Lignin extraction and green-like lignocellulose biomass pyrolysis as an alternative sustainable biofuel

Abstract

Cellulose, hemicellulose, and lignin make up the majority of biomass energy, which is a sustainable and renewable feedstock. Since lignin is the most common naturally occurring aromatic polymer on Earth, it holds great promise for useful products. Separating lignin from cellulose in biomass before converting it to biofuels or bioproducts is a crucial pre-treatment step. Alkali acid can be used to extract lignin from non-food components that remain following agricultural processing. As a result, we achieve the required lignin by the above procedure was used. The results demonstrate an extraction process of 5 hours, 4 hours, and 3 hours at 100 degrees Celsius, 130 degrees Celsius. Utilizing NaOH and H2SO4 for liquor and biomass to liquor ratio of 1:20. The total lignin content of the walnut shell was 13% lignin yield at 5 hr as well as neem tree bark biomass was found to be 5 % at 3 hours and walnut shell 14 % at 5 hr as well as 8% at 3 hours for almond shell lignin yield. It can be seen that the walnut shell produced the most lignin when compared to other types of biomass.
