Abstract

The use of lignocellulosic biomass as a future substitute for fossil fuels depends on the successful development of biorefinery strategies for the production of renewable derived-building blocks. In this context, levulinic acid has been pointed out as a polysaccharide-derived organic acid with a great potential for several applications such fine chemicals, fuels, fuel additives, pharmaceuticals, and pesticides. Bearing this in mind, the goal of this project will be investigating the production of levulinic acid by subcritical water and CO2 hydrolysis (SbWH and SbCO2H) of sugarcane bagasse. This technique has been considered as an environmentally friendly catalytic process with potential applications in synthesis reactions. In addition, CO2 is also attractive as a chemical for organic chemistry because it is nontoxic, nonflammable, inexpensive, and renewable, being in agreement with the principles of green chemistry.
