Comprehensive Utilisation of Biomass Tar for High Volumetric Capacitance Porous Carbon and Modifi ed Bio-resin
Abstract
Biomass tar is a by-product generated during biomass gasifi cation. Because of the toxic and harmful nature of biomass
tar, its treatment method has become the concern of environmental protection fi eld and related researchers. In this paper,
biomass tar was separated into the heavy tar and the phenol-containing liquor after enrichment. Porous carbon (PCs) was
prepared using the heavy tar by one-step carbonization activation. The results show that PC_3 has the highest specifi c surface
area of 352 m 2 g −1 and mesoporosity ratio of 56.25%. The as-prepared electrode displayed an excellent electrochemical
performance for portable super-capacitors, which is a volumetric capacitance of 349 F cm −3 . Assembled super-capacitors
have an energy density of 21.65 Wh kg −1 at a power density of 123 W kg −1 . The bio-resins were modifi ed with the phenolcontaining
liquor. The results showed that the thermal stability of modifi ed resins had been improved and the structure did
not change signifi cantly. This research provides an environmentally friendly and comprehensive utilisation methods for the
utilisation of biomass tar.
