Abstract:
Described herein are processes for the conversion of ethylene into CS+ olefins, naphthenics, and aromatics via a dual catalyst reaction utilizing a dearomatization catalyst.

Claim (Index 14):
An exothermic process for the conversion of ethylene in a hydrocarbon gas feed or portion thereof, said process comprising:\n a. providing at least one hydrocarbon gas feed, wherein said hydrocarbon gas feed comprises ethylene and hydrogen; b. providing at least one heterogeneous dehydroaromatization catalyst in a bed in a reactor, wherein said heterogeneous dehydroaromatization catalyst comprises\n (i) ZSM-5 in a range between 1-98.9%; \n (ii) amorphous silica, alumina, or a combination thereof in a range of 1-98.9%; \n (iii) Zn and/or Cu in a range between 0.05-3% weight; and \n (iv) at least one exchanged metal of Group IA or IIA or lanthanide series in a range of 0.05-3% weight; \n c. pretreating the heterogeneous dehydroaromatization catalyst to control its hydrogenation activity, by passing a gas stream containing hydrogen sulphide and or an organic sulfur compound over the catalyst, prior to introduction of the hydrocarbon gas feed; and d. processing, in the reactor, the hydrocarbon gas feed, to form a naphtha boiling-range product, said naphtha boiling-range product comprising at least one aromatic compound.
