生物油催化水蒸气重整制氢是一种经济可行的制氢方法。以Ni为活性剂，Al 2 O3为载体，MgO和La 2 O3为助剂，制备了Ni/MgO-La 2 O3-Al 2 O3催化剂。实验分别在固定床和流化床反应器中进行。以氢产率为指标，考察了温度、水碳摩尔比（S/C）和液时空速（LHSV）。流化床反应器在温度700-800 °C，S/C 15-20，空速0.5- 1.0h-1时，氢气产率最高，最高氢气产率为75.88%。流化床的积碳量低于固定床。在流化床中获得的最大H2产率比固定床高7%。在相同的反应温度下，流化床的积碳量低于固定床。
Catalytic steam reforming of bio-oil is an economically-feasible route which produces renewable hydrogen. The Ni/MgO-La 2 O 3 -Al 2 O 3 catalyst was prepared with Ni as active agent, Al 2 O 3 as support, and MgO and La 2 O 3 as promoters. The experiments were conducted in fixed bed and fluidized bed reactors, respectively. Temperature, steam-to-carbon mole ratio (S/C), and liquid hourly space velocity (LHSV) were investigated with hydrogen yield as index. For the fluidized bed reactor, maximum hydrogen yield was obtained under temperatures 700-800 °C, S/C 15-20, LHSV 0.5-1.0 h -1 , and the maximum H 2 yield was 75.88 %. The carbon deposition content obtained from the fluidized bed was lower than that from the fixed bed. The maximum H 2 yield obtained in the fluidized bed was 7 % higher than that of the fixed bed. The carbon deposition contents obtained from the fluidized bed was lower than that of the fixed bed at the same reaction temperature.
