Moreover, a reduced Ni content of 5 wt% was used and different operating variables (temperature, steam excess and presence of H2, CO2, CO and CH4) were studied. It was confirmed that regardless the variations in the composition of the gas entering the reforming reactor, the conversion of toluene (used as tar model compound) was complete at 700 ºC and high space velocities (ca. 90000 h−1 with respect to total gas and ca. 5 kgtoluene/kgreduced cat·h) with minimal coke deposition. In addition, reaction-regeneration cycles were conducted under different regeneration temperatures and gas mixtures for the removal of the deposited solid carbon. Finally, the catalytic activity of this novel catalyst was tested against several commercial catalysts at 700 ºC, demonstrating the superior performance of the 5 % Ni-mayenite/CaO compared to any of the Ni-based commercial catalysts studied.This work has received funding from project TED2021–131768B-I00 funded by MCIN/AEI/10.13039/501100011033 and by the “European Union NextGenerationEU/PRTR”.
