DEFINITION

Classification: 585/710

With catalyst rehabilitation by reversion from different compound or HF complex:

(under subclass 709) Subject matter wherein the alkylation effluent or a component thereof is treated to cause a chemical reaction, this reaction serving to form a chemical compound, suitable for use as a catalytic agent or catalyst component in subsequent alkylation reactions, the compound containing atoms which entered the original alkylation as part of the catalyst.

311, for a similar process in which the chemical reaction serves also for hydrocarbon synthesis.

705, for a paraffin synthesis which involves removal of a catalyst component from a metal-hydrocarbon complex.

904, for a collection of patents drawn to catalyst rehabilitation, by the same method, in synthesis reactions other than alkylation to produce paraffins.
