Efficient hydrothermal hydrodeoxygenation of triglycerides with in situ generated hydrogen for production of diesel-like hydrocarbons

An integrated catalytic transfer hydrogenation (CTH) and aqueous phase reforming (APR) process was applied for the hydrothermal hydrodeoxygenation of triglycerides to diesel-like hydrocarbons in the presence of water. Up to 71.91% yield of diesel-like hydrocarbons (C17+C18 products) could be achieved when using decalin as solvent at 523K with autogenous pressure after 12h of reaction time. The promotional effect on the hydrodeoxygenation of triglycerides was ascribed to the high reactivity of in situ generated H2 from solvents.
