Biochar is a recalcitrant carbonaceous material obtained from pyrolysis and gasification of biomass and other biogenic wastes. Some of the promising biochar applications to be discussed in this presentation includes char gasification and combustion for energy production, soil remediation, carbon sequestration, catalysis, and development of activated carbon and specialty materials with biomedical and industrial uses. Several factors such as pyrolysis/gasification temperature, heating rates and residence time are the limiting factors that determine the biochar properties such as fixed carbon, volatile matter, mineral matter, surface area, porosity and pore size distribution, alkalinity, electrical conductivity, cation-exchange capacity, etc. This paper will comprehensively review the evolution of biochar from several lignocellulosic biomasses influenced by gasification temperature and residence time.
