Abstract
Provided here are methods and systems to enhance the production of ethylene and MTBE from propylene using integrated metathesis and cracking processes. Also disclosed is a method for producing ethylene by at least partially metathesizing propylene in the presence of a metathesis catalyst in a reactor to produce ethylene and butenes, and at least partially cracking the butenes to further produce ethylene using a cracking catalyst positioned downstream of the metathesis catalyst in the same reactor, and further producing MTBE.
