Professional Design Pseudo Boehmite Powder - Silica-Alumina Gel – Ton Year Detail:
Product Performance:
A white gel (wet) or powder (dried), odorless, tasteless and nontoxic. It is a thixotrope with the characters of high purity crystalline phase, EXCELLENT GELATION and strong caking property.
It is a cement of the cracking catalyst for semi-synthetic rare-earth Y molecular sieve, a cement in aluminum silicate refractory fiber, a catalyst in making ethylene by alcohol dehydration and in making epoxy ethane. It also can be used as raw material for activated alumina and other aluminates.
Pseudoboehmite Application:
1. FCC and hydrogenation catalyst carrier.
2. Cement in aluminum silicate refractory fiber.
3. Catalyst in making ethylene by alcohol dehydration and in making epoxy ethane.
4. Used as raw material for activated alumina and other aluminates.

A white powder, easily soluble in strong acid and alkali solution. It has the advantage of good forming performance, strong adhesion, low bulk density and low sulfide content.
A-AS-HC-GSA can be used as the raw material of petroleum refining catalyst and hydrotreating catalyst.It can improve the activity of hydrocracking catalyst either.
