The invention discloses a supported copper-based adsorbent and a preparation method thereof. The preparation method includes the following contents: (1) mixing petroleum coke, a copper-containing compound and an activator, and activating after mixing evenly; (2) finishing the activation Then, the temperature is lowered in an inert atmosphere, and then further processing is carried out in the presence of a mixed gas of an inert atmosphere and oxygen; (3) The sample obtained in step (2) is mixed with an organic solution containing a hydroxyl group for processing, and the obtained sample is washed and dried. get the adsorbent. It overcomes the problem that the copper-based adsorbent with activated carbon as the carrier is prone to aggregation of oxides during the preparation process, and has the advantages of highly dispersed active components, excellent adsorption performance, etc., and has the advantages of simple operation, low production cost and little environmental pollution. |
