Abstract

The invention relates to a gas energy storage strengthening method based on porous material absorption in the technical field of gas compression and storage. The gas energy storage is strengthened by adding a chromium oxide adsorbent or silicate porous material adsorbent into a gas storage tank and charging 5-20 atmospheres of gas, wherein the addition of the adsorbent is 30-100 percent of the total capacity of the gas storage tank. The invention has twice gas absorption quantity than that without using the porous material; and because the self weight of the porous material is light, which influences the self weight of the gas storage tank a little, the increased compressed air energy can be fully utilized to push an engine to operate.

Description

technical field [0001] The invention relates to a method in the technical field of gas compression storage, in particular to a gas energy storage enhancement method based on porous material adsorption. Background technique [0002] As energy shortages and climate change are increasingly affecting human life and survival, the development of clean energy that can replace petroleum has become a real challenge for mankind. Driven by the energy stored in compressed gas, it is a development direction in the field of new energy and has received extensive attention. This compressed air-driven pneumatic engine can greatly save energy, and the engine exhausts air, which can truly achieve zero emissions, and has great advantages in environmental protection. This technology also has the advantages of low cost, less investment, and long service life. It is a high-end technology in line with my country's energy strategy policy, and it is a great project that benefits mankind. However, o...
