Abstract
In at least one embodiment of the present invention, a method for producing liquid hydrocarbons from biomass is provided. The method comprises pyrolizing the biomass with hydrogen (H2) to form bio-oil. The bio-oil comprises alkanes, alkenes, alcohols, aldehydes, ketones, aromatics, hydrocarbons or mixtures thereof. The H2 is formed from a carbon-free energy source.
Claims25
A method for producing liquid hydrocarbons from biomass that contains carbon, the method comprising:
- forming hydrogen (H2) from a carbon-free energy source;
- and
- hydropyrolizing the biomass to form bio-oil that comprises alkanes, alkenes, alcohols, aldehydes, ketones, aromatics, hydrocarbons or mixtures thereof, wherein hydropyrolizing comprises fast pyrolysis in a presence of H2.
A method for producing liquid hydrocarbons from biomass that contains carbon, the method comprising:
- pyrolizing the biomass free from H2 to form a reactor effluent stream;
- separating char from the reactor effluent stream;
- reacting the reactor effluent stream and H2 to form upgraded bio-oil;
- and
- recovering the upgraded bio-oil.
A system for producing liquid hydrocarbons from biomass that contains carbon, the system comprising:
- a first unit configured to form hydrogen (H2) from a carbon-free energy source;
- and
- a second unit configured to hydropyrolize the biomass in presence of H2 to form bio-oil that comprises alkanes, alkenes, alcohols, aldehydes, ketones, aromatics, hydrocarbons or mixtures thereof, the H2 being formed from using a carbon-free energy source.
