SYSTEM FOR THE OPTIMAL GAS DISTRIBUTION IN REACTORS AND WALLS THEREOF

摘要

To achieve the optimal distribution of gas throughout the catalytic beds of reactors for heterogeneous synthesis, eliminate flow gradients and provide mechanical support with minimal dimensions of the catalyst in said beds, a multi- layer wall is formed consisting of a thin part such as to obtain the necessary pressure drop of the gas and to act almost exclusively as gas distributor, without appreciably contributing to the support of the catalyst; a part substantially without pressure drop but only as a container for the catalyst; and a very thick intermediate part so as to act substantially as the only mechanical support and to form an airspace intended to avoid the direct impact on the catalyst of the hight-speed gas and to eliminate flow gradients of said gas throughout the bed. 12
