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.
