Kinetics of desulfuration product sulphoaluminate calcium GUO Huiling 1, a, XIE Junlin 2,b 1,2 Key Laboratory for Materials Science and Engineering of Ministry of Education Wuhan University of Technology, Wuhan, China a emai: guoguo0302@126.com, bemail: xjlclxy@126.com Keywords: coal desulfurization; high-temperature phase; sulphoaluminate calcium; kinetics Abstract: The formation kinetics of sulphoaluminate calcium was studied by variations of sulfur release with time from SC-132 based on competitive reactions, the generation of sulphoaluminate calcium and the decomposition of CaSO4.
According to the sulfur released from analytical reagent CaSO4, the curve on the decomposition rate (dm/dt) with the remaining mass (m) was obtained, thus calculating the instantaneous molality of calcium sulphoaluminate in the raw materials by theoretical derivation.
