Certain generalizations regarding the behavior of group components of shale oil in thermal processing, on the basis of derivatographic analysis
- Scientific-Research and Technological Institute, Sofia (Bulgaria)
Derivatographic analysis is a frequently used method for obtaining supplementary information on the structure, structural changes, and processes taking place in thermal processing of substances. It is also extensively in studying solid fuels. The work reported here was aimed at studying the changes taking place under the conditions of derivatographic analysis in the group components of the residue (distilling above 350{degrees}C) from the liquid product obtained after thermal breakdown of Bulgarian oil shales in a unit with a solid heat-carrier. The group components - oils, resins, and asphaltenes - were obtained by separating the residue by means of procedures given. The derivatographic studies were performed in Paulik-Paulik-Erdey MOM apparatus in an inert medium with a heating rate of 6{degrees}/min, and DTA 1/10, DTG 1/10, and TG 1000 mg. 8 refs., 3 figs.
