Abstract
The present invention provides an apparatus and a method for continuous hydrogenation of conjugated diene polymer. By feeding the conjugated diene polymer, a catalyst composition and a hydrogen to the apparatus for hydrogenation. This apparatus for hydrogenation includes at least one hydrogenation reaction unit each comprising at least one a hydrogenation reactor with an outlet and at least one heat exchanger. In the hydrogenation reaction unit, the conjugated diene polymer, the catalyst composition and the hydrogen are mixed in a non-mechanical mixing mode and proceed hydrogenation with heat exchanger being connected to the outlet of the hydrogenation reactor.

A method for hydrogenating conjugated diene polymer, comprising steps of
- (a) providing an apparatus for hydrogenation, which comprises at least one hydrogenation reaction unit each comprising at least one hydrogenation reactor with an outlet, and a heat exchanger connected to the outlet of the hydrogenation reactor;
- (b) feeding a conjugated diene polymer, a catalyst and a hydrogen gas into the hydrogenation reactor, and mixing them in a non-blending manner for hydrogenation to obtain a hydrogenated mixture;
- and
- (c) introducing the hydrogenated mixture into the heat exchanger through the outlet to move away heat and obtain a hydrogenated conjugated diene polymer.
