Patent ID: 8057661

Claim:
A process for the production of products which are liquid at ambient conditions and contain organic sulfur compounds of higher molecular weight than corresponding sulfur-containing compounds in the feedstock, which process comprises: providing a hydrocarbon feedstock comprising material boiling between about 60Â° C. and about 425Â° C. comprising sulfur-containing compounds at a level of sulfur up to about 5,000 parts per million and nitrogen-containing compounds at a level of nitrogen up to about 2000 parts per million, including non-basic nitrogen-containing compounds at a level up to about 200 parts per million, and a high content of olefins of up to about 60 weight percent; removing the non-basic nitrogen containing compounds from the aforesaid feedstock by an adsorption process to yield an effluent having a reduced amount of aforesaid non-basic nitrogen-containing compounds, wherein the adsorbent used in the adsorption process is selected from the group consisting of alkaline faujisite-type zeolites, alkaline earth faujisite-type zeolites, alkaline faujisite-type zeolites partially exchanged with H + or transition metals of Groups IB, IIB, IV, VIII, and mixtures thereof, alkaline earth faujisite-type zeolites partially exchanged with H + or transition metals of Groups IB, IIB, IV, VIII, and mixtures thereof, crystalline magnesium silicates, and alkaline exchanged crystalline magnesium silicates, and mixtures thereof; and contacting the aforesaid effluent with an acidic catalyst under alkylation conditions which are effective to convert a portion of the sulfur-containing compounds to higher molecular weight and higher boiling sulfur-containing compounds through alkylation by the aforesaid olefins and to produce a liquid effluent containing such higher molecular weight and higher boiling sulfur-containing compounds.
