| titleOfInvention | Method of desulphurizing coal |
| abstract | 1512063 Desulphurizing coal TUNG-YU CHIA 6 May 1975 [9 May 1974] 18909/75 Heading C5G Coal is desulphurized by immersing powdered coal in an aqueous solution of a polar compound, washing the powder with water after taking out of the solution and drying, the polar compound being selected from (a) an alkyl sulphate R-OSO 3 M (b) an alkyl sulphonate (i) R-SO 3 M or (c) an alkylarylsulphonate (d) an α-sulphonated fatty acid (e) an α-sulphonated fatty ester (f) a dialkyl-sulpho-succinate (g) a fatty acyl benzimidazoline (h) an N-alkyl amide sulpho-succinate (i) a polyoxyethylene alkyl ether (j) a polyoxyethylene alkylphenol ether (k) a di-alkyl ester of polyoxyethylated malic acid (1) a polyoxyethylene alkylamine (m) an alkylpyridinium halide (n) an alkyl phosphate (o) an alkylaryl phosphate (p) salts of fatty acid CH 3 -(CH 2 ) n -COOM (q) sodium oleylmethylaminoethane sulphonate (r) sodium dibutylnaphthalene sulphonate (s) sorbitan monolaurate polyglycol ether and (t) oleyl sarcoside wherein each of R and R<SP>1</SP> is an alkyl group having from 10-20 carbon atoms, M is selected from NH 4 and alkali metals, X is a halogen and n is an integer from I to 10. |
