Patent

CA 2724084

The invention provides a reaction system for the production of an alkylene carbonate comprising: - an epoxidation zone containing an epoxidation catalyst located within an epoxidation reactor; - a carboxylation zone containing an bromide-con-taining carboxylation catalyst located within an alkylene oxide absorber; and - one or more purification zones containing a purifi-cation absorbent capable of reducing the quantity of bromide-containing impurities in a feed comprising a recycle gas, which pu-rification zones are located upstream from the epoxidation zone; and a process for the production of an alkylene carbonate and an alkylene glycol.

Cette invention concerne un système de réaction destiné à la production d'un carbonate d'alkylène, qui comprend: une zone d'époxydation présentant un catalyseur d'époxydation situé à l'intérieur d'un réacteur d'époxydation; une zone de carboxylation présentant un catalyseur de carboxylation contenant du bromure situé à l'intérieur d'un absorbeur d'oxyde d'alkylène; et une ou plusieurs zones de purification présentant un absorbant de purification pouvant réduire la quantité d'impuretés contenant du bromure dans une charge d'alimentation comprenant un gaz de recyclage, lesdites zones de purification étant situées en amont à partir de la zone d'époxydation. L'invention concerne en outre un processus de production d'un carbonate d'alkylène et d'un alkylène-glycol.
