activated alumina

Our annual production capacity can achieve 7000 tons activated alumina, 200 tons molecular sieve, 1200 tons catalyst and 5000 tons ammonium molybdate, but also in terms of price and there are advantages of quality products. 1. Product Introduction: The activated alumina, YH-27, which is Producing by Aluminum Sulfate Method, is nontoxic, tasteless and scentless. It is in a form of white gel when wet, and white powder when dry. YH-27 has even pore size distribution, macroporous, large specific surface area and good water absorbability. Having high radial purity and good formability, it has the characteristics of the thixotropic gel. Having good dispersibility, it is soluble in strong acid or alkali solution. It has good formability. YH-27 will turn into highly activated alumina after being roasted under low temperature and dehydration. 2.

Major Usage YH-27 is mainly used as the raw material for producing activated alumina, a kind of catalyst carrier. Specifically, it can be used as the raw material for producing hydrogenation catalysts, or hydrogenation catalyst carriers. In addition, YH-27 can be used as the binder for molecular sieve formation. It is a good material for producing various kinds of aluminum salts. After shaping and processing, it can be used to produce carriers of desiccating agents, adsorbents and catalytic agents, in various shapes. 4. Packaging and Storage The pseudo-boehmites are packaged in woven bags. Please store the products in shady, cool, ventilated and dry warehouses.
