Abstract

The invention relates to a 13X-type zeolite-activated carbon composite material and a preparation method thereof. The grain size of the composite material is a porous structure being 1-2microns, and the pore size is 0.8-1 nanometer. The 13X-type zeolite-activated carbon composite material prepared by the invention has micro-porous and mesoporous composite pore structure characteristics and simultaneously has hydrophilcity, lipophilicity and ion exchange property. Compared with an adsorbent prepared from single-function activated carbon or coal ash, the composite material has high adsorption performance, and large-molecule polar or non-polar contaminants can be adsorbed.

Description

technical field [0001] The invention relates to a 13X zeolite-activated carbon composite material and a preparation method thereof, in particular to a 13X zeolite-activated carbon composite material prepared by utilizing quartz-rich coal gangue and a preparation method thereof. Background technique [0002] In recent years, the problem of air and environmental pollution has become a very serious problem in our country and around the world, which not only affects the growth of animals and plants, but also endangers human health. Many researchers have developed and utilized various adsorbents to solve these problems, among which activated carbon and zeolites are widely used. Activated carbon and zeolite, as two types of important industrial adsorbents, have been widely used in the separation and purification of various gases and liquids. Subject to certain restrictions. Activated carbon not only has the composite pore structure characteristics of micropores and mesopores, bu...
