研究了固定床管式催化反应器中环氧乙烷水合反应过程。 HCO3-/CO32-形式的交联苯乙烯-二乙烯基苯阴离子交换树脂用作催化剂。检测过程中催化剂的失活和膨胀。已经开发了反应器的数学模型，其确定的参数充分描述了反应速率、产物分布以及催化剂失活和膨胀。
The ethylene oxide hydration process in a catalytic fixed-bed tube reactor was studied. A cross-linked styrene–divinylbenzene anion-exchange resin in the HCO3−/CO32−form was used as a catalyst. The deactivation and swelling of the catalyst during the process was detected. The mathematical model of the reactor with determined parameters adequately describing the rate of the reaction, product distribution and catalyst deactivation and swelling has been developed.
