A combined heat exchanger and reactor for use with an ionic liquid catalyst reaction. The reactor includes an outer shell configured to receive a cooling fluid which may remove heat from reactions occurring within hollow members disposed inside of the outer shell. The hollow members preferably include one or more static mixers for mixing fluids and dispersing ionic liquid into droplets. A separation zone may be disposed beneath the hollow members which will separate the effluent and provide a hydrocarbon stream and an ionic liquid stream. Multiple combined heat exchanger and reactor may be arranged in series.

The present disclosure relates to an ionic liquid composition and a process for its preparation. The process of the present disclosure is simple, single pot and efficient process for preparing the ionic liquid composition which is effective in a Friedel Craft reaction like, alkylation reaction, trans-alkylation, and acylation.

The present disclosure envisages an ionic liquid composition comprising at least one metal hydroxide; at least one metal halide; and at least one solvent. Also envisaged is a process for preparing an ionic liquid composition. The process comprises mixing in a reaction vessel, at least one metal hydroxide and at least one metal halide in the presence of at least one solvent under a nitrogen atmosphere and continuous stirring followed by cooling under continuous stirring to obtain the ionic liquid composition.

Processes for controlling the rate and temperature of cooling fluid through a heat exchange zone in, for example, an alkylation reactor using an ionic liquid catalyst. A cooling fluid system may be used to provide the cooling fluid which includes a chiller and a reservoir. The cooling fluid may pass from the reservoir through the heat exchange zone. A bypass line may be used to pass a portion of the cooling fluid around the heat exchange zone. The amount of cooling fluid may be adjusted, with a valve, based upon the temperature of the cooled process fluid flowing out of the heat exchange zone. Some of the cooling fluid from the chiller may be circulated back to the chiller in a chiller loop.

An ionic liquid reactor and a process for controlling heat generation from an ionic liquid reactor unit. The ionic liquid reactor includes an internal heat exchanger. Impellers break the ionic liquid into small droplets to ensure reactions and mix the fluids to ensure reactions and enhance heat exchanger. Baffles may be used to direct the flow of the fluids within the reactor.

A solution containing an ionic liquid, a polymer compound including at least one of a hydrolyzable polymer compound and a thermally-decomposable polymer compound, and a laminate of layered substances is irradiated with at least one of sonic waves and radio waves. Alternatively, a solution containing an ionic liquid, a polymer compound including at least one of a hydrolyzable polymer compound and a thermally-decomposable polymer compound, and a laminate of layered substances is heated.

Systems and apparatus for ionic liquid catalyzed hydrocarbon conversion, such as alkylation, using vaporization to remove reaction heat from an ionic liquid reactor and to provide mixing therein, wherein hydrocarbon vapors are withdrawn from the ionic liquid reactor and the withdrawn hydrocarbon vapor is recovered by a hydrocarbon vapor recovery unit in fluid communication with the ionic liquid reactor for recycling condensed hydrocarbons to the ionic liquid reactor. Processes for ionic liquid catalyzed alkylation are also disclosed.
