Ultra-filtration (UF) provides a new way of generating narrow bands of sample in the fractionation of coal and petroleum-derived liquids. It allows larger quantities of high-mass fractions to be recovered, making more detailed investigations possible, through the use of techniques requiring larger ...

(to a reflectivity of almost 0.5 and near the boundary between subbituminous and high-volatile Cbituminous coal), hydrocarbon generation produces chiefly methane. The maximum generation of liquid petroleum occurs during the development of high-volatile bituminous coals (in the reflectivity range from ...

1 We also study the effect of a boom and bust in the coal industry during the 1970s and 1980s on welfare receipt and family structure in the coal-producing regions of rural Appalachia. During the 1970s, the Organization of Petroleum Exporting Countries (OPEC) oil embargo drove up the ...
petroleum, coal may be more hydrophilic; relative to water it is clearly hydrophobic and not readily wetted by water. This is particularly true for freshly ground coal which has surfaces which have not been altered by air oxidation. In the absence of surfactants, coal particles do not easily ...
