    Oil Column Formed Alumina Ball

    The oil column formed alumina ball is made of pseudo-boehmite as raw material, After it is peptize to form aluminum sol, it is mixed with gelling agent, and Shape by dropping it into hot oil through a dispersing dropper, After aging, washing, drying, and baking, the spheres alumina carrier is obtained. Compared with other forming methods, the spherical alumina prepared by oil column forming has the characteristics of good pore structure, concentrated pore distribution, uniform pore size, high strength, low bulk density, and regu

    Titanium Silicon Molecula

    Titanium silicon molecular sieves are formed by Ti atoms partially replacing aluminum atoms insilica-aluminum molecular sieves, belonging to the ZSM-5 series zeolite molecular sieves, withMFI topological structure. The primary structural units, such as silica-oxygen tetrahedrons andtitanic-oxygen tetrahedrons, are connected by oxygen Bridges to form the secondary structuralunits of five-membered rings, and fiurther form a three-dimensional microporous skeleton. MFlmolecular sieve has a two-dimensional pore stucture, the 10-member...

    Zeolite Molecular Sieve

    Zeolite molecular sieves have a porous framework structure, with numerous uniformly sized channels and neatly arranged cavities on the inner surface. Therefore, they possess excellent physical and chemical properties such as adsorption, separation, ion exchange, and catalysis. This characteristic makes them widely used in industries such as petrochemicals, agriculture, medicine, machinery, electronics, and water treatment.

    Activated Alumina

    The general term used for alumina in catalysts is "activated alumina," which is a porous, highly dispersed solid material with a large surface area and its microporous surface has the required properties for catalysis, such as adsorption, surface activity, and excellent thermal stability, so it is widely used as a catalyst and carrier for chemical reactions.

    Pseudoboehmite

    Para-boehmite, also known as monohydrate alumina, pseudo-monohydrate soft alumina, is non-toxic tasteless, odorless, and white colloidal. It can be used as a binder for the cracking catalyst of semi-synthetic rare earth Y-type molecular sieves, a binder for silica-alumina refractory fibers, a catalyst for alcohol dehydration to ethylene, and a catalyst for the oxidation of ethane

    Catalyst & Carrier

    The catalyst carrier is also called support, which is one of the components of the supported catalyst. The catalytically active group is loaded on the surface of the, and the carrier is mainly used to support the active group, so that the catalyst has specific physical properties, and the carrier itself generally does not have catalytic activity. Most carriers products of the catalyst industry, such as alumina carriers, silica gel carriers, activated carbon carriers and some natural products such as pumice, diatomaceous earth.
