Abstract
Mixing of gases in a catalytic reactor having plural beds of packed catalyst which are disposed in series along the direction of the reactant gas flow is improved by providing a gas-mixing means in a space prepared between each bed, said means being composed of a separator plate mounted vertically on the rear face of a grating apparatus for supporting catalyst bed for partitioning the upper part of said space, a gas-distributor tube for providing a gas to-be-mixed with the aforesaid reactant gas and a gas-dispersing board located under said tube for establishing the complete gas mixing. The typical application of this invention will be found in the reactor for catalytic dehydrogenation of ethylbenzene to produce styrene.
