Zeolite after treatment method

This invention relates generally to a process to perform controlled alkaline and acid treatments on inorganic porous solids, yielding superior physico-chemical and catalytic properties, whereas the particle and crystal size is not negatively influenced. Accordingly, the solids obtained in this fashion can be easily recovered from the alkaline solution. The latter being problematic in the state of the art.

20230249165 · 2023-08-10 ·

A catalytic cracking catalyst contains 10-70 wt % of a cracking active component, 10-60 wt % of a binder and 10-70 wt % of a clay. The cracking active component has 5-100 wt % of a first Y-type molecular sieve and 0-95 wt % of a second molecular sieve. The first Y-type molecular sieve is a modified molecular sieve based on the crystal modification of kaolin and has the sodium oxide content of less than 2 wt %. The process for preparing the catalyst includes the steps of vigorously mixing and stirring a cracking active component comprising a modified molecular sieve based on the crystal modification of kaolin, a binder and a clay with water; spray drying; washing; filtering; and drying. The catalyst is used in the catalytic cracking reaction of heavy oils, and has a good coke selectivity, as well as a higher heavy oil conversion rate.

METHOD FOR PRODUCING POROUS COMPOSITE BODIES WITH THERMALLY CONDUCTIVE SUPPORT STRUCTURE

In a method for producing porous composite bodies, which have a support structure made of a material having good thermal conductivity and which have at least one functional material, a multiplicity of shaped bodies (1) made of the functional material are coated with the material having good thermal conductivity and a solid connection between the coated shaped bodies (1) is established in order to form the support structure made of the material having good thermal conductivity. The coating (2) is generated with a porous structure or is provided with a porous structure, which, after the solid connection has been established, permits access for a liquid or gaseous medium through the coating to the functional material. The method permits cost-effective production of porous composite bodies with very good heat transfer properties.
