Lignin can donate to methyl ester production or not? is there any chances that lignin and rice husk can be helpful for ester production by transesterification.
Dear Deepayan,
In biodiesel production process, the development and research of novel and efficient ways using solid catalysts for the transesterification of inedible oil into biodiesel are the key industrial challenges. Solid acid catalysts have gained considerable attention due to their advantages of noncorrosion, non-toxicity, water tolerance, and easy separation for recycling. Novel solid acid catalysts derived from sulfonation of carbonized lignin was reported and studied extensively. Although lignin is a non-carbohydrate biopolymer with cross-linked aromatic structure, it can be carbonized in a similar way. Therefore, lignin can be heterogeneous acid catalyst for methyl ester production.
About rice husk, after carbonized process (pyrolysis process), it can also be an appropriate catalyst for biodiesel production process as well.
Good luck,
Dang
depending on scope. As lignin was separated as oil soluble stock in biomass it can be blended to biodiesel if the scope of use is heating oil. Special care to additivation will be required. If the scope of use is automotive fuel the same cannot be done that simple.I do not see much of using lignin as solid catalyst, but through steps of diccifult synthesis and conversion yes. Q: is it worth?
