Abstract:

A new carbide slag(CS)seriflux utilization was proposed. The flue gas from a coal-fired plant was first bubbled into CS seriflux for CO₂ capture. The obtained carbonated carbide slag seriflux(CCSS)was dried and utilized as a CO₂ sorbent in the calcium looping cycles. The CO₂ capture behavior of the dried CCSS and the raw CS was investigated in a dual fixed-bed reactor and a thermo-gravimetric analyzer. The effects of carbonation time, calcination temperature and carbonation temperature on CO₂ capture performance of CCSS in the multiple carbonation/calcination cycles were studied. The results show that the CO₂ capture capacity of CCSS was higher than that of CS. Calcined at 950 ℃, CCSS shows better carbonation reactivity than CS, which benefits CO₂ capture under severe calcination conditions. In the range of 700 to 725 ℃ for the carbonation, CCSS shows the optimal CO₂ capture performance. The calcined CCSS shows better porous microstructure than the calcined CS. The calcined CCSS exhibits a larger surface area and pore volume in the cycles, which favors a higher CO₂ capture capacity in the multiple cycles.
