摘要：对生物质快速裂解油在700～900℃温度范围内分别进行了高温裂解(空白实验1)、水蒸汽重整(空白实验2)和水蒸汽催化重整。实验结果表明:温度是影响各组实验结果的关键因素。较高温度下(>800℃)水蒸汽的存在更好地促进了生物质油裂解中间产物的水气变换反应。在有足量水蒸汽存在的情况下,镍基催化剂的存在可以在较低温度下得到较高的氢摩尔分率、目的产品气纯度、氢产率和气相产品碳元素选择性,温度高于850℃时,镍基催化剂只对气相产品中的一氧化碳和甲烷的水气变换反应有促进作用,气相产品碳元素总体选择性此时只受温度的影响。
Decomposition （blank experiment 1）, steam reforming （blank experiment 2） and catalytic steam reforming of fast pyrolysis bio-oil were carried out respectively in the temperature range of 700 - 900℃. Temperature is the key factor that influencing the experiment results. The existence of steam at relative higher temperature （ 〉 800℃） favors the watergas shift reaction of intermediate product deriving from bio-oil＇ s early decomposition. Higher mole fraction of hydrogen, desirable product gases purity, hydrogen yield and carbon selectivity of product gases were obtained in the presence of Ni- based catalyst. In the saturated steam, Ni-based catalyst favors the water-gas shift reaction of carbon monoxide and methane only, and the carbon selectivity of product gases is the function of temperature when it is higher than 850℃.
