Abstract

Liquid fuels from biomass will form an essential part of meeting the grand challenges within energy. The need for renewable and sustainable energy sources is triggered by a number of factors; like increase in global energy
demand, depletion of conventional resources, climate issues and the desire for
national/regional energy independence. Especially in marine, aviation and heavy
land transport suitable carbon neutral drop-in fuels from biomass are needed,
since electrification of those is rather unlikely. Hydrothermal conversion (HTC)
of biomass offers a solution and is a sustainable way of converting biomass
feedstocks to valuable bio-crude. HTC is a high pressure and medium temperature thermochemical biomass conversion process and converts aqueous biomasses under sub- or super-critical conditions to a bio-crude similar to fossil crude oil.
This chapter deals with the chemical reaction pathways during hydrothermal
conversion of lignocellulosic biomass and upgrading pathways of bio-crude components with focus on hydrodeoxygenation reactions.
