H2-Rich and Tar-Free Downstream Gasification Reaction of EFB by Using the Malaysian Dolomite as a Secondary Catalyst

In this study, Malaysian dolomites as secondary catalysts are placed at the downstream of fluidized-bed gasifier. Three types with different elemental ratios CaO-MgO content denoted P1, P2, and P3 investigated EFB gasification reaction cracking temperatures (700–900 °C). The performance a variation catalyst to biomass weight ratio (C/B) (0.05 0.30 w/w) is evaluated. findings showed that total gas yield increased by 20%, hydrogen 66%, along an almost 99% reduction in tar P1 following conditions: temperature 850 °C, equivalence (ER) 0.25, 900 °C. Malaysia dolomite could be provide better alternative, tar-free hydrogen-rich possibility regeneration re-use.
