3 结论
1)采用浸渍法制备了Ni与Sn摩尔比不同的
NiSn-x/γ-Al2O3催化剂,将其用于乙二醇液相重整
(w)乙二醇水溶液、反应温度498 K、反应压力2.58 MPa、重时空速0.6 h-1、反应时间6 h的条件下,乙二醇转变为气体产物的转化率和H2选择性分别为65.4%和88.4%。Sn的加入不仅可以抑制CO加氢生H2选择性。
2)NiSn-42/γ-Al2O3催化剂具有良好的稳定
制氢反应,当Ni与Sn摩尔比为42时,制得的NiSn-42/γ-Al2O3催化剂具有最佳的活性和选择性,在5%
成烷烃,同时也可促进WGS反应,从而大幅提高
性,达到稳态时能保持初活性的34%,在生物质液相重整制氢中具有良好的应用潜力。
