摘要：Coal-oil slurry preheating is an important step during coal direct liquefaction, and some physical and chemical changes will occur that will affect the viscosity of coal-oil slurry. The project is necessary for the building coal direct liquefacation demonstration plant and has a good application prospect. A rotary viscometer that can measure the viscosity of coal slurry at high pressure-high temperature was designed by self and manufactured in this project. Three kinds of crushed coal including Yanzhou Coal (middle rank and caking), Shenhua Coal (low rank and non-caking) and Shengli Coal (brown coal) were used, and anthracene oil was used as the hydrogen-donating solvent. The coal-oil slurry is prepared by mixing the anthracene oil with the coal powder (
