Special Pseudo Boehmite

Special Pseudo Boehmite
Product Details

P-DF-10 

P-DF-10 is a middle density, large pore size pseudo-boehmite product, with the character of high purity, large pore volume, uniform pore size distribution and good acid-soluble.

For the large pore volume, specific surface area, good thermal stability, P-DF-10 has good formability, high strength and good wear resistance characteristics, which is widely used in hydrocracking, hydrotreating, hydrogenation refining catalyst

H-B-90

H-B-90 Is a β-Al (OH) 3 powder produced by high liquidity special process. It’s insoluble in acid. As catalyst components, H-B-90 has the  unique properties of lower the acid active center density.

After the molding process, it can be made into many shapes such as bar, ball and Special-shaped. H-B-90  is widely used in high acid activity center catalyst field.
