Thermochemical conversion of agricultural waste to biojet fuel

Abstract:

This chapter comprehensively assessed the approved American Society for Testing and Materials (ASTM) routes’ potential for biojet fuel production from agricultural waste as feedstock. Due to its renewability and availability, lignocellulosic biomass is the most promising feedstock. Approved technologies involve the upgrading of lignocellulose-derived alcohol into jet fuel (ATJ); triglycerides and vegetable oil catalytic hydrothermolysis jet (CHJ); hydroprocessed esters and fatty acids (HEFA); power-to-liquid conversion of syngas through a Ficher-Tropsch (FT) reactor; synthesized kerosene with increased aromatics content (FT-SPK/A); and hydroprocessed synthesized isoparaffins via hydroprocessed fermented sugars (SIP-HFS). Depending on the processing pathway and feedstock sort employed, the produced biojet fuel contains linear, branched, and cyclic hydrocarbons, ensuring the physicochemical homogeneity and high-quality combustion required for a “drop-in” Jet A1 blending component.
