Activated carbon adsorbent

Abstract

The invention discloses an activated carbon adsorbent which is prepared from the following raw materials in parts by weight: 49-60 parts of calcium chloride, 17-32 parts of activated carbon, 12-15 parts of water, 6-7 parts of bentonite, 1-5 parts of iron sesquioxide, 2-6 parts of polyurethane, 10-20 parts of an emulsifier, 2-10 parts of butyl ester and 2-6 parts of hexamethylenetetramine. The activated carbon adsorbent disclosed by the invention has the advantages that since the activated carbon is taken as a matrix in the mixed adsorbent, the gas permeability and volume filling quantity of the adsorbent are greatly improved; and meanwhile, because the filling density is increased, the heat transfer property of the adsorbent is greatly improved, the air conditioning condition refrigerating capacity can be improved by about 35% under the condition of adsorbent beds of the same volume, and the refrigerating capacity can be improved by about 28% under ice-making conditions.

Description

technical field [0001] The invention relates to an adsorbent, in particular to an activated carbon adsorbent. Background technique [0002] As a green refrigeration technology driven by renewable energy or low-grade waste heat, adsorption heating / heat pump technology has attracted more and more attention. The adsorbents currently used in adsorption refrigeration / heat pump systems mainly include physical adsorbents, chemical adsorbents, and physical-chemical mixed adsorbents. Compared with physical adsorbents, chemical adsorbents have the advantages of large adsorption and desorption capacity, high cooling and heating power, etc., but also have disadvantages such as poor heat transfer, poor gas permeability, and serious expansion. In order to solve the problem of chemical adsorbents Due to these shortcomings, the research on mixed adsorbents has become a hot spot at present. Contents of the invention [0003] The technical problem to be solved by the present invention is ...
