It's widely used in petroleum, chemical, fertilizer, gas and environmental protection industries, as a catalyst in the reactor to cover support material and tower packing.It has a high temperature and high pressure resistance, bibulous rate is low, the characteristics of the chemical performance is stable.Can withstand the erosion of acid, alkali and other organic solvents, and can endure in the production process of temperature changes.Its main function is to increase gas or liquid distribution points, support and protection intensity is not high activity of the catalyst.
PINGXIANG A & R CERAMICS CO., LTD. has remained unwavering in its commitment to quality, uncompromising in its attention to detail and focused on being at the forefront of technology of making Honeycomb ceramic, Catalyst support ball, Random Packing, Structured packing, Activated Alumina, Molecular Sieve.
Ever keeping an eye on long run, A& R connected a gas pipeline with Pingxiang Iron& Steel company in 2000, not only did it protect the environment from pollution, it also cleared the products from impurities and blemishes. At the same time, A & R introduced a deferrization equipment to lower the iron contains less than 0.6'
