Abstract
The present invention relates to a process and system for forming a hydrocarbon feedstock from a biomass material, and the hydrocarbon feedstock formed therefrom. The present invention also relates to a process and system for forming a bio-derived naphtha fuel from a hydrocarbon feedstock, and the bio-derived naphtha fuel formed therefrom, as well as intermediate treated hydrocarbon feedstocks formed during the process.
Claims23
A process for forming a biomass derived hydrocarbon feedstock, suitable for producing bio-naphtha, from a biomass feedstock, comprising the steps of:
- a. providing a biomass feedstock;
- b. ensuring the moisture content of the biomass feedstock to 10% or less by weight of the biomass feedstock;
- c. pyrolyzing the low moisture biomass feedstock at a temperature of at least 950° C. to form a mixture of biochar, hydrocarbon feedstock, non-condensable light gases, and water;
- and
- d. separating the hydrocarbon feedstock from the mixture formed in step c.
A process of forming a bio-derived naphtha fuel, comprising the steps of:
- A. providing a biomass derived hydrocarbon feedstock formed by:
- i. providing a biomass feedstock;
- ii. ensuring the moisture content of the biomass feedstock to 10% or less by weight of the biomass feedstock;
- iii. pyrolyzing the low moisture biomass feedstock at a temperature of at least 950° C. to form a mixture of biochar, hydrocarbon feedstock, non-condensable light gases, and water;
- and
- iv. separating the hydrocarbon feedstock from the mixture formed in step Aiii;
- B. processing the hydrocarbon feedstock to produce a refined bio-oil, wherein the process comprises the steps of:
- i. at least partially removing sulphur containing components from the hydrocarbon feedstock;
- ii. hydro-treating the hydrocarbon feedstock;
- and
- iii. hydro-isomerising the hydrocarbon feedstock;
- and
- C. fractionating the resulting refined bio-oil to obtain a bio-derived naphtha fuel fraction.
