L-CLCTM is based on using calcium-based sorbents as precursors for CaSO4 formation, which is used as an oxygen carrier. Its principle lies in the in-situ sulfur retention process performed in fluidized bed combustors burning solid fuels with high sulfur content. The target redox pair for the oxygen transference to the fuel is CaSO4/CaS. In this research work, experimental tests burning CH4, syngas and H2 with a moderate H2S concentration were conducted in a continuous CLC unit. This experimental campaign is first in a kind as there is hardly information about the CaSO4/CaS pair for the L-CLCTM process. High combustion efficiencies were achieved at moderate temperatures (800–850 °C) when burning H2 and syngas (∼96–99 %). Likewise, low CH4 combustion efficiency (∼59 %) was found even operating at a temperature as high as 945 °C. Additionally, experimental tests at different Ca/S molar ratios were performed. They revealed that it was possible to reach suitable sulfur retention values (∼82 %) by using a Ca/S molar ratio of 2.25. This value resulted in a very feasible ratio since it is commonly used in fluidized bed combustors.This work was supported by the SWINELOOP project (PID2019-106441RB-I00 funded by MICIN/AEI/10.13039/501100011033).
