RESEARCH AND EXPERIMENTAL PROCESSING OF HIGH-SULFUR OIL SHALES

During the retorting process of oil shales in Fischer retorts sulphur is transferred to retorting products (to oil, gas or semicoke) in diff erent proportions, depending on the content of organic sulphur (more p recisely on the share of organic sulphur in total one) in the shales. The conditions of retorting the shales do not influence the sulphur co ntent in the retort oils. High-sulphur oils obtained in the experiment al retort are similar to each other in their chemical group compositio n. They are characterized by an increased content of aromatic hydrocar bons and a reduced content of phenols and alkenes.
