摘要
以γ-Al2O3为载体,Pt为活性组分,采用等体积分步浸渍法制备了Pt La Ce Li/γ-Al2O3催化剂。研究了催化剂的活性和稳定性,考察了煤油液空速、水碳比、反应温度对煤油水重整制氢反应的影响。确定了最适宜的工艺条件是煤油液空速为0.06 h-1,水碳比为13,反应温度为750℃,在此条件下的氢产率为35.86 mol/mol。
PtLaCeLi/γ-Al_2O_3 catalyst was prepared by incipient wet and stepwise impregnation method with 7-A1203 as support, Pt as active component. Activity and stability of the catalyst were studied, and effects of the kerosene liquid space velocity, water/carbon ratio, and temperature on the reaction behavior of the catalyst for water reforming of kerosene to produce hydrogen were investigated. The best reaction conditions were determined as follows： liquid space velocity of kerosene 0.06 h1, water/carbon molar ratio 13,temperature 750 ~C.Under above conditions, the yield of hydrogen could reach to 35.86 mol/mol.
