With the vigorous development of national infrastructure, the chemical products market has broad application space and promising prospects. The pseudo-boehmite produced by Zibo Xiangrun and the pseudo-boehmite produced by Shandong Bairui Chemical have achieved good social and economic benefits in the domestic market, laying a solid foundation. No matter what kind of product it is, we need to experiment and research. The same is true for pseudo-boehmite. Today, let’s follow the pseudo-boehmite manufacturers Zibo Xiangrun and Shandong Bairui Chemical Co., Ltd. to find out.
Application Prospect of Pseudo Boehmite:
soda pseudo boehmite
1. It can also prepare semi-synthetic rare earth (catalyst carrier, activated alumina and other aluminum salt raw materials, such as Y-type molecular sieve cracking catalyst binder, aluminum silicate refractory fiber binder, alcohol dehydration catalyst for ethylene production, ethylene oxide alkane catalyst, etc.
γ-Al2O3 calcined at 2.400~700℃ is widely used as catalyst carrier, catalyst, adsorbent, etc. After roasting at 1100℃~1200℃, nano-scale α-Al2O3 can be obtained, which can be widely used as coating additives, advanced ceramics, high-efficiency catalysts for petrochemicals, sub-micron/nano-scale abrasive materials and abrasives, cosmetic fillers and inorganic thin film materials.
At the same time, it is also the preferred aluminum source for the synthesis of aluminum phosphate molecular sieves and heteroatom aluminum phosphate molecular sieves. For the synthesis of aluminophosphate molecular sieves and heteroatom aluminophosphate molecular sieves, the phosphorus source and the aluminum source are preferably added together with the oxygen source. On the other hand, general aluminum salts do not have oxygen atoms bonded to aluminum atoms, so when they are used as aluminum sources, it is difficult or difficult to fully secure the oxygen source, so aluminum salts are generally not used. Considering the requirement of uniform dispersion of the reaction mixture, it is hoped that the added aluminum source can be dissolved in weak acid or medium-strength acid solution, but alumina or aluminum hydroxide can only be dissolved in strong acid or strong alkali solution, which is not conducive to the dispersion of the reaction mixture. . Pseudo-boehmite is not suitable as an aluminum source, it can meet the requirements of uniform dispersion of oxygen source and reaction mixture, and is the best aluminum source in the experiment.
