=== HTL Process Mechanism ===

Hydrothermal liquefaction is a [[biomass]] to bio-liquid conversion route carried out in water at moderate temperature and high pressures that has a liquid bio crude as main product along with the gaseous, aqueous and solid phase by-products. Many complex reactions take place during the transformation of [[biomass]] into crude oil like products due to the complex structures of the [[feedstocks]] which are to be broken down. The pathway of HTL comprises three major steps: depolymerisation, decomposition and recombination. Overall, [[biomass]] is decomposed and depolymerized into small compounds which may be highly reactive, thus polymerizing and forming bio crude, gas and solid compounds is essential. Also, critical process parameters such as temperature, residence time, the process of repolymerization, condensation and decomposition of the components from the different phases may vary.
