Biology may be key to coal-to-gas conversion

Aug 23, 2019 · "Coal is a big molecule and some of the bacterial species can break it down into smaller molecules and then even smaller compounds like ascetic acid, carbon dioxide and volatile fatty acids," Liang explained. "And from there, certain archaea species can convert those smaller molecules into methane." "It's a simple process.

Coal - Structure and properties of coal | Britannica

Coal - Coal - Structure and properties of coal: The plant material from which coal is derived is composed of a complex mixture of organic compounds, including cellulose, lignin, fats, waxes, and tannins. As peat formation and coalification proceed, these compounds, which have more or less open structures, are broken down, and new compounds—primarily aromatic (benzenelike) and hydroaromatic ...

Carbonisation, or charring, is a process by which fossilised compounds become coal. In the process of this long-term geochemical change, plant material (cellulose and lignite) are transformed into peat, then to brown coal, hard coal and anthracite. One of the prerequisites for carbonisation is a large amount of matter containing carbon.

What is chemical energy? - eschooltoday

Note that energy is often needed to break up bonds before forming new bonds. Example: during photosynthesis, energy from the sun is needed/used to break the CO2 and H2O bonds. Glucose is produced and O2 bond is formed as a result. Batteries, biomass, petroleum, natural gas, and coal are examples of stored chemical energy.
