Gas extraction of coal |
| abstract |
Process for the gas extraction of soluble constituents of coal which comprises heating the coal in the presence of an extractor to a terminal temperature of 400 DEG C. to 550 DEG C. where the extractant at the terminal temperature is in the gas phase to extract the soluble constituents from the coal and separating the extractant from the residue and recovering the extract from the extractant. The heating of the coal in the presence of an extractant is at an initial rate of 20 DEG C. per minute and preferably as fast as possible to an initial temperature of 370 DEG C. to 390 DEG C. preferably 380 DEG C. and thereafter heating the coal to a terminal temperature at a rate not more than 20 DEG C. per minute and preferably below 5 DEG C. per minute thereby minimizing secondary repolymerization reactions. |
