Special pseudo boehmite
ls-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,ls-P-DF-10 has good formability,high strength and good wear resistance characteristics,which is widely used in hydrocracking, hydrotreating,hydrogenation refining catalyst.
