FIELD: chemistry.SUBSTANCE: invention relates to a method for selective removal of gaseous reaction products from gas system including reagents and products during chemical reactions, such as synthesis of ammonia, methanol, etc., and reactors for carrying out method. Method consists in that a gaseous system is admitted to a first environment, which is separated from a second environment by a boundary wall formed by a permeation membrane, a spatially non-uniform electric field is generated between a first electrode or first group of electrodes located in first environment and a second electrode or second group of electrodes located in second environment, so that field lines of said non-uniform electric field cross said membrane, and a dielectrophoretic force generated on particles of gaseous product is a driving force of permeation through said membrane, an amount of said product being selectively removed from first environment and collected insecond environment. Particles of said product have a permanent electric dipole moment which is greater than electric dipole moment of particles of other components of gaseous system or particles said product, polarisability of which is greater than polarisability of particles of other components of gaseous system, so that electric dipole moment induced on particles of said product by non-uniform electric field is greater than electric dipole moment induced by same field on other components of system.EFFECT: invention provides efficient extraction of gaseous components of gaseous system during chemical reactions and low power consumption.14 cl, 7 dwg, 4 tbl, 1 ex |
