Abstract
In contact processes involving a cycle of operations effected in presence of the same contact mass which contains a component favourable to one operation and unfavourable to another operation, the said component is alternately deactivated for the operation for which it is unfavourable and restored to activity for the p operation for which it is favourable. The invention is illustrated by reference to the cracking of hydrocarbons by means of an aluminium hydrosilicate catalyst as described in Specification 416,025, which is periodically regenerated by means of an oxygen-containing gas. To promote the regeneration a compound of iron, manganese, nickel, copper, or cobalt is incorporated in the contact mass. To avoid an adverse effect on the cracking operation this compound is rendered inactive by treatment with hydrogen sulphide or an organic sulphide, and it is restored to activity by the regenerating gas or by a preliminary treatment with steam or hydrogen. Specification 478,216 also is referred to.
