AbstractDirect 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). (C) 2009 Elsevier Ltd. All rights reserved.
