Preparation of carbon materials by thermochemical conversion of lignin

Date: 04 December 2014

Country: Spain

Application

• The usage interest of lignin-based carbon fibers includes both high-performance applications (structural applications, aerospace, military, sporting and luxury goods) and general-purpose applications (adsorption, catalysis, energy storage and conversion).

Description

This study explores the development of a novel, sustainable, and cost-effective method for producing carbon fibers from lignin, a renewable resource . The researchers investigated the use of lignin as a precursor for carbon fiber production, which could potentially replace traditional petroleum-based materials. The project aimed to optimize the processing conditions and characterization of the resulting carbon fibers, paving the way for the development of sustainable and renewable carbon fiber materials.

Pathway Description:

The conventional manufacture of CFs from a given isolated industrial lignin mainly involves five successive processing steps: (i) purification and/or modification, (ii) spinning into lignin fibers, (iii) oxidative thermostabilization, (iv) carbonization, and (v) post-treatment.
