摘    要:一种组合了合成气在线调整和甲醇合成的双段床反应器,成功应用于由生物油重整得到的富CO2合成气的高效合成甲醇.在前段催化床反应器内,富含CO2的原始生物质合成气在CuZnAlZr催化剂的催化作用下可以有效地转化为含CO的合成气.经过450 oC的合成气在线调整之后,CO2/CO的比率由6.3大幅降至1.2.经过调整后的生物质基合成气在后段催化床反应器内由工业CuZnAl催化剂催化合成甲醇,当反应条件为260 oC 和5.5 MPa时得到每小时每kg催化剂的最大甲醇

关 键 词:生物质甲醇,生物质合成气,CuZnAlZr催化剂,合成气在线调整

Abstract:A dual-reactor, assembled with the on-line syngas conditioning and methanol synthesis, was successfully applied for high efficient conversion of rich CO2 bio-oil derived syngas to bio-methanol. In the forepart catalyst bed reactor, the catalytic conversion can effectively adjust the rich-CO2crude bio-syngas into the CO-containing bio-syngas using the CuZnAlZr catalyst. After the on-line syngas conditioning at 450 oC, the CO2/CO ratio in the bio-syngas significantly decreased from 6.3 to 1.2. In the rearward catalyst bed reactor, the conversion of the conditioned bio-syngas to bio-methanol shows the maximum yield about 1.21 kg/(kgcatal·h) MeOH with a methanol selectivity of 97.9% at 260 oC and 5.05 MPa using conventional CuZnAl catalyst, which is close to the level typically obtained in the conventional methanol synthesis process using natural gas. The influences of temperature, pressure and space velocity on the bio-methanol synthesis were also investigated in detail.
Keywords:Bio-methanol  Bio-syngas  CuZnAlZr catalyst  On-line syngas conditioning
