摘要：制备了Ni/Al2O3、Ni-Cu/Al2O3、Ni-Co/Al2O3和Ni-Co-Cu/Al2O3催化剂,研究了Co和Cu对生物油水蒸气催化重整的影响。实验表明,Co能促进水汽变换(WGS)反应,提高氢气的产率,Cu能抑制反应中焦炭的形成,提高催化剂的稳定性。对催化剂Ni-Co-Cu/Al2O3进行工艺条件考察,当900℃、水油比为6 g/g、质量空速(WHSV)为1 h-1时,碳选择性达到87.5%,氢气产率达到84.2%,潜在氢气产率达到92.4%。
Ni/Al2O3 catalyst was selected as the reference catalyst for steam reforming of model bio-oil to produce hydrogen.Ni-Cu/Al2O3,Ni-Co/Al2O3 and Ni-Co-Cu/Al2O3 were prepared to investigate the influence of Co and Ni on steam reforming of bio-oil.The results show that Co can enhance the water gas shift（WGS）reaction rate,and Cu can prevent the formation of coke.The reaction conditions for the steam reforming of biooil with the Ni-Co-Cu/Al2O3 catalyst were optimized as the follows：temperature of 900 ℃,water-oil ratio（the mass ratio of steam to oil） of 6 g/g and weight hourly space velocity（WHSV） of 1 h.The carbon selectivity of 87.5%,hydrogen yield of 84.2%and potential hydrogen yield of 92.4%can be obtained at the optimum conditions.
