The non-aromatic solvents such as cyclohexane, tetrahydrofuran (THF) and n-hexane, and the addi-tive with strong basicity e.g. KOH, were necessary for smooth conversion of the substrate. That the catalyst can be recov-ered and reused for nine times without loss of catalytic activity indicates that this catalyst is a recyclable one for benzal-dehyde reduction.展开更多

Pure water, NaOH solution and MDEA were adopted as the absorbents. The performance of the two kinds of membranes for separation of SO2 was evaluated in terms of the concentration of absorbent solution, the concentration of SO2, and the feed flow rate. The efficiency for removal of SO2 increased with an increasing absorbent concentration. Upon increasing the concentration of SO2 and the feed flow rate, the desulfurization efficiency was decreased.展开更多
