zr改性ni/γ-al2o3催化剂用于浆态相合成气的低温甲烷化
, PP. 966-971
Keywords: 合成气,甲烷化,天然气,浆态床,低温
Abstract:
？采用浆态床反应器,在低温(300~330℃)下进行合成气的甲烷化反应.实验中通过共浸渍法(包括含浸-旋蒸法)制备了锆(zr)修饰的ni/γ-al2o3催化剂,并考察其与单一nio、未掺杂zr的ni/γ-al2o3催化剂的催化性能差异.研究表明,载体γ-al2o3的引入能够明显地提高co的转化率和甲烷的选择性,而zr的掺杂会进一步提升催化剂的催化活性.在325℃,空速为4200ml·g-1·h-1时,co的转化率可以达到86.41%,甲烷选择性为90.53%.催化剂的表征结果表明,zr的添加促进了ni在催化剂表面的分散、减弱了活性ni与载体的相互作用,抑制了低甲烷化活性的nial2o4的生成,使得催化剂的反应性能得到较大提高.
