Potential Techniques for Conversion of Lignocellulosic Biomass into Biofuels

Abstract

Lignin has been found as a naturally available aromatic resource for biofuel production. Reduced reliance on fossil fuels and replacement with a green and environmentally friendly strategy are currently one of the most pressing challenges. There has been significant growth in energy consumption, necessitating the transition to an alternative energy source. The current renewable energy source has significant biofuel production potential. It is critical to discuss the process parameters for pinpointing lignin content as part of the technology development process. Biofuel
production possesses various challenges that need to be addressed. In this research, we precisely discussed the numerous lignin conversion mechanisms that can boost the biofuel output. Catalytic deoxygenation is a fuel promotion process that decreases the oxygen content, which causes
instability and corrosion. SiO₂, ZrO₂, CeO₂, TiO₂, and Al₂O₃ are used in catalytic deoxygenation to produce biofuel. The use of chosen Al₂O₃-TiO₂ metal oxide catalysts is critical in biofuel production. To obtain hemicellulose levels, two-step pretreatments with alkali and acids are used.
The constraints, challenges, industrial perspectives, and future outlooks for developing costeffective, energy-efficient, and environmentally friendly procedures for the long-term valorization of lignocellulosic materials were examined in the conclusion
