Products Introduction:
FCC alumina catalyst additive/carrier in here means NH-P-D pseudoboehmite( called pseudo boehmite) adopts flash dry. It is highly welcomed in the world.Its surface area and pore volume are the best in China.
Pseudoboehmite alumina are supplied as loosely agglomerated, easily dispersed, spray-dried powders (about 50 microns mean diameter) possessing high-purity, high surface area and low bulk density. Each Versal alumina particle is built from nominal 30 angstrom (3.0 nm) crystallites through a unique acid-base precipitation process using a proprietary reactor configuration that allows control of density, particle morphology, colloidal dispersibility and thermal conversion processes.
Pseudo boehmite is material of catalyst, binder, desiccant and their carrier. It used in nitrogen fertilizer, environmental protection, medicine, petrochemical industry, refractory and other industries , which is the most widely used material of catalyst and catalyst carrier.

Application of pseudoboehmite:Pseudoboehmite is used for material of catalyst, binder, desiccant and their carrier.
Storage of pseudoboehmite:
lAvoid moisture, avoid scrolling, throw and sharp shocking during transportation, rainproof facilities should be readied..
lIt should be stored in dry and ventilated warehouse to prevent contamination or moisture.
