Abstract

PURPOSE: A catalyst system which is composed of a combination of a Rh-Ti-Fe- Ir/SiO₂ catalyst with an alcohol dehydration catalyst is used to enable one-stage production of ethylene from synthesis gas in high efficiency.

CONSTITUTION: A conjugated catalyst system which is composed of a Rh-Ti-Fe- Ir/SiO₂ catalyst and an alcohol dehydration catalyst, preferably zeolite is used to conduct the reaction of a synthesis gas with a H₂/CO ratio of 4/1-1/4 at 250-350^oC, 1 atm-50 kg/cm² and a flow rate of 50-800 ml/min whereby ethylene is obtained from synthesis gas through a one-stage process. Both catalysts may mixed or the Rh-Ti-Fe-Ir/SiO₂ catalyst may be set in the upper part, while the dehydration catalyst in the lower part. Preferably, the amount of the dehydration catalyst is more than the other.
