Production and Applications of Pyrolytic Oil and Char from Lignocellulosic Residual Biomass

Abstract

The emission of greenhouse gases (GHG) is a major concern for the scientific community due to its contribution to climate change. The valorization of organic wastes, such as lignocellulosic biomasses, by thermochemical processes to obtain value-added compounds is a highly promising option to mitigate GHG emissions and decrease the consumption of natural resources. Thermochemical valorization provides three main byproducts: syngas, pyrolytic oil, and biochar. According to operating conditions, it is possible to orient the thermochemical reactions to focus on one main byproduct. This chapter discusses the production and applications of oil and biochar, which have high potential for use in various industrial sectors. For example, pyrolytic oil can be used as a fuel to generate heat and power or as a raw material for biorefineries. Biochar can be also used as solid fuel or as a carbon sink when applied as soil amendment, and it is a promising catalytic support or adsorbent. The chapter also discusses the main challenges to the development of an industrial production of these two byproducts and their emerging applications.
