ABSTRACT

A differential thermal analysis of the process of preliminary prepared rice husk (PPRH) thermal treatment was conducted. The phase composition of the SiO2 samples was investigated and the dispersed composition of SiO2 and PPRH powders obtained as a result of PPRH thermal treatment was studied. The procedure mechanism and kinetic constants of the reactions of thermal transformation of PPRH into silicon(IV) oxide were offered. A mathematical model of the process of obtaining silicon(IV) oxide and thermal energy out of PPRH was developed which includes equations of the transformation kinetic of PPRH into SiO2, heat and mass exchange and also equations of gas dynamics. The process was explored in the mathematical model.
