Embodiment 1
[0063] Example 1 Preparation of separation gas 1# and adsorbent 1#
[0064] The recovery device used in this embodiment includes an adsorption device 1, a gas-liquid separation device 2, a gas storage device 3 and a liquid storage device 4 connected by pipelines; the adsorption device 1 is connected to the exhaust port of the oil displacement well to feed the oilfield mixed gas The adsorption device 1 is provided with an adsorbent 123, and the adsorbent 123 is used to absorb hydrogen sulfide in the mixed gas, and the oil field mixed gas after removing hydrogen sulfide is passed into the gas-liquid separation device 2; the gas-liquid separation device 2 is used to separate and remove hydrogen sulfide The final oilfield mixed gas obtains supercritical carbon dioxide; the gas storage device 3 communicates with the gas-liquid separation device 2 for storing the remaining gas after removing hydrogen sulfide and carbon dioxide; the liquid storage device 4 communicates with the gas-li...
