Abstract
Notice of Retraction
After careful and considered review of the content of this paper by a duly constituted expert committee, this paper has been found to be in violation of IEEE´s Publication Principles.
We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper.
The presenting author of this paper has the option to appeal this decision by contacting TPII@ieee.org.
The experimental study and safety analysis was carried out on low concentration coal bed methane enrichment by PSA based on the explosion triangle. The results show that the traditional PSA approach of using single adsorbent probably makes methane concentration very close to the explosion limit and may result in explosion risk in the adsorption process, when the methane concentration in coal bed methane is blow 30%. A new method was brought forward for low concentration coal bed gas safe enrichment with the use of both actived carbon and CMS as adsorbents, so that methane and oxygen in low concentration coal bed gas can be adsorbed simultaneously. The concentration of CH4 and O2 can be controlled well and will not exceed the explosion limit in both adsorption and desorption process.
