dolomitic and volcanic. The presence of volcanic sediment makes dolomite more resistant to weathering and endows it with hardness [14–16]. However, it was found that the use of dolomite in its raw form could not improve the mechanical properties of the polymeric matrices. This is because dolomite particles easily agglomerate, while their ...
Despite the high catalytic activity, the poor mechanical properties of dolomite restrict its use in circulating fluidized bed reactors since it gets easily crushed (Meng et al., 2018). Olivine, another mineral catalyst composed mainly of (Mg, Fe) 2 SiO 4 has Fe as the active element for the cracking of biomass tar. The addition of metals such ...
