โœฆ Synopsis

01 Solid fuels (preparation) a sludge, onto coal surface. Treatment of coal may also be carried out by oxidation of Fe*+ in the wastewater to Fe3+ prior to addition of the crushed coal, followed by increase of pH to 2-5 for deposition of Fe (III) compound onto coal surface. Gas oil is obtained at high yield in gasification of coal, manufacture of tar, char, etc.

The gradual changes in weight, in elementary composition, in content of oxygen functional groups and in spin concentration have been established for samples of black coal, brown coal and lignite heated in air for a maximum of 1200 h. An intensive oxidative dehydrogenation was found to occur after mo
