Catalytic steam gasification of waste rigid polyurethane foam, in the fixed-bed reactor, was performed to produce hydrogen-rich gas. The influence of nine kinds of additives on the yield of products (gaseous, solid and liquid product) and the volume fraction of hydrogen was investigated. Among the additives, calcium carbonate, as the catalyst, could effectively enhance the gas yield and the volume fraction of hydrogen. A three-factor three-level completely randomised factorial (3 × 3 × 3) design, with calcium carbonate as the catalyst, was applied to investigate the influence of experimental conditions (temperature, steam flowrate and catalyst dosage) on the volume fraction of gaseous product components. The data were processed with SPSS statistical software. The result showed that the main effects of one variable, the interactive effects between two factors and the interactive effects among three factors all have statistical high significance. The best catalysed process is realised when calcium carbonate is the catalyst, gasification temperature is 1100°C, steam flowrate is 0.7 kg h-1, catalyst dosage is 10 wt% of waste rigid polyurethane foam. Under this condition, the volume fraction of hydrogen reaches up to 79.85%.

通过催化蒸汽气化由废硬质聚氨酯泡沫生产富氢气体。

在固定床反应器中，对废硬质聚氨酯泡沫进行催化蒸汽气化以生产富氢气体。研究了九种添加剂对产物（气态，固态和液态产物）的收率和氢气体积分数的影响。在添加剂中，碳酸钙作为催化剂可以有效提高气体产率和氢气的体积分数。以碳酸钙为催化剂的三因素三级完全随机因式设计（3×3×3），用于研究实验条件（温度，蒸汽流量和催化剂用量）对气态体积分数的影响产品组件。数据用SPSS统计软件处理。结果表明，一个变量的主要影响是 两个因素之间的相互作用和三个因素之间的相互作用都具有统计学意义。当碳酸钙为催化剂，气化温度为1100°C，蒸汽流量为0.7 kg h-1，催化剂用量为废硬质聚氨酯泡沫的10 wt％时，可实现最佳催化工艺。在这种条件下，氢的体积分数达到了79.85％。
