TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Component: The oxygen-containing gas is air, pure oxygen or their composite. The oxygen content of the oxygen-containing gas is 0.8-1.5 molar valent weight of the carbon content of the coal and the cellulose biomass. The synthesis gas comprises hydrogen and carbon monoxide, where the molar ratio of the hydrogen and carbon monoxide is 1:10-10:1. The catalyst is a catalyzing system comprising molybdenum sulfide and an activation alkane product carbon (C)-hydrogen (H) bond. The activation alkane product C-H bond is molybdenum, vanadium, osmium, rhenium, iridium, palladium, cobalt, rhodium, nickel or their composite. The catalyzing system adopts a settling method, and/or is loaded on a carrier. The constituent of the catalyzing system is Mo-S-M-L, where the molar content is Mo (100%)-S (175-200%)-M (10-100%)-L (150-190%).M=a constituent of the activation alkane product C-H bond, preferably Mo, V, Os, Re, Ir, Pd, Co, Rh, Ni or their composite; andL=an alkali metal compound used as a spiked constituent in the catalyzing system, preferably Li, Na, K, Rb, or Pd salts.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Method: The gasifying process is carried out in the presence of an oxygen-containing gas.
