Key Laboratory of Coal Gasification and Engineering of Ministry of Education, Shanghai 200237, China

摘要

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%。

Abstract: 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 bio-oil 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^-1. 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.
