K. W. Brodlie,J. R. Gallop,A. M. Mumfordyed a prominent role in research and development programmes. Although extensive, however, the literature on coal utilisation economics is often not particularly helpful because of differences in the economic conventions and design ground rules used by different authors.

Scientific Visual Representations in HistoryDuring the 1960s and 1970s, a growth in the public awareness of, and interest in, the environmental effects of industrial activities was evident. As a result, coal utilisation practices have come under closer scrutiny and there has been a trend towards increasingly severe controls almost everywhere.

Liquefaction,Coal and oil belong to the family of fossil fuels which also includes natural gas, oil shales, tar sands and peat. Although all fossil fuels may be broadly regarded as hydrocarbon compounds, there are significant chemical differences which, in particular, determine the possible approaches to coal liquefaction.
