摘要： Propylene production processes are discussed herein. The propylene production processes may include contacting an olefin feed including butene with ethylene in the presence of a catalyst system including a metathesis catalyst under reaction conditions sufficient to form a product stream including propylene, wherein the metathesis catalyst includes molybdenum and the reaction conditions include a reaction temperature of less than 250° C.
