We focus on improving socio-economic benefits, leverage on efficient and flexible operation mechanism, lead by scientific and technological progress, and take talents as the root. Based on the tenet of "Quality First, Customer First", the company is dedicated to providing customers with the most satisfactory products! The development of modern science and technology makes our products constantly innovate, and pay more attention to humanization to improve customer satisfaction.

Pseudoboehmite alumina, pseudoboehmite alumina powder, pseudoboehmite blinder is a white gel (wet) or powder (dried), odorless, tasteless, non-toxic. A thixotropy with characters of high purity crystalline phase, excellent gelation and strong caking property. Mainly used as a raw material for catalyst carrier-activated alumina. Also, a cement for molecular sieve and aluminum silicate refractory fiber, e.g., a cement for catalyst of semi-synthetic, rare earth Y molecular sieve cracking, a cement for catalyst in making ethylene by alcohol dehydration, ink receptive pigment in coating and in making epoxyethane. For customers with special requirements in gelation, pseudoboehmite with excellent gelation can be supplied.

Pseudoboehmite is one of alumina hydrates. There are pseudo-boehmite, pseudoboehmite, quasi-also known as monohydrate alumina, pseudoboehmite and other names, AlOOH·nH 2O, n= 0. 08~ 0. 62, no Poisonous, tasteless, odorless, white colloid (wet product) or powder (dry product). Pseudoboehmite has low crystallinity, higher water content than boehmite, and often exists in a colloidal state. At present, the preparation methods of pseudo-boehmite mainly include aluminum alkoxide hydrolysis method, acid method and alkali method (carbonization method). The main step in the production of pseudoboehmite by the hydrolysis of aluminum alkoxides is to react metal aluminum with higher alcohols in the presence of catalysts to form aluminum alkoxides. The product purity of the aluminum alcohol hydrolysis method is high, but a large amount of waste water will be formed in the production process, and the recovery cost of organic alcohol is high, resulting in the high price of pseudoboehmite

Pseudoboehmite alumina, pseudoboehmite alumina powder can be used as a binder for semi-synthetic rare earth Y-type molecular sieve cracking catalyst, a binder for aluminum silicate refractory fibers, a catalyst for alcohol dehydration to ethylene and a catalyst for ethylene oxide, etc., as well as activated alumina and other aluminum salts raw materials.

After years of hard work, the quality of the High Purity Pseudoboehmite for Residue Hydrogenation Catalyst has been greatly improved, and has received unanimous praise from the same industry. You can rest assured to buy from us. In addition to providing professional, safe, suitable and excellent quality products, we also put the services required by our customers as important as selling products. We will do our best to expand the domestic and international markets and set higher and bigger forward goals.
