用程序升温脱附技术(TPD)和程序升温反应技术(TPSR),在国产0804-1型甲烷化倦化剂上进行了CO_2的TPD过程和CO,CO+H_2程序升温反应的研究。实验表明,0804-1型催化剂上存在着三种活性(吸附)中心,并对此种活性中心的脱附活化能分别进行了计算,对CO在催化剂表面的歧化反应及甲烷化反应机理进行了讨论。
The temperature-programmed desorption (TPD) and programmed temperature-programmed reaction (TPSR) were used to study the CO 2 TPD process and the CO + CO + H 2 temperature-programmed reaction on the domestic 0804-1 methanation catalyst. Experiments show that there are three kinds of active (adsorption) centers on the 0804-1 catalyst, and the activation energies of the active sites are respectively calculated. The disproportionation reactions of CO on the catalyst surface and the methanation reaction mechanism are carried out discuss.
