Measurement of physical properties of coal liquids under process conditions
Instrumentation has been developed for measurement of physical properties (viscosity and density) of coal liquids and slurries under conditions typical of those found in coal liquefaction processes such as SRC, H-Coal, and EDS. The instruments are being operated in a flow system designed for slurry rates up to 1 g/s at 810 K and 31 MPa pressure. A capillary tube viscometer and a Norcross falling ring viscometer are used for viscosity measurement. Thus far rheograms (shear rate vs shear stress diagrams) have been determined for 35 wt % Illinois No. 6 coal (-170 mesh) in SRC-I recycle solvent at 13.9 MPa (2000 psig) for the temperature range of 400 to 700 K. A commercially available gamma radiation absorption instrument has been modified for the operating conditions required and is being used for density measurements. Instruments for measurement of thermal conductivity and heat capacity of coal liquids have been designed for future installation in the facility.
