Onboard CO2 reforming of dimethyl ether can be a novel and green route for hydrogen and CO production. This paper studies CO2 reforming of DME over Ni/γ-Al2O3 catalyst for the first time. The experimental results show that CO2 reforming of DME is feasible. Conversion of DME is 100% when the temperature is higher than 550 °C, and conversion of CO2 increases sharply to 80% at 700 °C. The selectivities of H2 and CO rise with increasing reaction temperature. In addition, the reaction network and coke formation are studied through the analytical results of XRD, XPS, TG and H2-TPR testing.

CO 2二甲醚在Ni /γ-Al系的重整2 ö 3催化剂

板载二甲醚的CO 2重整可能是氢气和一氧化碳生产的一种新颖而绿色的路线。本文首次研究了Ni /γ-Al2 O 3催化剂上甲醚的CO 2重整。实验结果表明,甲醚的CO 2重整是可行的。当温度高于550°C时,DME的转化率为100%,而在700°C时,CO 2的转化率急剧增加至80%。H 2和CO的选择性随反应温度的升高而增加。此外,通过XRD,XPS,TG和H 2 -TPR测试的分析结果,研究了反应网络和焦炭的形成。
