The mass transter can be enhanced ,when we introduce sulfuric acid and cuprous oxide into this system.The model is formed to describe the transference of the martial between the four phases: gas-liquid-liquid-gas, which can explain some problems. We analyze the dead of the catalyst, and make a conclusion that the surface of the catalyst is covered with some compounds such as bluestone, which lessen the activity points of the catalyst and debase the activity.

在SO_4~(2-)／ZrO_2-La_2O_3催化的反应系统中加入稀硫酸和氧化亚铜促进了异丁烯和一氧化碳的传质、使反应得以快速，高选择性的进行，异丁烯的转化率达95％以上，特戊酸的收率达47％；讨论了g-l-l-s传质过程；对催化剂作了失活分析，催化剂失活的原因是因为反应后的催化剂表面覆盖了一层硫酸盐，使催化剂的活性中心数减少，活性降低。
