PROCESS FOR OBTAINING LOWER MOLECULAR WEIGHT MATERIALS FROM COAL |
摘要 |
Coal of low degree of carbonisation is converted into low-molecular products by treatment with a liquid which contains a polar organic liquid as the main constituent. The treatment is carried out at elevated temperatures and pressures in the absence of a catalyst and reducing gases. The liquid is then separated from the converted coal. |
