Biomass is a renewable and abundant resource that can be used to produce important compounds like levulinic acid and levulinate esters, with the help of efficient solid acid catalysts. The challenges and prospects in the production of these compounds from biomass are discussed in order to achieve a more economical and energy efficient process in line with sustainable development goals.
Biomass is a kind of renewable and abundant resource that can be seen as an important candidate to solve the energy crisis. Levulinic acid (LA) and levulinate esters (LEs) have been widely researched as biomass-based platform compounds. In recent years, efficient, green, and environment-friendly solid acid catalysts have been developed for the fast production and resolution of the problems, such as low yield, high equipmental requirements, and difficulty in product separation, in the preparation of LA and LE from biomass. In this paper, the preparation routes of LA and LEs from various raw materials are introduced, and the solid acid catalysts involved in their production are emphatically reviewed. The challenges and prospects in LA and LE production from biomass are proposed to achieve a more economical and energy efficient process with the concept of sustainable development in the future.
