NH3 decomp catalyst has the characteristics of catalytic activity, good thermal stability, high strength and so on.

NH3 decomp catalyst is produced cooperatively by our company and Da Lian Research Institute of Chemistry and physics of China Research Academy of Science which is a new product instead of G-117 in Germany, has the characteristics of catalytic activity, good thermal stability, high strength and the function of prevent from poisonning and coking. It is mainly used in the stove of NH3 decomp and klaos of cleaning and recycling equipment coking gas, decomposing of NH3 and HCN in coke oven gas into N2, H2, CO2, effectively solve environmental pollution.

The PXZT cooperated with Beijing Dongfang Chemical Plant, has successfully developed a PZT catalyst for purification of tail-gas of acrylic acid. The catalyst has high activity, thermal and hydrothermal stability. After been put into use of assessment in a plant, the catalyst shows an excellent performance, and totally meets the requirement of industrial application.

The PXZT  has successfully developed a PZT-303 SCR DeNOX Catalyst for coal-fire power plant. The catalyst has high activity, high rate of DeNOX, high strength, wear resistance, anti-poisoning, SO2 oxidation resistance, thermal and hydrothermal stability. It is suitable for use in the deNOX system in coal-fired plant and other boilers.
