Abstract
In brief, the invention is a process for the conversion of molecules containing one or more alcohol functionalities to larger molecules. Alcohols such as methanol, ethanol, propanol and hexanol and diols/glycols, such a propylene glycol and butanediol are fed to supported metal catalyst such as a noble metal/solid acid catalyst in the presence of hydrogen at elevated temperatures and pressures create a mixture of hydrocarbon and oxygenate products.
Claims18
A process for converting C1 to C4 bio-sourced molecules with one or more oxygen containing functionalities to C5+ hydrocarbons comprising:
- a) providing a C1 to C4 alcohol stream from a biomass conversion process;
- b) contacting the C1 to C4 alcohol stream with supported metal catalyst at a temperature of at least 500° F. and a pressure of at least 1000 psi, where the C1 to C4 alcohol stream is converted to a higher value stream containing hydrocarbons and oxygenates with carbon numbers of between six and 30;
- and
- c) deoxygenating the higher value stream to remove oxygen from the oxygenate molecules and produce hydrocarbons that may be separated into feedstocks for at least one of gasoline, diesel, jet and gas oil.
