  • Composite for catalytic distillation and its preparation
    Patent number: 7642388
    Abstract: The present invention relates to a composite for catalytic distillation, comprising a substrate material, and a modifying material and an active material, wherein said substrate material is made of porous materials, said modified material comprises at least one metal oxide, and said active material comprises an active component for a catalytic reaction. The catalytic distillation composite according to the present invention serves as both distillation packings and catalysts, and can allow catalysts to make the best of its efficiency, provide sufficient contact areas between gas and liquid phases, which facilitates mass transfer between gas and liquid phases, boosts effects in both reaction and separation and is liable for filling, removing and utilizing in industries.
    Type: Grant
