The properties of Raschig ring: alias alumina ceramic ball, filler ball, inert porcelain, support ball, high purity filler. Uses of Lasihuan: Widely used in hydrocracking units, refining units, catalytic reforming units, isomerization units, and demethanization in petrochemical plants, chemical fiber plants, alkylbenzene plants, aromatic plants, ethylene plants, natural gas plants Filling materials such as base devices. It is used as supporting cover material and column packing for catalyst, molecular sieve, desiccant, etc. in the reactor. Its main function is to increase the gas or liquid distribution point, support and protect the active catalyst with low strength. The characteristics of Raschig ring: high purity, high strength, high temperature resistance, high pressure resistance, strong acid and alkali corrosion resistance, good thermal shock stability, and stable chemical properties.
