AgBiVMo oxide catalytic membrane for selective oxidation of propane to acrolein

Alternative Reaction Engineering Concepts in Partial Oxidations on Oxidic Catalysts

“…In the formation of oxygenates by partial oxidations, the use of a catalytically active membrane has been proposed in order to increase the selective formation of the oxygenated intermediate (77). The gas mixture containing propane and oxygen was fed to the axis of a porous cylinder supporting the catalyst layer, and the products were collected on the outside of the device.…”

Nanoconfinement Ionic Liquid Membranes for Efficient Flow Catalytic CO2 Cycloaddition

“…As reported, membrane reactors are divided into three categories, and the function of membrane extraction reactor is to selectively remove reaction products from the reaction mixture, 41 such as esterification reaction, 42 whereas membrane distributors realize the reaction by controlling the addition of reactants to the reaction mixture, i.e., partial reaction oxidation reaction. 43 For membrane contactors, like an interfacial contactor or force flow-through, the reactants are supplied from two different sides or the premixed reactants are fed from the same side of the membrane in dead-end permeation mode. 41 Furthermore, the membrane does not need to be selective in some catalytic applications, but simply acts as a controlled reaction interface between reactants flowing on opposite sides of the membrane.…”

“…Generally, flow reactors are characterized by uninterrupted operation, good recyclability, and nonpolluting reaction products and are simple to purify. , In this regard, the development of an IL catalytic membrane reactor (CMR) combines reaction and separation in one unit, and following the strategy of process intensification, the whole process becomes simpler, and proper reactor design can not only improve the reaction yield or selectivity but also minimize costs associated with downstream separations. As reported, membrane reactors are divided into three categories, and the function of membrane extraction reactor is to selectively remove reaction products from the reaction mixture, such as esterification reaction, whereas membrane distributors realize the reaction by controlling the addition of reactants to the reaction mixture, i.e., partial reaction oxidation reaction .

Intensification of Dry Reforming of Methane on Membrane Catalyst: Confirmation and Development of the Hypothesis

“…This approach is not practically applicable to other modes of membrane reactors such as contactor and distributor [3,12,13]. It is difficult to explain the intensification of the catalytic reaction in a reactor with a membrane catalyst in the contactor mode by a change in chemical equilibrium alone, when the initial mixture of reagents is forcibly transported through the pore structure of the membrane catalyst [14,15], and the resulting reaction mixture leaves the reaction volume without separation.…”
