Example Embodiment
[0034]Example 1: Such asfigure 2 As shown, the method of using nitrogen dioxide to enhance shale carbon dioxide adsorption performance and synergistically storing nitrogen dioxide in this embodiment specifically includes the following steps:
[0035](1) Select shale samples with different maturity levels to prepare water balance shale samples;
[0036](2) Place the water-balanced shale sample in the pressure-resistant sample cylinder (denoted as SC) of the volumetric adsorption device;
[0037](3) Under the conditions of adsorption temperature of 80°C and adsorption equilibrium pressure of 30 MPa, use the principle of volumetric method to determine the amount of pure carbon dioxide adsorbed by shale samples;
[0038](4) Simultaneously inject nitrogen dioxide and carbon dioxide into the pressure-resistant reference cylinder (denoted as RC) of the volumetric adsorption device at a molar ratio of 1:100 to obtain a uniform mixture of nitrogen dioxide and carbon dioxide; After the reference cylinder...
