摘要： An integrated process for making styrene and propene oxide which comprises the steps: a) dehydrogenating ethylbenzene in the presence of a dehydrogenation catalyst; b) separating styrene and hydrogen from the reaction mixture of step a); c) producing hydrogen peroxide from hydrogen separated in step b) and oxygen; d) reacting propene with the hydrogen peroxide obtained in step c) in the presence of an epoxidation catalyst to provide a reaction mixture comprising propene oxide; and e) separating propene oxide from the reaction mixture obtained in step d).

摘要： An integrated process for making propene oxide and an alkyl tert-butyl ether comprises dehydrogenating a feed stream comprising iso-butane to provide a stream comprising iso-butene and hydrogen and separating this stream into a stream consisting essentially of hydrogen and a stream comprising iso-butene; reacting a part or all of the stream comprising iso-butene with an alkanol in the presence of a solid acid catalyst to provide an alkyl tert-butyl ether; reacting a part or all of the stream consisting essentially of hydrogen with oxygen, providing a stream comprising hydrogen peroxide; and reacting a part or all of the stream comprising hydrogen peroxide with propene in the presence of an epoxidation catalyst to provide propene oxide.

摘要： The integrated process comprises a step a) of dehydrogenating propane providing a stream S1 comprising propane and propene; a step b) of separating stream S1 in at least one rectification column, providing an overhead product stream S2 comprising more than 99% by weight propene, a side stream S3 comprising from 90 to 98% by weight propene and a bottoms product stream S4 enriched in propane; a step c) of reacting propene with hydrogen peroxide in the presence of an epoxidation catalyst using propene in molar excess; and a step d) of separating non-reacted propene and propene oxide from the reaction mixture of step c) providing a propene oxide product and a stream S5 comprising propene and propane; wherein stream S3 is passed to step c), stream S5 is recycled to step b) and stream S4 is recycled to step a).
