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
water, those free complex carbohydrates turned into fermentable sources through pre-treatment process - saccharification. Then, it can be changed ethanol form through fermentation by yeast or genetically engineered E.coli and we can produce biofuel from that ethanol. Now, the way of decreasing process and cost are studied from a few researchers. So we will show the whole process of the production

초등 교육은 지식 교육보다 인성 교육을 더 강조하고 있고, 따라서 초등 교사의 요건에 관한 논의도 인성적 측면에 큰 비중을 두어야 하겠으나, 초등 영어는 영어로서의 의사소통에 대한 기능이 무엇보다 중요하므로 김진철이 강조한 초등 영어지도 교사의 요건에 대해 언급하고자 한다.

water and returns to the original substance; water after being used. We can expect that after 2010, the cost of hydrogen as one of the resources should be lower than that of fossil fuel. Fuel cell is the bright prospective technique and it already spreads out in many industrial field like hydrogen fueled car. However, although our interest in fuel cell is increasing, the stage of the development
What is Bioenergy?
Bioenergy is renewable energy made available from materials derived from biological sources. Biomass is any organic material which has stored sunlight in the form of chemical energy. As a fuel it may include wood, wood waste, straw, manure, sugarcane, and many other byproducts from a variety of agricultural processes.
So, Why do we produce Bioenergy?
One reason governments

1. The Necessity of the Study
1.1 . Natural Disasters in Korea on the Rise
Humankind in modern society has been leading an affluent life by virtue of the rapid scientific progress. However, we are never safe from natural disasters such as a typhoon and an earthquake which are powerful enough to bring it down.(A Research on the Actual Condition of the Victims of Natural Disasters in Korea and
Sulfur Dioxide(SO2)
The release of SO2 to the atmosphere is the primary cause of acid rain in the world.
Fossil fuel combustion at electric power-generating plants accounts for about70% of
the emissions.
Coal, Oil, and all other fossil fuels naturally
contain some sulfur.
Volcanic eruptions are another more localized natural source of SO2
SO2 + OH. HSO3.

Digestion tank production gas is a biogas produced by artificial anaerobic digestion of organic wastes with bacteria in the digestion tank. This can be divided into mergence gas which produce bio-gas by putting more than two of them together, among the organic waste gas, waste water gas, livestock· sewage gas, sewage sludge gas, depending on the type of organic waste. Because they are artificial
Definition : technology of capturing CO2 from large point sources and storing it.
Processes of CCS
- Capture
- Compressing and Transport
- Storage
Biomass is any organic material which has stored sunlight in the form of chemical energy.
