“…As the CHC production temperature was further raised to 900 °C, the surface area of CHC decreased to 0.18 m 2 g -1 . This was because when the temperature was too high, the microporous structures started to be sinter [34]. The SEM images of CHCs were used to verify this.…”

Sulfur Transformation during Coal Pyrolysis with Char Heat Carrier

et al. 2023

To investigate sulfur transformation during coal pyrolysis with char heat carrier (CHC), the effects of temperature, CHC/coal, and CHC production temperature were explored in a fluidized bed. The yield rates of sulfur in H2S () and YCOS elevated with temperature. and Ychar‐S decreased, and temperature showed no significant effect on Ytar‐S. CHC inhibited sulfur transformation to the gas phase. More H2S and COS were fixed in mixed‐char in form of CaS by CHC, resulting in the increase of Ychar‐S. CHC was favorable for CH3SH decomposition. The inhibitory effect was enhanced with increasing CHC/coal. Higher production temperature inhibited the sulfur fixation capacity of CHC. CHC enhanced the decomposition of pyrite, organic sulfur, sulfate, and the yield of sulfide in mixed‐char.
