    • A process is disclosed for performing an exothermic reaction such as the etherification of isobutylene with methanol. The feed is charged to a vertical reaction zone containing a bed of solid catalyst. Heat released by the exothermic reaction partially vaporizes the reactants, with the vapors traveling upward to a condensing zone. All of the con­densable vapors entering the condensing zone are condensed and returned downward to the catalyst bed. A single effluent stream made up of the product, excess reactants and any unreactive compounds present in the feed streams is removed from the bottom of the reaction zone. This total reflux reaction zone allows temperature control within a catalyst bed without the use of indirect heat exchangers located within the catalyst bed.
    • 公开了用于进行放热反应的方法,例如异丁烯与甲醇的醚化反应。 将进料装入含有固体催化剂床的垂直反应区。 通过放热反应释放的热量使反应物部分蒸发,蒸气向上移动到冷凝区。 进入冷凝区的所有可冷凝蒸汽都会冷凝并向下返回催化剂床。 从反应区的底部除去由产物,过量反应物和存在于进料流中的任何非反应性化合物组成的单个流出物流。 该总回流反应区允许在催化剂床内进行温度控制,而不使用位于催化剂床内的间接热交换器。
