摘要：选取乙酸、丙酮、糠醛、苯酚的混合物作为生物质油模拟物,以Ni/MgO为催化剂,在常压、800℃下在固定床管式反应器中进行水蒸气催化重整制氢反应,考察了Ni/MgO催化剂与生物质油模拟物的质量比(R)对反应的影响。实验结果表明,反应稳定后的产气速率随R的增大而增大;气相产物中H2和CO2的摩尔分数和收率随R的增大而增大,CO和CH4的摩尔分数和收率则随R的增大而减小;碳元素选择性和目的产物纯度均随R的增大而增加,当R>6时,目的产物纯度大于99.9%,气相产物中几乎不含有CH4;当R<3时,催化剂上的绝对积碳量随R的增大而增加,当R≥3时,R对催化剂上的绝对积碳量影响不大。
A mixture of acetic acid, acetone, furfural and phenol was selected as model compounds of bio-oil. Hydrogen production by catalytic steam reforming of the mixture was studied under atmospheric pressure at 800 ℃ in a tubular fixed-bed reactor using Ni/MgO as catalyst. Effect of mass ratio of Ni/MgO catalyst to the mixture （R） on hydrogen production was investigated. Results indicated that after reaction reached steady state gas production rate increased with increase of R. With increase of R, mole fraction and yield of H2 and CO2, carbon selectivity, purity of desired gas products （H2, CO） increased, but mole fraction and yield of CO and CH4 decreased. When R was more than 6, mole fraction and yield of CH4 was extremely low, so the purity of desired gas products was above 99.9% after removal of CO2. When R was less than 3 total carbon deposition amount rose with rising of R, but after R was equal to or more than 3 total carbon deposition amount seemed independent of R.
