Do you understand the catalytic effect of macroporous pseudo boehmite in automotive exhaust?

The catalyst for the use of macroporous pseudo boehmite in automotive exhaust uses a three-way catalysis, which converts harmful gases such as CO, HC, and NOx into harmless carbon dioxide, water, and nitrogen through oxidation-reduction reactions. As these gas molecules are small molecules, it can be said that products with small pore sizes serve as a "just right" catalyst for the carrier adhesive of automotive exhaust, Our large pore pseudo thin alumina can adjust the pore volume according to customer requirements, with a pore volume of 5-10. Today, Yangzhou Zhongtianli would like to share with you the catalytic effect of macroporous pseudo boehmite in automotive exhaust?

Macroporous pseudo boehmite (Alooh NH2O, n=0.08-0.62) is an evolutionary series with uncertain composition, incomplete crystallization, from disorder to order, and from weak crystal to crystal. Its typical structure is very thin folded lamellar crystals, also known as gel boehmite, macroporous pseudo boehmite, boehmite colloid or boehmite like.

Due to the close correlation between the pore structure of this product and the preparation process, the physical properties of the products obtained by different methods vary greatly. For example, the macroporous pseudo boehmite prepared by the nitric acid method has the characteristic of narrow pore size distribution; Under suitable neutralization conditions, large pore and large specific surface area Al2O3 carriers can be prepared using alkaline precipitation method. The NaAlO2-CO2 rule can produce products with a relatively wide pore size distribution.

In the modern refining and chemical industry, solid catalysts are generally used in the refining industry, consisting of carriers and active components. The carrier is a special component of solid catalysts, which can increase the specific surface area, improve heat resistance and mechanical strength. It is a dispersant, adhesive, or carrier for active ingredients. There are various carriers used for catalysts, such as alumina, molecular sieves, silica gel, silica gel, activated carbon, and diatomaceous earth.

The above is the storage method and emergency measures for leakage of high-purity aluminum oxide shared by Yangzhou Zhongtianli. Friends who have added proposed boehmite are welcome to contact us.
