Abstract
A process useful in steam cracking is disclosed for selectively converting a feed comprising C.sub.4 + dienes and oxygenate to a product comprising increased C.sub.2 + 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.sup.-1 when measured at a temperature of 120.degree. C. and a 2,2-dimethylbutane pressure of 60 torr (8 kPa), a temperature of 430.degree. C. and 0.5 WHSV.
