The new base form of the catalysts for hydrocarbon conversion reactor

Abstract

In this paper the stages of evolution of hydrocarbon conversion catalysts forms is traced. On the basis of author’s own data it’s shown how the properties of the catalyst bed changing at each stage. The need to transition from a cylindrical base form of hydrocarbon conversion catalysts to the spherical form is justified. It is shown experimentally and by the results of commercial use in an industrial reformer of ammonia plants, the use of spherical granules of the catalyst significantly reduces the pressure drop on furnace for routine performance, and increases the productivity of the furnace, without exceeding its reconstruction and routine drop. The results of precise measurements of the resistance of the granular layer of granules of modern catalysts for complex shapes in the real linear velocity and Reynolds number are given. Data of the macrokinetic studies confirmed the proximity of the surface of the rate constants for the methane steam reforming nickel catalyst complex shape.
