Inorganic waste gas mainly includes sulfur oxides, nitrogen oxides,
carbon oxides, halogens and their compounds, such as sulfur
dioxide, nitrogen oxides, etc. These inorganic waste gases can also
pose a threat to the environment and human health, such as causing
acid rain, ozone layer depletion, and crop damage. Meanwhile, some
inorganic waste gases can also cause corrosion and damage to
equipment and buildings.The effective method is catalytic
combustion, which is the process of completely oxidizing harmful
combustible substances in exhaust gas into carbon dioxide and water
under the action of a catalyst.
【Application】
(1) Catalysis of automobile and motorcycle exhaust gas;
(2) Industrial organic waste gas purification and indoor air
purification;
(3) Natural gas combustion catalysis.
(4) Fluid catalytic cracking in oil refining industry.

【Product features】
(1) high temperature resistance and high aging ability: using
cerium oxide and zirconia solid solution as the matrix, some
additives (lanthanum oxide, yttrium oxide, praseodymium oxide,
neodymium oxide) are added to replace the elements, which improves
the high-temperature anti-aging ability of the products.
(2) Excellent oxygen storage and release capacity: the product has
higher oxygen storage and release rate, faster oxygen storage and
release rate and lower light off temperature
(3) Moderate particle size distribution: the medium diameter of the
material is controlled to be 2.5-3.5 μ m by using air grinding and
precise grading technology, and the particle size distribution is
narrow, which improves the coating quality and reduces the peeling
off rate.
(4) Good product stability: advanced production technology and
production equipment, standardized management, to ensure the
stability of the product.
【Packing】 25kgs/poly-drum ,500kgs/pallet
