甲烷二氧化碳氧气氧化重整抗积碳催化剂的研究

STUDY ON CARBON-DEPOSITION RESISTANT CATALYSTS FOR OXIDATIVE REFORMING OF CH_4 WITH CO_2 AND O_2

采用溶胶-凝胶方法合成了 La_2Zr_2O_x 烧绿石。这种烧绿石结构稳定,并具有合适的中孔以及合理的比表面积,是一种具有潜在应用前景的催化剂载体。以 La_2Zr_2O_x 烧绿石为载体制缶的负载镍催化剂,在甲烷二氧化碳氧气氧化重整反应中显示了极好的稳定性.

La_2Zr_2O_x with pyrochlorc structure was synthesized by the sol-gel process.This kind of materials, having stable structure,suitable mcsoporcs and reasonably high specific surface area,might be u poten- tial catalyst carrier.It is found that a La_2Zr_2O_x supported Ni catalyst exhibits excellent stability in oxidative reforming of CH_4 with CO_2 and O_2.
