Abstract
A process for making propylene oxide from propylene is disclosed. Propylene, hydrogen, and oxygen are reacted in a slurry comprising a catalyst and a solvent to produce a gaseous product stream and a liquid product stream. The gaseous product stream is contacted with an absorbent to produce a gas effluent and a liquid effluent. The gas effluent is recycled to the reaction step.
