Abstract

The invention provides a preparation method of an adsorbent for gas adsorbing separation. The adsorbent is used for the gas separation through pressure swing adsorption or temperature swing adsorption. The preparation method which treats activated carbon as a carrier comprises the following steps: dipping a copper salt and/or other assistants onto the active carbon carrier, placing the above obtained dipped activated carbon in a drying tower, and galvanizing the dipped activated carbon for heating the activated carbon in order to complete the drying process of the preparation of the adsorbent. The copper salt in the obtained adsorbent has a large load capacity and uniform dispersion on the surface of the activated carbon, so the adsorbent has a higher adsorption capability than traditional drying methods.

Description

technical field [0001] The invention provides a method for preparing a copper activated carbon adsorbent for gas adsorption and separation, which is used for pressure swing adsorption or temperature swing adsorption to separate gases. Background technique [0002] The pressure swing adsorption or temperature swing adsorption separation and purification process of gas is widely used because of its low energy consumption, operation at room temperature, high degree of automation, simple process, and devices that can be large or small. In 1985, Kawasaki Iron and Steel Corporation of Japan and Union Carbide Corporation of the United States built a 410Nm / h pressure swing adsorption purification CO device in Japan. The production capacity of a single set of large-scale CO PSA and hydrogen PSA separation and purification in the carbon-chemical industry and petrochemical industry has reached the scale of producing tens of thousands of cubic meters of gas per hour. [0003] At presen...
