通过对HZSM 5,HZRP 1和Hβ三种类型分子筛催化剂上合成甲基叔丁基醚的活性测定和结构表征 ,初步考察了分子筛孔结构对催化活性的影响 .在此基础上 ,对适宜孔结构的分子筛进行了水热改性 ,考察了改性条件对分子筛催化剂的性质及其合成甲基叔丁基醚反应催化活性的影响 ,得到了催化活性较好的分子筛催化剂 . Based on the activity determination and structural characterization of methyl tert-butyl ether synthesized from three types of zeolites, such as HZSM 5, HZRP 1 and Hβ, the influence of molecular sieve pore structure on catalytic activity was investigated. Based on this, The molecular sieve was hydrothermally modified. The effects of the modification conditions on the properties of the molecular sieve catalyst and the catalytic activity of the synthesis of methyl tert-butyl ether were investigated. The zeolite catalyst with better catalytic activity was obtained.
