摘　　要：Available interphase area is an important part of investigating catalytic distillation process by the use of a nonequilibrium stage rate model.In this paper the available interphase area,when gas and liquid flow countercurrently in catalyst bed within a distillation column,was measured by using the chemical method in which CO2 in the air is analyzed by Na2CO3-NaHCO3 buffer solution with AsO2 as catalyst.The surface renewal theory by Danckwerts was employed for data processing.Available interphase area is an important part of investigating catalytic distillation process by the use of a nonequilibrium stage rate model.In this paper the available interphase area,when gas and liquid flow countercurrently in catalyst bed within a distillation column,was measured by using the chemical method in which CO2 in the air is analyzed by Na2CO3-NaHCO3 buffer solution with AsO2 as catalyst.The surface renewal theory by Danckwerts was employed for data processing.
