Integrated process for the production of propylene oxide

摘要

Propylene oxide may be produced by an integrated process utilizing as a basic feedstock a refinery stream containing saturated hydrocarbons. The first element of the process converts one or more of the saturated hydrocarbons to a stream containing propylene and hydrogen using steam cracking, catalytic cracking, or preferably catalytic dehydrogenation. Hydrogen and propylene are separated, and the hydrogen is employed in a reaction cycle affording hydrogen peroxide. The latter is then used to epoxidize propylene in the presence of a suitable catalyst, especially a titanosilicate.
