Abstract
Processes and reactor systems are provided for the conversion of oxygenated hydrocarbons to hydrocarbons, ketones and alcohols useful as liquid fuels, such as gasoline, jet fuel or diesel fuel, and industrial chemicals. The process involves the conversion of mono-oxygenated hydrocarbons to aromatics and gasoline range hydrocarbons where the oxygenated hydrocarbons are derived from biomass.
Claims15
A gasoline composition, wherein the gasoline composition is derived by a method comprising:
- providing water and a biomass-derived water soluble oxygenated hydrocarbon comprising a C1+O1+ hydrocarbon in an aqueous liquid phase and/or a vapor phase,
- catalytically reacting in the liquid and/or vapor phase the oxygenated hydrocarbon with hydrogen in the presence of a deoxygenation catalyst comprising a support and a member selected from the group consisting of Re, Cu, Fe, Ru, Pt, Pd, Ni, W, Mo, Ag, Sn, an alloy thereof, and a combination thereof, at a deoxygenation temperature in the range of about 100° C. to 400° C., and a deoxygenation pressure of between 72 psig and 1300 psig, to provide a reaction stream comprising water and two or more oxygenates having two or more carbon atoms and one or two oxygen atoms, and
- catalytically reacting the oxygenates in the vapor phase in the presence of an acid catalyst comprising a member selected from the group consisting of an aluminosilicate, zirconia, tungstated aluminosilicate, tungstated zirconia, tungstated alumina, tungstated titania, a heteropolyacid, an acid modified resin, and a combination thereof, at a condensation temperature and condensation pressure to produce the C4+ compound, wherein the C4+ compound comprises a member selected from the group consisting of C4+ alcohol, C4+ ketone, C4+ alkane, C4+ alkene, C5+ cycloalkane, C5+ cycloalkene, aryl, fused aryl, and a mixture thereof, and
- distilling the product stream to provide a gasoline composition having a boiling point of less than 150° C.
