Thermochemical production of biokerosene and biodiesel

Overview

ABSTRACT

The thermochemical pathway is used to obtain second-generation biofuels from lignocellulosic biomass. The indirect thermochemical route starts with a first stage of pretreatment of the biomass, which is then transformed into synthesis gas by partial oxidation in a gasification unit. This synthesis gas, a mixture of carbon monoxide (CO) and hydrogen (H2) is then conditioned and cleaned up to meet the specifications for the Fischer-Tropsch synthesis, which produces liquid hydrocarbons. The last step in this process chain is the upgrading of the hydrocarbon effluents to adjust the properties. The main end products are high quality kerosene and diesel fuel; these products do not contain sulfur or aromatics, and can readily supplement or replace fossil fuels.
