中文摘要we investigated the synthesis of dimethyl ether (dme) from biomass synthesis gas using a kind of hybrid catalyst consisting of methanol and hzsm-5 zeolite in a fixed-bed reactor in a 100 ton/year pilot plant. the biomass synthesis gas was produced by oxygen-rich gasification of corn core in a two-stage fixed bed. the results showed that co conversions reached 82.00% and 73.55%, the selectivities for dme were 73.95% and 69.73%, and the space-time yields were 124.28 kg m- 3 h- 1 and 203.80 kg m- 3 h- 1 when gas hourly space velocities were 650 h- 1 and 1200 h- 1, respectively. deoxidation and tar removal from biomass synthesis gas was critical to the stable operation of the dme synthesis system. using single-pass synthesis, the h2/co ratio improved from 0.98-1.17 to 2.12-2.22. the yield of dme would be increased greatly if the exhaust was reused after removal of the co2.
