A method of producing a fuel additive includes passing a feed stream comprising C4 hydrocarbons through a methyl tertiary butyl ether unit producing a first process stream; passing the first process stream through a selective hydrogenation unit producing a second process stream; passing the second process stream through an isomerization unit producing a third process stream; and passing the third process stream through a hydration unit producing the fuel additive and a recycle stream.

According to the present invention, organic material is converted to biogas through anaerobic digestion and the biogas is purified to yield a combustible fluid feedstock comprising methane. A fuel production facility utilizes or arranges to utilize combustible fluid feedstock to generate renewable hydrogen that is used to hydrogenate crude oil derived hydrocarbons in a process to make transportation or heating fuel. The renewable hydrogen is combined with crude oil derived hydrocarbons that have been desulfurized under conditions to hydrogenate the liquid hydrocarbon with the renewable hydrogen or alternatively, the renewable hydrogen can be added to a reactor operated so as to simultaneously desulfurize and hydrogenate the hydrocarbons. The present invention enables a party to receive a renewable fuel credit for the transportation or heating fuel.

Processes for co-production of methyl tertiary-butyl ether (MTBE) and alkylate is disclosed. The process includes comprising passing a hydrocarbon feed stream comprising C.sub.4 hydrocarbons to a dehydrogenation unit to generate a dehydrogenation effluent comprising C.sub.4 olefins. The dehydrogenation effluent is passed to a MTBE unit to provide a mixed stream comprising C.sub.4 olefins and MTBE. The mixed stream is separated to provide an MTBE product stream and a fractionator overhead stream comprising olefins. The fractionator overhead stream is passed to an alkylation unit to produce an alkylation product stream comprising an alkylate.
