摘　　要：支撑β分子筛膜(载体为陶瓷拉西环)是一种新型催化精馏元件。以甲醇和混合碳四为原料,实验研究了支撑β分子筛膜在MTBE合成体系中的应用效果。结果表明:异丁烯转化率高达95%,回流比和醇烯摩尔比是异丁烯转化率的主要影响因素。与工业化树脂D005相比,支撑β分子筛膜催化精馏元件的性能较好。A novel structured catalyst packing -- beta zeolite membrane on a lu mina Raschig rings was used in catalytic distillation to synthesize methyl terti ary-butyl ether (MTBE) from C4 cuts and methanol. Almost 95 percent isobutene co nversion was achieved during performance. Reflux ratio and methanol to isobuten e ratio were the significant process variables. Comparing with industrialized ca t alyst (resin D005), supported beta zeolite membrane elements has better efficien cy.
