摘要 |
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. |
