Abstract

1489690 Briquetting coal COAL INDUSTRY (PATENTS) Ltd 25 May 1976 [4 July 1975] 28255/75 Heading C5G Coal is briquetted by (a) heating a low rank weakly caking high volatile coal in fine particulate form in oxygen at a temperature below the temperature at which substantial swelling of the coal normally occurs and for a time such that the property of the coal to swell during a further heating step to above the normal swelling temperature is reduced, (b) subjecting the coal from (a) to 600‹ to 900‹ C., (c) mixing the heated coal with a caking coal so that the mixing temperature is 400‹ to 500‹ C. and (d) briquetting the mixture without the addition of binder and without substantial drop in temperature. Step (a) may be effected in a fluidized bed using air as a fluidizing medium.
