摘要：
A process useful in steam cracking is disclosed for selectively converting a feed comprising C4+ dienes and oxygenate to a product comprising increased C2+ monoolefins and para-xylene levels by contacting said feed under diolefin conversion conditions with a catalyst comprising a porous crystalline material having a Diffusion Parameter for 2,2-dimethylbutane of about 0.1-100 sec−1 when measured at a temperature of 120° C. and a 2,2-dimethylbutane pressure of 60 torr (8 kPa), a temperature of 430° C. and 0.5 WHSV.
