Abstract

1298175 Desulphurizing coal and coke TRW Inc 19 April 1971 [24 Feb 1970] 23255/71 Heading C5G Pulverized coal, lignite, charcoal or coke, is desulphurized by treatment with an organic acid, followed by separation of the acid from the coal. The treatment may be carried out at a temperature in the range - 20‹ to 200‹ C. and a pressure in the range atmospheric to 500 p.s.i. The acids used are one or more of o-chlorophenol, p-chlorophenol, nitrophenol, and o-cresol. The process for the removal of organic sulphur compounds is illustrated in Fig. 1 which includes optional pyrite removal at 16 and a nitrogenreducing step at 17.
