A comparative study of experimental maturation of peat

Brown coal samples with R o = 0.29% (Yao et al., 2006) were heated under the same experimental conditions simultaneously, providing the quantitative reference standard of thermal maturation. The

A comparative study of experimental maturation of peat

Laboratory experiments were performed on a peat, a brown coal, and a subbituminous coal using closed-system pyrolysis. The samples were heated isothermally for 48 h from 150 to 500 °C. All three samples had similar pathways of thermal evolution, which can be divided into four phases based on vitrinite reflectance (Rm).

Peat and Peatification, Coal, Kentucky Geological Survey

Sep 18, 2019 Peat is soil-like, partially decayed plant material that accumulates in wetlands. Most people learn that coal is formed in swamps, but this is not completely accurate. The term “swamps” can be applied to many different types of wetlands, but coal only forms from peat-accumulating wetlands. Hence, peat deposits form in wetlands, but not all
