  • Catalytic-reactor for carrying out conjugate chemical reactions
    Patent number: 4014657
    Abstract: A catalytic reactor for carrying out conjugate chemical reactions, comprising a body with a system of plates arranged in said body parallel to one another and having their edges built into said body, said plates being made of a material selectively permeable to a reactant common to the reactions to be conjugated and possessing catalytic activity with regard to the both reactions being conjugated.The said plates subdivide the inner space of the reactor body into a plurality of chambers intercommunicating in an alternate pattern through the intermediary of channels provided in the walls of the reactor body, so that two compartments are formed, each of these compartments serving for carrying out one of the two reactions being conjugated.
    Type: Grant

    Date of Patent: March 29, 1977
    Inventors: Vladimir Mikhailovich Gryaznov, Viktor Sergeevich Smirnov, Alexandr Petrovich Mischenko, Sergei Ivanovich Aladyshev
  • Method for carrying out simultaneously the catalytic reactions involving hydrogen evolution and consumption
    Patent number: 3950447
    Abstract: A method for carrying out simultaneously the catalytic reactions involving the evolution and consumption of hydrogen, which comprises conducting the reactions in a reaction space divided by a partition made from a material that is selectively permeable to hydrogen only and serves as a catalyst.
