Title:
METHOD FOR PRODUCING ETHYLENE
Document Type and Number:
WIPO Patent Application WO/2019/124519
Kind Code:
A1
Abstract:
The invention addresses the problem of providing a method for producing ethylene that uses propylene as starting material and that, during ethylene production, stably produces ethylene on a long-term basis while minimizing reductions in the ethylene yield. The method for producing ethylene is characterized by comprising: a step (I) for feeding propylene to a reactor and allowing the propylene to be in contact with a catalyst so as to produce ethylene; and a step (II) for regenerating the catalyst that has been used in the step (I).
