Study on Blank Roasting Process and Kinetics of Power Generation Ash from Vanadium Phosphate Ore AITranslate
Abstract AITranslate
The blank roasting process and kinetics of power generation ash from vanadium phosphate ore were studied.The results show that in the ash,vanadium mainly exists in the form of vanadium mica,predominately in the V3+.The optimum process parameters for the blank roasting of the ash are as follows:grinding 90%of the ash to a fineness of-0.074 mm before roasting and then roasting the ash at 880~900℃for 16 h,the leaching rate of V2O_5 reaches approximately 71%.The blank roasting of the ash is controlled by interfacial chemical reaction,with an apparent activation energy of 89.75 kJ/mol and a kinetic equation of 1-(1-x)1/3=114.47exp[-89750/(RT)]t.
