YH-27-Macroporous Aluminum Hydroxide Powder
YH-27 is made by the aluminum sulfate method. The product is non-toxic, tasteless and odorless. The wet product is white gelatinous, and the dry product is white powder. It has large pore volume, large specific surface area and good water absorption. The radial purity is high, the moldability is good, and it has the characteristics of a thixotropic gel. The product has good dispersibility, is easily soluble in strong acid and strong alkali solutions, and has good molding properties. After being roasted and dehydrated at low temperature, it becomes highly active alumina.
Uses: Mainly used as a catalyst carrier-the raw material of activated alumina, such as as a hydrogenation catalyst raw material and as a hydrogenation catalyst carrier. It can also be used as a molecular sieve forming binder. The product is a good raw material for making various aluminum salts. After being shaped and processed, it can be used as a desiccant, adsorbent and catalyst carrier of different shapes.
