Abstract
A process for making styrene is disclosed that includes reacting toluene with a C1 source and a co-feed in the presence of a catalyst in a reactor to form a first product stream comprising styrene, ethylbenzene, carbon monoxide, and hydrogen; separating the hydrogen and carbon monoxide from the first product stream to form a second stream; separating the hydrogen from the second stream to form a third stream comprising hydrogen and a fourth stream comprising carbon monoxide; wherein the fourth stream is recycled to the reactor and forms at least a portion of the co-feed.
