Abstract

The devolatilization characteristics of Wangqing oil shale were studied in a laboratory-scale fluidized-bed unit at 600–904 °C. The characteristics of furnace temperature variation, preheating time and burnout of particles were studied in detail after oil shale being injected. The effect of batch mass, bed temperature, fluidization velocity, and moisture content on volatile combustion was also investigated. The experimental results show that the combustion of volatiles was mostly influenced by the bed temperature and reaction mechanism. The combustion time was in accordance with empirical model. A new modified model for combustion time of volatiles related to temperature, particle size, and reaction mechanisms was proposed. The results calculated with this model are in agreement with experimental data, and it can be used to predict combustion time of volatiles for the high-temperature region.
