Abstract

1500876 Treatment of crude tar TOMOE ENG CO Ltd 22 June 1976 [30 June 1975 2 Feb 1976] 25900/76 Heading C5E Crude tar produced as a by-product in the dry distillation of coal is treated by separating by settling into ammonia water, tar and carbonaceous powders containing tar adhered thereto, adding water and optionally oil to the tar-containing carbonaceous powders, stirring the mixture to liberate tar from the powders and at the same time to disperse in the water the liberated tar, optionally dissolved in the oil, allowing the mixture to settle into an upper layer of tar or tar dissolved in oil, a middle water layer and a lower tar-free carbonaceous powder layer and recovering the tar and the tar-free carbonaceous powders. The water added to the tar-containing carbonaceous powders may be the ammonia water which settles out in the first stage. The carbonaceous powders so produced may be neutralized as raw materials for dry distillation by mixing with pulverized coal.
