Forest-based industries generate significant amount of residues, some of which are processed by fast pyrolysis and transformed into bio-oil. This is the case of waste generated in pre-consumption (harvests), such as bark, branches and leaves, whose bio-oil is currently used as fuel for boilers in cold climate countries for heating purposes. On the other hand, bio-oils made from lignocellulosic material has enormous potential to be transformed into Sustainable Aviation Fuel (SAF), which can be done by feeding bio-oil and hydrogen in a reactor in the presence of a solid catalyst, a process called hydrodeoxygenation (HDO).
Among other purposes, the HDO process is used to remove unsaturation and oxygenation of organic species, leading to increased heating value and decreased viscosity and humidity. This kind of SAF is called Synthetic Paraffinic Kerosene obtained from Hydroprocessed Esters and Fatty Acids (SPK-HEFA). The use of SPK-HEFA in jet aviation was recently regulated by the Brazilian National Agency for Petroleum, Natural Gas and Biofuels (ANP, Resolution Nr 856, 10/22/2021), stipulating composition and physicochemical properties of the synthetic fuel, as well as the mixture proportion (up to 50% v/v) with traditional fossil kerosenes (JET A and JET A-1). The success of this research can contribute to adding value to bio-oil from lignocellulosic material, generating jobs due to the opening of a new process line, in addition to partially replacing fossil by renewable fuels.
