A high-frequency furnace was utilized to carry out rapid pyrolysis of Shenfu coal. The effect of temperature and residence time on the properties of solid and gas products was studied. The results show that the mass loss and true density of the char increase with increasing of both temperature and time. The analysis of their infrared spectra indicates that the hydrogen/oxygen functional groups decompose to form H₂, CO, CO₂, CH₄ and other gases during pyrolysis, and the decomposition increase with increasing temperature and time. The emission of H₂ and CO monotonically increases, however there are emission peaks for CO₂ and CH₄. The total gas products increase with temperature and time, leading to the pores and cracks on the char after high temperature pyrolysis.
