Preparation of α-FeOOH with different crystallinity and its low-temperature desulfurization performance.

Crystal α-FeOOH and amorphous α-FeOOH were obtained at different preparation temperatures, and low temperature desulfurization tests were carried out respectively. The results were characterized by XRD, BET, FT-IR and UV-vis. When the preparation temperature is 10-20℃, α-FeOOH is a crystalline structure composed of large grains, and when the preparation temperature is -5-5℃, α-FeOOH is an amorphous structure composed of small grains.
