【摘要】 催化蒸馏合成MTBE(甲基叔丁基醚)的一种新结构的催化剂包由不锈钢丝网制成,内灌以催化剂颗粒(40目),催化剂包长20cm、直径2～10cm.化学反应在蒸馏条件下进行.测定了催化剂包的有效因子和表观反应速率常数.通过数学模型计算了不同温度、不同直径的催化剂包的有效因子,结果和实测值符合较好.此结果有助于催化蒸馏塔的设计更多还原

【Abstract】 As a new type of catalyst-capsule for synthesis of methyl tert-butyl ether with catalytic distillation, the catalyst particles (40 mesh)are packed in a capsule made of stainless steel mesh. The capsule is 200mm in length and 20-100mm in diameter. The chemical reaction takes place under distillation condition. The effective factor and the apparent reaction rate constant of catalyst-capsule were determined. By means of a mathematical model, the effective factors of catalyst-capsule with various diameters and at various temperatures were calculated. The results provide useful help for design of catalytic distillation columns.更多还原
