Liquid fuel compositions based on catalytically deoxygenated and condensated oxygenated carbohydrates

摘要

A liquid fuel composition comprising a distillation fraction of a component having at least one C4+ compound derived from a water-soluble oxygenated hydrocarbon prepared by a method comprising: providing water and a water-soluble oxygenated hydrocarbon comprising a C1+Oi+ hydrocarbon in an aqueous liquid phase and/or a vapour phase; providing H2; catalytically reacting in the liquid and/or vapour phase the oxygenated hydrocarbon with the H2 in the presence of a deoxygenation catalyst at a deoxygenation temperature and deoxygenation pressure to produce an oxygenate comprising a CI+01-3 hydrocarbon in a reaction stream; and catalytically reacting in the liquid and/or vapour phase the oxygenate in the presence of a condensation catalyst 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, Cs+ cycloalkane, Cs+ cycloalkene, aryl, fused aryl, and a mixture thereof; wherein the liquid fuel composition is selected from: a gasoline composition having an initial boiling point in the range of from 15 'C to 70 'C (IP123), a final boiling point of at most 230 'C (IP123), a RON in the range of from 85 to 110 (ASTM 02699) and a MON in the range of from 75 to 100 (ASTM D2700); a diesel fuel composition having an initial boiling point in the range of from 130 'C to 230 'C (IP123), a final boiling point of at most 410 'C (IP123) and a cetane number in the range of from 35 to 120 (ASTM D613); and a kerosene composition having an initial boiling point in the range of from 80 to 150 'C, a final boiling point in the range of from 200 to 320 'C and a viscosity at -20 'C in the range of from 0.8 to 10 mm2/s (ASTM D445); and wherein the component having at least one C4+ compound derived from a water-soluble oxygenated hydrocarbon is less than 100 years old, as calculated from the carbon 14 concentration of the component.
