Abstract: In this paper a reactive stripping technology integrating reaction separation is presented. A multistage suspension-bed for reactive stripping reactor has been developed for simultaneously performing heterogeneous catalysis and separation. The calculation methods of the principal parameters of the above reactor are introduced. This technology and column were applied to the condensation reaction between phenol and acetone to produce bisphenol A (BPA). The acetone conversion and selectivity were all over 95%,and capacity of the catalyst reached 0. 767g BPA/(g cat ·h).
