英文摘要	a cu-zn-al methanol catalyst combined with hzsm-5 was used for dimethyl ether (dme) synthesis from a biomass-derived syngas containing nitrogen. the syngas was produced by air-steam gasification of pine sawdust in a bubbling fluidized bed biomass, gasifier with a dry reforming reaction over ultra-stable nio-mgo catalyst packed in a downstream reactor for stoichiometric factor (h(2), co, co(2)) adjustment. it constantly gave syngas with h(2)/co ratio of 1.5 and containing trace ch(4) and co(2) during a period of 150 h. the obtained n(2)-containing biomass-derived syngas was used directly for dme synthesis. about 75% co per-pass conversion and 66.7% dme selectivity could be achieved under the condition of 533 k, 4 mpa and 1,000-4,000 h(-1). the maximized dme yield, 244 g dmie/kg(biomass) (dry basis), was achieved under a gasification temperature of 1,073 k, er (equivalence ratio) of 0.24, s/b (steam to biomass ratio) of 0.72 and reforming temperature of 1,023 k with the addition of 0.54 nm(3) biogas/kg(biomass) (dry basis).
