WebJul 21, 2024 · Uses of Coal Bed Methane (CBM) The various uses of coalbed methane are as follows: It is employed in the manufacturing of cement, methanol, and other products. Both rolling mills and steel companies use it. CBM is also used as compressed natural gas (CNG) auto fuel. It can serve as a fertiliser’s raw material. WebAn extensive experimental investigation about the process of desorbing methane by adsorbing carbon dioxide in real coal samples was performed. The proof of principle and the technical feasibility of the method could be verified with these measurements. These research results indicate that CBM can become an alternative to conventional natural gas.
WebApr 2, 2024 · June 2015. Coal bed methane (CBM) is one of the unconventional energy sources which many countries have been started to be explored seriously and coal bed methane is kind of renewable energy. CBM is notably different from a typical conventional gas reservoir, as the methane is stored within the coal by a process called adsorption. WebCoal bed methane is considered an unconventional gas as it is held tightly in reservoirs and it requires special stimulation and technologies to produce it economically.
