中文摘要direct conversion of biomass-derived syngas (bio-syngas) to dimethyl ether (dme) at pilot-scale (100 t/a) was carried out via pyrolysis/gasification of corncob. the yield rate of raw bio-syngas was 40-45 nm(3)/h with less than 20 mg/nm(3) of tar content when the feedrate of dried corncob was 45-50 kg/h. after absorption of o(2), s, cl by a series of absorbers and partial removal of co(2) by the pressure-swing adsorption (psa) unit sequentially, the obtained bio-syngas (h(2)/co approximate to 1) was directly synthesized to dme over cu/zn/al/hzsm-5 catalyst in the fixed-bed tubular reactor. co conversion and dme space-time yield (sty) were 67.7% and 281.2 kg/m(cat)(3)/h respectively at 260 degrees c, 4.3 mpa and 3000 h(-1) (ghsv, syngas hourly space velocity). synthesis performance would be increased if the tail gas (h(2)/co > 2) was recycled to the reactor when ghsv was 650-3000 h(-1).
