Dolomite impregnated with NiO and calcined with CaO and MgO is an efficient catalyst for the upgrading of syngas into hydrogen-rich and tar-free combustible gas (Varjani, 2022; Zeng et al., 2018). Combining dolomite with Ni- and Fe-based metal catalysts can boost the tar conversion efficiency and subsequent H 2 production (Varjani, 2022).
