3 Terms and Definitions
GB/T 23251 define the terms and definitions section and the following terms and definitions apply to this document.
3.1
Direct coal liquefaction coaldirectliquefaction
Coal under the action of high pressure, high temperature and the hydrogenation reaction catalyst with hydrogen, whereby liquid fuel directly into the process.
[GB/T 23251-2009, the definition 3.8]
3.2
Oil coal slurry coal-oil-slurry
By a certain size of pulverized coal with solvent oil, mixed catalyst made of a uniform, stable suspension.
3.3
The apparent viscosity of oil - coal slurry apparentviscosityofcoal-oil-slurry
Oil coal slurry apparent viscosity at a shear rate of 100s-1 under the oil viscosity is called coal slurry with η100s-1, the unit is
MPas (mPa · s).
4 Method summary
Amount of oil loaded coal slurry in coaxial cylinder type rotational viscometer outer cylinder, under specified conditions, the inner tube at a constant angular velocity,
By measuring the inside at a shear rate of 100s-1 during the rotation of the cylinder suffered viscous torque, with a pre-certified reference material viscosity calibration curve
The apparent viscosity of oil - coal slurry results.
5 Reagents and materials
Viscosity certified reference materials. 4, dynamic viscosity range 0mPa · s ~ 10000mPa · s (20 ℃).
