Study of Chemical Pulping Process and Extraction of Lignin, Cellulose

If you are looking for final year Chemical engineering project, then this project on "study of the chemical pulping process and extraction of lignin, cellulose" can be your next big idea for the project. This project is for specific branches of Chemical engineering i.e. POLYMER. Lignin is a natural resource which exists in woody materials, agricultural residues, and other plant materials (so-called lignocellulosic materials). You can also Subscribe to FINAL YEAR PROJECT'S by Email for more such projects and seminar.


Lignocellulosic materials consist of 10–30% lignin by weight and 40% by energy. However, it has mainly been used as an energy source in combustion processes, and less than 5% lignin has been used for other purposes nowadays.

Lignin has high energy content and polymer structure, that is why it is considered as a potential renewable resource of chemicals and fuels mainly in condition of escalating petroleum rate and renewable energy demand. Lignin de-polymerization is very promising method that could generate cost added merchandise from lignin raw materials. The main purpose of lignin depolymerization is to convert the complex lignin compound into small molecules for fuels and basic chemicals or oligomers for further application.

Lignin is a complex polymer of aromatic alcohols known as monolignols. It is most commonly derived from wood, and is an integral part of the secondary cell walls of plants and some algae.

Structure of Lignin

Lignin represents the second most ample natural polymeric fabric on planet and is still currently underutilized. Massive quantities of lignin are anticipated to be produced in future bio-refineries as a by-product of bio-fuel production which is stimulating new emerging applications, principally as sustainable options to nonrenewable products which include polyurethanes, thermoplastic polymers, epoxy and phenolic resins, as well as corrosion inhibitors.

However, all the researches currently developed in these fields are carried out at the laboratory scale. Thus, the ability of organosolvlignin’s to provoke significant impact as a substitute for polymeric materials depends on its availability in industrial quantities.

From this project, the result achieved meet the expected values from a calculation that be expected. The values that have been declared fulfill the desired value. This project works teach about the cellulose, ligning and fiber and their applications and productions. Thanks to the author of the project.
