Abstract:
A process 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 which comprisesa) 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,b) recovering a diolefins-depleted product stream rich in monoolefins and C.sub.7 + aromatics, including para-xylene; andc) optionally recovering a C.sub.2 + monoolefins rich stream from said diolefins depleted product stream to provide a C.sub.7 + aromatics rich stream.
