The influence of plasma pretreatment on the catalytic performance of Zn based catalyst in acetylene hydration was studied. Furthermore, the atmosphere (N₂, O₂, NH₃, air) and process conditions (pretreatment time, pretreatment power, gas flow) of plasma pretreatment were investigated systematically. The activity results showed that both the conversion and selectivity of the P-Zn/MCM-41 catalyst treated by oxygen plasma improved significantly. The characterization results suggested that the plasma treated catalyst enhances the mutual effect between the Zn species and MCM-41 carrier, promotes the dispersion of the active component and inhibits the loss of Zn species.

研究了等离子体预处理对乙炔水合中Zn基催化剂催化性能的影响。此外，系统地研究了等离子体预处理的气氛（N ₂，O ₂，NH ₃，空气）和工艺条件（预处理时间，预处理功率，气体流量）。活性结果表明，氧等离子体处理的P-Zn / MCM-41催化剂的转化率和选择性均得到明显提高。表征结果表明，等离子体处理的催化剂增强了Zn物种与MCM-41载体之间的相互作用，促进了活性成分的分散并抑制了Zn物种的损失。
