油页岩半焦燃烧动力学研究
Combustion kinetics study of oil shale semi-coke
摘要
Abstract
Combustion kinetics is the basis for studying the combustion characteristics of oil shale semi-coke particles. Thermal gravimetric analyzer (TGA) was used to conduct isothermal combustion experiments of oil shale semi-coke. Effects of combustion temperature and oxygen concentration on kinetics of oil shale semi-coke combustion were analyzed. Higher combustion temperature and oxygen concentration would lead to faster combustion rate. A kinetic model considering oxygen concentration effects was developed. It was found that the combustion rate of oil shale semi-coke is proportional to oxygen concentration to the 0.97 power. The kinetic model yielded good agreements with the experiments results, and could provide a base for further investigation on the combustion of large oil shale semi-coke particles.关键词
