GB/T 23251 coal chemical coal Technical Guidelines3 Terms and DefinitionsGB/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 summaryAmount 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 materialsViscosity certified reference materials. 4, dynamic viscosity range 0mPa · s ~ 10000mPa · s (20 ℃). ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 30045-2013_English be delivered?Answer: Upon your order, we will start to translate GB/T 30045-2013_English as soon as possible, and keep you informed of the progress.
