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
unstable compared to general fuel cell.
The need for MBFC
Waste processing caused sludge reduction.
Energy saving by generation of electron power
Technology leadership of first stem form development
Non-combustibility.
( Diesel – 63℃ Biodiesel – 150℃ )
Net COx output is very low.
Biodegradability is very High.
( Degradable 90% in 3 weeks. )
High-temperature decomposition
High-temperature splitting of water occurs at about 3000 °C. At this temperature, 10% of the water is decomposed and the remaining 90% can be recycled. To reduce the temperature, other processes for high temperature splitting of water have been suggested:
▸Thermo-chemical cycles.
▸Hybrid systems coupling thermal decomposition and electrolytic
