· The / of methane and multi-component gases in the deformed coals is not consistent with primary coals, which form an effect of hysteresis in different kinds of tectonically deformed coals. With the change of pore structure of tectonically deformed coals at reservoir condition, the added adsorbed CH4 in the

a Introduction - 1 Background and purpose. The of chemicals to sediments and soils is an important that affects a chemicals distribution in the environment. If a chemical is adsorbed to soil particles, it will remain on the soil surface and will not reach ground water.If a chemical is not adsorbed, it will leach through the soil profile and may reach ground waters and
