    摘要: A novel alkylation catalyst is described which is used in processes for alkylating olefin hydrocarbons with isoparaffin hydrocarbons to produce high octane alkylate products suitable for use as a blending component of gasoline motor fuel. The novel catalyst comprises a mixture of a hydrogen halide and a sulfone. The novel alkylation catalyst is utilized in a novel process for alkylating olefin hydrocarbons with isoparaffin hydrocarbons.

    摘要: The invention concerns a process in which monoolefins are used to alkylate isoparaffins in the presence of an HF catalyst.
    An olefinic feed (14) containing dienes is selectively hydrogenated in zone (2) to reduce its diene content, and used for the HF alkylation of isoparaffin feed (26) in alkylation reactor (8). The reactor effluent (40) is passed to isostripper (32) for separation of product alkylate (54).
    The proportion of C₃ hydrocarbons in the alkylation reactor feed (30) is minimized by passing the selective hydrogenation product (24), the isoparaffin feed (26) and a recycle stream (28) into an alkylation feed stripper (23), providing an overhead C₃ stream (78, 86) and a bottoms (30) used as alkylation reactor feed. The recycle stream (28) is obtained from the overhead (58) of isostripper (32) after passing through HF stripper (12).

    摘要: O A continuous method and apparatus for contact of olefin (1,47) with paraffin (7) in the presence of HF catalyst to produce alkylate in which about one half of the olefin feedstock (1,47) is passed to each of two riser reactors (11,45) with product effluent from both reactors entering a common settling vessel (15) with return (17) of settled HF catalyst proportioned between the two reactors (11,45) and the paraffin feedstock supported as fresh or alkylate fractionator side stream recycle (5) to one reactor and as reaction product recycle from the settler (15) to the other reactor (45).
