Abstract Scope |
The clean utilization of low-concentration gas is of great significance to improving energy utilization efficiency, mitigating the greenhouse effect and achieving dual carbon goals. In this paper, using the principle of displacement chromatography, an adsorption separation method for recovering methane gas in low concentration gas (≤30%) was developed. Using 5A molecular sieve as an adsorbent, the molecular structure of 5A molecular sieve was characterized by X-ray diffraction spectrum, infrared spectrum and scanning electron microscope. The change law of separation and enrichment of low-concentration gas under the conditions of different volumes, different concentrations, different carrier gas velocities and different column diameter ratios was studied. The research results show that: when the feed gas concentration increases within a certain range (10%~30%), methane can be enriched to 2 to 3 times the original (25%~76%) in one step, and the recovery rate increases slightly and stabilizes. Around 30%. |
