Segmented reactor for homogeneous regeneration of spent ionic liquid
10005057 · 2018-06-26 · ·

We provide a segmented reactor for regenerating a spent acidic ionic liquid via a hydrogenation reaction and hydrocracking, comprising: no solid hydrogenation catalyst; a gas inlet on one side for feeding a gas feed comprising a hydrogen; a liquid inlet on an opposite side for feeding a spent acidic ionic liquid; partitions along an axis of the reactor that create segments, wherein each segment functions as a bubble column reactor; and an outlet from which a regenerated acidic ionic liquid flows out of the segmented reactor.

ALKYLATION PROCESSES USING LIQUID LEWIS ACID CATALYSTS

An alkylation process is described. The alkylation process includes contacting a feed comprising a paraffin or an aromatic with an olefin feed in the presence of a liquid Lewis acid catalyst in an alkylation reaction zone under alkylation conditions to form a reaction mixture comprising alkylation products and the liquid Lewis acid catalyst. The liquid Lewis acid catalyst is the liquid reaction product of a donor molecule and a metal halide. The alkylation products are separated from the liquid Lewis acid catalyst and recovered.

Regeneration of an ionic liquid catalyst by hydrogenation using a macroporous noble metal catalyst

The present disclosure provides a macroporous noble metal catalyst and processes employing such catalysts for the regeneration of deactivated ionic liquid catalyst containing conjunct polymer.

Process for removing cations from an isophoronenitrile product mixture

Cations are removed from a substance stream that is produced during the production of isophoronenitrile with the help of a cation exchanger.

METHOD FOR RECOVERY OF IONIC LIQUID AND SYSTEM THEREOF

The instant disclosure relates to liquid salts such as but not limiting to ionic liquids; and method for recovering liquid salts including ionic liquids. Ionic liquids get deactivated due to presence of various contaminants or impurities. The present disclosure deals with recovery and regeneration of ionic liquids using compounds containing at least one coordinating agent to form adduct with metal compounds. The instant disclosure also includes an assembly for carrying out the recovery and regeneration of the ionic liquids.
