What is the Application of Levulinic Acid in Fuel Additives?
Levulinic acid, also known as 4-oxopentanoic acid, is an organic compound classified as a keto acid. It is a soluble white crystalline solid in both water and polar organic solvents. Levulinic acid is derived from the degradation of cellulose and has the potential to be used as a precursor to biofuels, specifically ethyl levulinate.
The production of levulinic acid can be achieved through high-temperature acid carbohydrates hydrolysis, including galactose, glucose, sucrose, chitose, fructose, as well as materials such as wood, agricultural wastes, and starch.
Biofine vs. Acid Hydrolysis Process
When comparing the Biofine process to acid hydrolysis, the latter is widely used for producing levulinic acid and its derivatives. Acid hydrolysis allows for a broader range of lignocellulosic feedstock utilization and has gained popularity due to increasing awareness of its benefits. Commercial production concepts often rely on acid hydrolysis technology, which involves continuous processes at high pressures and temperatures.
Additionally, the inclination towards deriving levulinic acid from biomass and rice husk has further driven the requirement for acid hydrolysis technology. Extensive research on cellulose acid hydrolysis for levulinic acid production has also contributed to the adoption of this approach.
The Biofine process, on the other hand, is chosen for levulinic acid production because it does not involve the use of microorganisms for fermentation, unlike the hydrolysis process. This characteristic has made the Biofine process popular, and its adoption is expected to increase rapidly in the coming years, thanks to the growing awareness of its benefits.
With the growing environmental concerns and the shift towards organic and bio-based fuel additives, the demand for levulinic acid is expected to increase in the future.
Asia currently represents the largest and fastest-growing sector for levulinic acid. This is because of the high requirement for levulinic acid in the production of fuel additives such as n-butyl levulinate, the widespread adoption of biobased products in various applications, including drugs, personal care products, and agricultural products, in countries like China, India, Thailand, and Indonesia, and the rise in disposable income in the region.
Furthermore, as bio-based production methods become more commercialized and there is increased research and development in the personal care sector, the global requirement for levulinic acid will continue to rise, reaching a value of USD 61.04 million by the end of this decade.
