Summary: Biofuels are sustainable, eco-friendly, and bio-economic alternatives to fossil fuels. They are classified into different generations based on production methods, cost-effective technology, and substrate used. While first and second-generation biofuels have limitations, third-generation biofuels show promise as environmentally friendly alternatives. Challenges still remain for commercialization, leading to the development of fourth-generation biofuels using innovative techniques. Further research and development are needed to overcome these challenges and pave the way for a sustainable bioeconomic pathway in the fuel industry.

Summary: The purpose of this study is to investigate the operating conditions of a physicochemical pretreatment process for lignocellulosic biomass using homogeneous acid catalysts. Four parameters were examined: moisture content, acid catalyst, type of biomass, and reactor morphology. Different types of biomass were processed with sulfuric acid in a meat grinder, and the results showed that biomass moisture above 17% yielded less than 50% glucose. Sulfuric acid exhibited the best performance with a glucose yield of 74.5%, and the glucose yield had a direct relationship with the non-carbohydrate components of biomass.
