Selective Synthesis of Ethylene from Synthesis Gas over Hybrid Catalyst System

Selective synthesis of ethylene from synthesis gas has been investigated by using a hybrid catalyst system which was composed of an ethanol synthesis catalyst and zeolite as a dehydration catalyst. Ethylene was produced with a 45% selectivity from synthesis gas by the combination of Rh–Ti–Fe–Ir/SiO2 catalyst and H-Silicalite catalyst.
