甲烷化是循环利用CO_2,减少其排放的有效途径之一,也是气体纯化中去除微量CO_2杂质的关键步骤。结合CO_2甲烷化反应机理,综述总结了Zr O_2负载铁、钴、钯、钌、镍等金属对该反应的催化作用研究进展。
Methanation is one of the effective ways to recycle CO 2 to reduce its emissions. It is also a key step in the gas purification to remove traces of CO 2 impurities. Combining with the mechanism of CO_2 methanation, the progress of the catalytic reaction of ZrO_2 with iron, cobalt, palladium, ruthenium, nickel and other metals on the reaction was reviewed.
