Solid catalyst packing structure in reactive distillation column

Reactive distillation is a new unit operation process which combines chemical reaction and distillation separation into one process.The packing structure of solid catalyst in a reactive distillation column must simultaneously meet the requirements of making both the vapor and liquid phases flow countercurrently and the reactants contact with the catalyst closely and directly as well.The basic elements for the packing structure are briefly introduced.Features,limitations and application areas of some packing structures are described in groups which have distinguishing features and good prospects for applications at home and abroad.The necessity of developing new structures is also pointed out.
