六铝酸盐BaNiAl_(11)O_(19-δ)对CH_4+CO_2制取合成气反应的催化性能

CATALYTIC PROPERTIES OF HEXAALUMINATE BaNiAl 11 O 19 δ FOR CO 2 REFORMING OF METHANE TO SYNTHESIS GAS

本文制备了以Ｎｉ为活性组分的六铝酸盐复合金属氧化物ＢａＮｉＡｌ１１Ｏ１９δ催化剂，考察了该催化剂催化甲烷二氧化碳重整制合成气反应的催化性能．结果表明，这种把过渡金属活性组分Ｎｉ镶嵌在晶体的晶格中形成的高温稳定的复合金属化物催化剂，催化性能稳定，活性高，７５０℃反应条件下２ｈ反应物ＣＨ４和ＣＯ２转化率分别为９２．７０％和９３．１４％，合成气Ｈ２和ＣＯ收率分别为９１．９４％和９２．９２％．

In the paper,hexaaluminate catallyst BaNiAl 11 O 19 δ containing Ni as active component was synthesized,the catalytic properties of catalyst BaNiAl 11 O 19 δ for CO 2 reforming of methane to syngas were studied.The experiment results showed that catayst BaNiAl 11 O 19 δ ,which active component transition metal Ni was inlayed in lattice,maintained stable activity,convertion of the feed gas CH 4 and CO 2 were both 92.70% and 93.14% respectively,collection of syngas H 2 and CO were both 91.2% and 92.9% respectively in situation 2 hours reaction at temperateure 750 ℃.
