Abstract :
This paper is about a problem of mathematical formulation of reactor block development taking into account ways of gas-feed flow. Influence of a configuration of reactor block on a structure of activity of the catalyst and speed of its deactivation is investigated. It is shown, that a presence of hydrodynamic irregularities diffusion gas-feed flow through catalyst bed results in different intensity of mass exchanged processes in peripheral and central zone of reactor, that reduce potential of catalyst activity and effectiveness of process. A change of feed flow direction from center to periphery is one of possible ways of partial removal of irregularities of concentration and temperature fields.
