A process for conversion of a feedstock selected from the group consisting of biomass and refuse derived fuel (RDF) to provide reformulated gasoline components comprising a substantial amount of materials selected from the group consisting of ethers, alcohols, or mixtures thereof, comprising: drying said feedstock; subjecting said dried feedstock to fast pyrolysis using a vortex reactor or other means; catalytically cracking vapors resulting from said pyrolysis using a zeolite catalyst; condensing any aromatic byproduct fraction; catalytically alkylating any benzene present in said vapors after condensation; catalytically oligomerizing any remaining ethylene and propylene to higher olefins; isomerizing said olefins to reactive iso-olefins; and catalytically reacting said iso-olefins with an alcohol to form ethers or with water to form alcohols.
A process for conversion of a feedstock of refuse derived fuel (RDF) containing plastic wastes including polyvinyl chloride to provide reformulated gasoline components comprising materials selected from the group consisting of ethers, alcohols, or mixtures thereof, comprising:
The process of claim 21, wherein said catalyst is a crystalline Cu-ZSM5 catalyst with a Si/Al ratio of 75 and crystal size of 3-5.mu..
