Method and apparatus for a system of particles in substitution operation during countercurrent contacting of a gas and a feed stream liquid with a packed bed.

摘要

This invention POSSIBLE FLOW SUBSTANTIALLY CONTINUOUS HYDROGEN UNIFORMLY DISTRIBUTED AND A HYDROCARBON FLUID ALONG A CATALYST BED THICK PACKAGING FOR COMPLETING SUBSTANTIALLY COMPLETE Beaker (11) of a reactor INTRODUCING gas and liquid through rings ANNULAR ALTERNATE ( 26 and 27) ALONG THE COMPLETE BEDDING AREA IN A RELATIONSHIP DESIGN SUPPLY ENOUGH TO RAISE OR SHAKE BEDDING PACKAGING CONTAINING THE cATALYST FOR SELECTED density, shape and size. IN THE RELATIONSHIP desired flow, the catalyst is introduced into the top of the bed by flowing a liquid stream viscously ON AN periodic or semicontinuous, said catalyst CONTINUOUSLY FLOWING DOWN through the vessel. The catalyst is BEDDING FUND similarly, by flowing laminar CATALYST IN A PARTICLE liquid stream. TAKING THE CATALYST efflux (32) is out of direct contact with the gas stream flowing through the bed. THE ROAD efflux CATALYST IS SUBSTANTIALLY CONSTANT IN YOUR AREA SECTIONAL AND SOME TIMES HIGHER THAN IN DIAMETER PARTICLE DIAMETER CATALYST.
