Description

technical field [0001] The invention relates to a mixing molding device, in particular to a carbon molecular sieve mixing molding device. Background technique [0002] Carbon molecular sieves can be made from a wide range of raw materials, including organic molecular polymers, various coals, biomass (if shells) and petroleum by-products. The main process of preparing carbon molecular sieves is as follows: raw materials are crushed and pulverized, pre-oxidized, formed, dried, carbonized, activated, and carbon deposited to form carbon molecular sieves. [0003] The main process of the existing carbon molecular sieve mixing and forming device is as follows: After grinding and mixing the oxidized carbon molecular sieve powder and binder, it is extruded into strips by the forming device, and then broken to form the final columnar shape. The distribution of carbon molecular sieve powder in the mixture produced by the mixing device is uneven, that is, the distribution of effective...

AI Technical Summary

Problems solved by technology

This kind of columnar carbon molecular sieve is prone to overlap after stacking, which reduces the effective surface area and also reduces the adsorption efficiency.

Therefore, the existing carbon molecular sieve hybrid molding device has the problems of uneven distribution of micropores in the produced product, prone to gaps and low adsorption efficiency in practical applications.
