Development of measurement system for continuous monitoringsystem for gas generation behavior during coking process

摘要

A new monitoring system for gas generation behavior during cokingreaction has been established. Coal sample in nitrogen flow was heated with an electricfurnace, and generated gas was lead to Fourier-transform infrared spectroscopic analyzer anda gas sensor for hydrogen with nitrogen gas carrier. This method has a good time-resolved ofsecond order, so that a short time reaction of coal pyrolysis can be monitored continuously.Using this system, different gas profiles on coking reaction of two coals with oppositecharacters could be obtained.
