Benefits of technology
[0007]The present invention provides methods for producing hydrocarbon products such as gasoline and lower olefins from renewable sources. The methods of the present invention may have reduced adverse environment effects and / or economic cost compared to existing technologies relying on the extraction and use of crude oil. Additionally or alternatively, hydrocarbon products produced by the methods of the present invention may be of comparable or increased quality to those produced from crude oil and other similar feedstocks.
Problems solved by technology
Gasoline is currently produced from crude oil in oil refineries, however, as world crude oil reserves are being rapidly depleted there are concerns regarding potential global shortages of gasoline in the future.
Reduced crude oil supply is likely to lead to further increases in the price of gasoline.
Furthermore, sulfur and nitrogen-containing compounds in crude oil have adverse affects on the environment during the production of gasoline and other hydrocarbon compounds such as lower olefins.

Cracking of Lignite and Bio-Oil Syncrudes
[0172]FIG. 9 shows a schematic of a Micro Activity Test (MAT) unit comprising a fixed bed of catalyst contained in a Pyrex glass reactor supported in a temperature controlled furnace. The lignite and bio-oil syncrudes were Used as feeds to the MAT unit as follows:
Condensate (lignite oil)Syncrude (Bio-oil)100090107030
[0173]The MAT unit that was operated at the conditions shown below:[0174]Contact Time (TOS): 30 seconds[0175]Catalyst to Oil Ratio (CTO): 2-6 (WHSV=20-60 h−1)[0176]Temperature=500° C.[0177]Catalytic Cracking Equilibrium Catalyst:[0178]surface area 290 m2 / g; ˜30% zeolite Y with a unit cell dimension (UCS) of 24.28 Å
[0179]The catalyst was charged to the reactor and preheated under nitrogen flow. The catalyst was an equilibrium sample with the properties given above.
[0180]The syncrude feeds were injected at a controlled rate using a syringe pump. Following the feed injection cycle, remaining hydrocarbons are stripped from the catalys...

Abstract
The present invention relates to a method for producing a hydrocarbon product from coal and/or biomass comprising the following steps: converting the coal to a coal-oil and/or converting the biomass to bio-oil, optionally processing the coal-oil and/or bio-oil in a hydroprocessing reaction to remove one or more of oxygen, nitrogen or sulfur from hydrocarbon compounds in the coal-oil and/or bio-oil; and using at least a portion of the coal-oil and/or bio-oil as a feedstock in a cracking reaction to convert hydrocarbon compounds in the feedstock into a mixture of smaller hydrocarbon compounds comprising the hydrocarbon product.
Description
INCORPORATION BY CROSS-REFERENCE[0001]This application claims priority from NZ provisional application no. 580653 filed on 27 Oct. 2009 and NZ provisional application no. 580654 filed on 27 Oct. 2009, each of which is incorporated herein by cross-reference in its entirety.FIELD OF THE INVENTION[0002]The present invention relates generally to the production of hydrocarbon fuels and in particular the production of renewable hydrocarbon fuels. More specifically, the present invention provides processes for converting bio-oils produced from biomass and / or coal-oils produced from coals into hydrocarbon products such as gasoline and lower olefins.BACKGROUND[0003]Current processes for producing hydrocarbon products such as gasoline and lower olefins are generally conducted in conventional oil refineries and petrochemical complexes and rely on the distillation of crude oil.[0004]Gasoline comprises aliphatic hydrocarbons with seven to eleven carbon atoms and is a petroleum product that is vi...
