介绍化工过程强化的两个新例 :磁稳定床反应器和悬浮床催化蒸馏过程。以细颗粒镍系非晶态合金为催化剂的磁稳定床反应器用于己内酰胺加氢精制的试验研究表明 ,与现有釜式工艺相比 ,加氢效率可提高 3～ 5倍 ,催化剂耗量降低 50 % ,并且可缩小反应器体积。新型悬浮床催化蒸馏用于负载型杂多酸催化的苯与丙烯、十二烯烷基化过程的研究表明 ,与常规固定床催化蒸馏相比 ,悬浮床催化蒸馏具有传质阻力小、催化效率高、烯烃转化率和烷基苯选择性高、投资及能耗低等优点。
Two new examples of chemical process intensification, magnetically stabilized bed (MSB) reactor and suspension catalytic distillation (SCD) process, are discussed. The exploratory study on the application of MSB reactor with fine particles of Ni based amorphous alloy as catalyst in the process of purification of caprolactam indicated that the hydrogenating efficiency of MSB reactor process was increased 3-5 times, the catalyst consumption was reduced by 50%, and the reactor volume could be reduced, as compared with that of the existing continuous tank slurry reactor process. By taking the alkylation of benzene with propylene or long chain α olefin in present of HPW/SiO 2 as model reactions, the exploratory study on the novel SCD process showed that SCD process had the advantages of lower mass transfer resistance, higher catalyst efficiency, higher conversion of olefins and better selectivity to mono alkylbenzenes, lower capital investment and energy consumption, than that of the conventional fixed bed catalytic distillation.
