Problems solved by technology

However, due to the difficulty of synthesizing molecular sieve membranes on granular substrates, the prepared molecular sieve membrane layer is prone to uneven defects, which restricts the development of this type of molecular sieve membranes, especially the synthesis of micro molecular sieves such as type A on granular catalysts. There is no report on the research of membrane reactor

Abstract

This invention is a kind of catalysts separation integration of micro-membrane reactor manufacturing methods. It has the membrane granular catalyst molecular sieve that has shape-selective catalytic selective. This method use of microwave synthesis technology manufacture catalytic - Separation integration NaA molecular sieve membrane reactor. The molecular sieve membrane reactor manufacture as this method, it has dense homogeneous continuous film, and high catalysis, selective separation and have the advantages of process simple, take short time. The invention of the catalytic - from the integration of micro-membrane reactor technology manufacturing methods are: put the granular catalyst immerse to molecular sieve membrane synthesis liquor, standing and aging of 0.5 to 24 hours then implantation in the microwave at 60 ~ 130 degreeC heating Synthesis of 5 to 60 minutes, after the end of microwave heating, cooling, filtration, using deionized water wash to neutral, drying at the temperature of 70 ~ 130 degreeC, so the granular catalyst - separation Integrated membrane reactor finished.

Description

technical field [0001] The invention relates to a molecular sieve membrane reactor and a synthesis method thereof, in particular to a method for manufacturing a catalyst-separation integrated micro-membrane reactor supported by a molecular sieve membrane supported by a granular catalyst with shape-selective catalytic selectivity. Background technique [0002] A membrane reactor is an operating unit in which chemical reactions and separations occur simultaneously. Most chemical reactions are reversible and conversions are limited by thermodynamic equilibrium. By using a suitable permeable membrane to selectively remove a certain component of the reactant, the selectivity of the reversible reaction can be improved, and by selectively removing a certain component of the product through the permeable membrane, the conversion rate of the target product can be improved, thereby reducing the reaction temperature, Reactor size and downstream separation costs. [0003] As a kind of...
