<p><P>PROBLEM TO BE SOLVED: To provide a biomass-derived fuel gas composition that can be directly mixed with and substitute for liquefied petroleum gas which is a conventional fossil fuel. <P>SOLUTION: The liquefied fuel gas composition has a sulfur content of≤10 mass ppm and contains 1.0-99.0 mol% 3C hydrocarbon and 1.0-99.0 mol% 4C hydrocarbon. The liquefied fuel gas composition is obtained by bringing a stock oil into contact with a hydrocracking catalyst under hydrogen pressure, wherein the stock oil comprises a hydrocarbon fraction containing animal and vegetable oils and fats and/or components derived therefrom, and the hydrocracking catalyst contains at least one metal chosen from groups 6A and 8 of the periodic table and an inorganic oxide having an acidic property. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
