Recently, biomass gasification process has gained lots of attention because of sustainable energy sources utilization. Being renewable energy source, biomass can serve as a viable replacement for fossil fuels. The process gasification is the conversion of organic substance via thermochemical process where syngas is produced along with the solid product termed as char. Such process is also well known for the generation of heat and power and synthesize the second-generation biofuels and hydrogen production. Unfortunately, tar formation in gasifiers during biomass gasification remains a main problem to commercialization. In the current review we focus at recent advancements in catalytic biomass gasification about supercritical water catalytic gasification (SCWG), catalytic steam gasification and catalytic CO 2 gasification, and discuss on gasification process, parametric impact, biomass-pretreatment and catalytic deactivate mechanism in order to overcome the challenges and improve the catalytic yield. Future direction and critical prospective of catalytic biomass gasification are also discussed in this review. [Display omitted] • The current energy sector's reliance on fossil fuels contributed to global warming through CO 2 emissions. Therefore biomass becomes prominent as an alternative energy source due to its eco-friendly nature. • The efficiency of biomass gasification process to value-added products as sustainable and renewable energy has been greatly improved due to the addition of catalysts. • Steam gasification, CO 2 gasification and supercritical water catalytic gasification (SCWG) have been reviewed in present study.
