The reclamation of waste rigid polyurethane foam (WRPUF) is capable of realizing both circulations of waste and protection of the environment. In our work, WRPUF was gasified and catalytic reformed in a two-stage fixed bed reactor. Steam was used as the gasification medium and NiO/CaO as the catalyst. The effect of the gasification temperature, steam flow and NiO loadings amount on the volume fraction of hydrogen in the product were investigated. The physical and chemical properties of the prepared catalyst were characterized, and the mechanism of the effect of catalyst on reforming of steam gasification gas was further studied. The results show that when the temperature was 800℃, the steam flow was 1.0 kg/h, NiO loading amount on NiO/CaO was 15wt%, the volume fraction of hydrogen was up to 84.37%.

两级固定床反应器蒸汽气化催化重整从废聚氨酯泡沫中制备富氢气体
废硬质聚氨酯泡沫塑料（WRPUF）的回收利用既可以实现废物的循环利用，又可以保护环境。在我们的工作中，WRPUF 在两级固定床反应器中进行气化和催化重整。以蒸汽为气化介质，以 NiO/CaO 为催化剂。研究了气化温度、蒸汽流量和NiO负载量对产物中氢气体积分数的影响。对制备的催化剂的理化性质进行了表征，进一步研究了催化剂对水蒸气气化气重整的作用机理。结果表明，当温度为800℃，蒸汽流量为1.0 kg/h时，NiO/CaO上的NiO负载量为15wt%，氢气的体积分数高达84.37%。
