DEVICE FOR DISTRIBUTION OF GAS AND HOLDING OF CATALYST IN CATALYTIC LAYERS OF RADIAL AND AXIAL-RADIAL REACTORS

摘要

System for the production of minimum dimension walls for the optimal distribution of gas and to support the catalyst in catalytic beds in radial or axial-radial reactors consisting: a) of a single element (EP) with portions (A) permeable to gas capable of ensuring the necessary pressure drop, and portions (Bi) acting as mechanical support for the catalyst impermeable to gas; b) of an element (EC) containing the catalyst permeable to gas in direct contact with it and the portions of a) acting as mechanical support.
