PROCESS FOR REMOVING PYRITIC SULFUR FROM BITUMINOUS COALS

摘要

the process described, which is used to extract the pyritic sulfur and reduce the amount of ash in the bituminous coal is to crush the coal source (11, 21), to a micro area (14, 24) by means of a liquid preparation containing a bridge only heavy oilto separate the micro agglomerates and separated by washing with water to remove pyritic sulfur suspension (17, 18, 29, 30). in one embodiment, the coal is subjected to a second phase of microwave sintering (27).
