Abstract
A system for transporting particulate material uses a combination of non-mechanical valves and pneumatic and gravity transport to reduce breakage of particulate material. This system is particularly useful for the conveyance of catalyst particles where a lift conduit raises the particles from a low elevation to a relatively higher elevation. A particular advantage of the arrangement is the elimination of pneumatic conveyance through elbows to reduce pressure drop and eliminate churning of catalyst particles. The elbows are replaced with an impactless flow diverter that uses gravity assisted conveyance to eliminate or minimize the attrition resulting from pneumatic conveyance.
