Gasliquid reactions are crucially important in chemical synthesis and industries. In recent years, membrane gasliquid reactors have attracted great attentions due to their high selectivity, productivity and efficiency, and easy process control and scale-up. Membrane gasliquid reactors can be divided into three categories: dispersive membrane reactor, non-dispersive membrane reactor and pore flowthrough reactor. The progress in membrane gasliquid reactors, including features, applications, advantages and limits, is briefly reviewed. (c) 2012 Society of Chemical Industry
