contact with a solid superacid catalyst comprising sulfated oxide or hydroxide of a metal selected from the group consisting of Group III and Group IV metals, to obtain high octane number blending components for motor fuel and/or valuable chemical and fuel intermediates.

Liquid phase isomerization of alkanes

A sulfated calcined solid catalyst which comprises (1) oxide or hydroxide of Group III or Group IV, e.g. zirconium, metal, (2) oxide or hydroxide of Group V, Group VI or Group VII, e.g. manganese or molybdenum, metal and (3) oxide or hydroxide of Group VIII, e.g. iron, or cobalt metal, is used to isomerize normal alkanes having 4 to 7 carbon atoms per molecule in the liquid phase to obtain high octane number blending components for motor fuel and/or valuable chemical and fuel intermediates.

A sulfated calcined solid catalyst is provided which comprises (1) oxide or hydroxide of Group III or Group IV, e.g. zirconium, metal, (2) oxide or hydroxide of Group V, Group VI or Group VII, e.g. manganese, metal and (3) oxide or hydroxide of Group VIII, e.g. iron, metal. In one embodiment of the invention, the catalyst is used to isomerize normal alkanes having 4 to 7 carbon atoms per molecule, to obtain high octane number blending components for motor fuel and/or valuable chemical intermediates.
