Abstract
An alkylation process comprising contacting a first hydrocarbon feed comprising at least one olefin having from 2 to 6 carbon atoms and a second hydrocarbon feed comprising at least one isoparaffin having from 3 to 6 carbon atoms with a halide-based acidic ionic liquid catalyst under alkylation conditions to produce an alkylate containing an organic halide and contacting at least a portion of the alkylate with a hydrotreating catalyst in the presence of hydrogen under hydrotreating conditions to reduce the concentration of the organic halide in the alkylate is disclosed.

An alkylation process comprising contacting a first hydrocarbon feed comprising at least one olefin having from 2 to 6 carbon atoms and a second hydrocarbon feed comprising at least one isoparaffin having from 3 to 6 carbon atoms with a halide-based acidic ionic liquid catalyst under alkylation conditions to produce an alkylate containing an organic halide and contacting at least a portion of the alkylate with a hydrotreating catalyst in the presence of hydrogen under hydrotreating conditions to reduce the concentration of the organic halide in the alkylate.
In an alkylation process in which at least one olefin having from 2 to 6 carbon atoms and at least one isoparaffin having from 3 to 6 carbon atoms are contacted in an alkylation zone under alkylation conditions with a catalyst comprising a chloride-based acidic ionic liquid to produce an alkylate, the improvement comprising reacting at least a portion of the alkylate with a hydrotreating catalyst in the presence of hydrogen under hydrotreating conditions to reduce the concentration of organic chlorides in the alkylate.
An alkylation process, comprising:
- a. contacting a first hydrocarbon feed comprising at least one olefin having from 2 to 6 carbon atoms and a second hydrocarbon feed comprising at least one isoparaffin having from 3 to 6 carbon atoms with a halide-based acidic ionic liquid catalyst under alkylation conditions to produce an alkylate-containing an organic halide;
- b. adding the alkylate to other gasoline blending components to produce an alkylate gasoline;
- and
- c. contacting at least a portion of the alkylate gasoline with a hydrotreating catalyst in the presence of hydrogen under hydrotreating conditions to reduce the concentration of the organic halide in the alkylate gasoline.
