NiMo Raschig Ring, Grading Rings
it is hollow cylinder active bed grading material for removal of contaminants, against pressure drop build-up and distribution optimization purpose, the grading cylinders are NiMo impregnated used at the top of the hydrotprocesing reactors and similar applications.

NiMo Raschig Ring provides high void capacity to trap particulates and protect against pressure drop build-up.

NiMo Raschig Ring also provides moderate hydrogenation activity to control the saturation of reactive component and mitigate the ploymerization and fouling.
