Integrated system and method for producing fuel composition from biomass

An integrated method for processing a bio-oil feedstock, comprising:

• (a) subjecting said bio-oil feedstock to an oil extraction process to produce a bio-oil and a substantially deoiled residue;
• (b) gasifying at least a portion of said substantially deoiled residue to generate a hydrogen-containing gas;
• (c) using said hydrogen-containing gas in upgrading said bio-oil by hydro-treating, hydro-isomerization, and separation steps, to produce a fuel composition and light hydrocarbons;
• and
• (d) directing at least a portion of said light hydrocarbons to gasification step (b), so as to reduce tar levels associated with gasification.

A method for producing jet fuel from a bio-oil feedstock, comprising the steps of:

• extracting a bio-oil from said bio-oil feedstock, producing a substantially deoiled residue as a byproduct;
• upgrading said bio-oil to produce said jet fuel;
• gasifying at least a portion of said substantially deoiled residue to generate a hydrogen-containing gas;
• and
• supplying at least a portion of said hydrogen-containing gas in said upgrading of said bio-oil to produce said jet fuel.
