Benefits of technology

This patented technology describes an improved type called Silane/Aluminium Hydroxy Layer (SiO2H) dried glue used during hydrocracking processes. These new materials have better stability at high temperatures compared to traditional methods like liquid paraffin or ethanol solvent systems due to their ability to mix different types of chemical elements together without losing them altogether. Additionally, these compositions also allow for effective use within certain conditions such as light oil refining operations where there may occur thermal decomposition reactions between oxygen atoms and alkoxides. Overall, this technical effect provides superior results when applied to various industrial applications including upgraded petroleums from crude distillers.

Problems solved by technology

This patented technical describes how certain materials like titanium dioxide (TiO2) react quickly without losing their ability to absorb oxygen molecules during use. To solve these issues, researchers developed new techniques called redoxy technology, specifically involving adding bismuth trioxide (BTO) to create ceramics made from Titanium dihydroxide particles. These processes involve forming stable structures through complex interactions among metal atoms within the crystal lattice framework. By combining them together, they enhance the desired physical/chemical property of the material while maintain its original functionality.

Abstract

The invention discloses aluminum hydroxide dry glue containing silicon and boron and a preparation method thereof. A silicon source in the method adopts an organic silicon source which is added after the aluminum oxide is gelatinized, and a boron source adopts boron-containing organic compound solution which is added after the silicon source is added and aged, so silicon and boron auxiliary agents are uniformly distributed on the aluminum oxide, in addition, the hole structure and the acid property of the aluminum oxide are regulated, and the aluminum hydroxide dry glue has the characteristics of large pore volume, large specific surface area and concentrated hole distribution and is particularly applicable to catalysis materials of hydrotreating catalysts.
