II. How is CBM formed
Coalbed methane (CH4) forms in one of two ways. During the earliest stage of coalification (the process that turns plant detritus into coal), biogenic methane is generated as a by-product of bacterial respiration. Aerobic bacteria (those that use oxygen in respiration) first metabolize any free oxygen left in the plant remains and the surrounding sediments. In fresh water
Coalbed methane is a form of natural gas that is trapped within coal seams.
In recent decades it has become an important source of energy in United States, Canada, and other countries.
It is called sweet gas.
Enhanced coal bed methane recovery
is a method of producing additional coalbed methane from source rock.
This technique may be used in conjunction with carbon capture
and stora

1. 애기장대와 그 유전자
애기장대는 십자화과의 두해살이풀로 학명은 Arabidopsis thaliana이다. 높이 15~35㎝이다. 뿌리잎은 모여나고 거꾸로 된 피침모양이며, 줄기잎은 피침모양에 잎자루가 없다. 4~5월에 작고 하얀 꽃이 총상꽃차례로 줄기 끝에서 핀다. 열매는 견과이다. 우리나라에서
about 10-15 percent higher methane (CH4) content than normal landfill gas.
Amount of organic waste is approximately 8,300tons/year by 2008 and 2007, among which only about 7% (6.1million tons/year) are used to source of energy (biogas).
Bio-gas produced by using organic waste were used mostly as a heating fuel of the digestion tanks or power plant fuel.
regulating the amount of carbon dioxide emission is obliged to many already developed countries under the name of Kyoto protocol. It is unavoidable for Korea as well to join the Kyoto protocol in the near future. MB government therefore conducts the “Low carbon green growth” policy to participate in trend of reducing emission of carbon dioxide.
