摘要

采用高温热台显微镜原位研究了气化温度和颗粒粒度对石油焦气化反应的影响，并对比了神府烟煤和石油焦的反应特性。研究发现，石油焦在气化过程中颗粒收缩，表面结构发生变化，反应速率的改变由低温下逐渐减小，到高温下1300℃时先增大后减小。相同转化率下，反应时间随温度的升高而减少，随颗粒粒度的减小而减少。对比神府煤焦和石油焦的气化反应发现，石油焦反应活性低，为神府烟煤焦平均气化反应速率的1/6。

Abstract

In-situ heating stage microscope was applied to analyze the influence of temperature and particle size to the gasification characteristics of petroleum coke. The differences of reaction characteristics between bituminous char and petroleum coke were also analyzed. It was found that the particle shrank during the gasification process

and the surface structure of petroleum coke was changed. The reaction rate decreased with reaction time at the lower temperature (below 1300℃)

while first increased and then decreased at 1300℃. Besides

under the same conversion rate

reaction time increased with the temperature and the decrease of particle size. The gasification reaction rate performed different characteristics at 1300℃

owing to the change of particle structure. The comparison of the gasification reaction between bituminous char and petroleum coke showed that the average gasification reaction rate of petroleum coke was 1/6 of bituminous char.
