Similarities And Differences Between Macroporous Pseudo Boehmite And Ordinary Pseudo Boehmite

  The main industrial applications of macroporous pseudo boehmite as adsorbent include gas drying, liquid drying, water purification, selective adsorption and chromatographic separation in petroleum industry. Macroporous pseudo boehmite is widely used in gas drying because of its strong affinity for water. The gases that can be dried with activated alumina mainly include acetylene, cracked gas and coke oven gas. Because activated alumina emits a lot of heat when absorbing water, comprehensive drying capacity, drying speed, heat exchange and regeneration methods should be designed.

The difference between macroporous pseudo boehmite and ordinary pseudo boehmite: macroporous pseudo boehmite products are white powder and odorless, wet products are white colloidal, dry products are white powder, with uniform pore size distribution, large volume and good water absorption. High radial purity, good molding performance, thixotropic gel characteristics. It has good dispersibility, is easily soluble in strong acid and alkali solutions, and has good molding performance. It becomes highly active aluminum oxide after low temperature roasting and dehydration. Ordinary pseudo boehmite is white powder and odorless, and pseudo boehmite is white colloidal (wet) or powdery (dry), with high crystal phase purity, good molding performance, and thixotropic gel characteristics. It is mainly used as the raw material of active alumina, the catalyst carrier, and also as the molding binder for molecular sieve and silicate refractory fiber products, such as the binder for semi synthetic rare earth Y-type molecular sieve cracking catalyst, the catalyst for alcohol dehydration to ethylene and the catalyst for ethylene oxide. The two products have different uses, and can also be produced according to customer indicators.
