Process for using biogenic carbon dioxide derived from non-fossil organic material
First Claim
1. A process for producing a fuel or fuel intermediate containing carbon derived from non-fossil organic material comprising:
- (i) providing biogenic carbon dioxide that is sourced from a production process comprising at least one of a step of fermentation and a thermal process, said production process producing a first product derived from the non-fossil organic material, said first product selected from;
(a) an energy product;
(b) a biogenic carbon-based product selected from a chemical product, a fuel and a fuel intermediate; and
(c) a combination thereof, wherein the biogenic carbon dioxide is generated during the production process;
(ii) providing a stream enriched in hydrogen that is sourced from a hydrogen production process, the hydrogen production process including a step of removing fossil carbon dioxide from a stream including hydrogen to provide the steam enriched in hydrogen;
(iii) converting the biogenic carbon dioxide and hydrogen from the enriched hydrogen stream to a second product, said second product comprising at least one of a biogenic carbon-based fuel and a biogenic carbon-based fuel intermediate; and
(iv) carrying out or arranging for one or more parties to carry out at least one step that contributes to a reduction in the life cycle greenhouse gas (GHG) emissions of the second product.

Abstract
The present disclosure provides a process for forming a biogenic carbon-based fuel or a fuel intermediate from biogenic carbon dioxide and hydrogen. The hydrogen is sourced from a process that produces hydrogen and fossil carbon dioxide from a fossil-fuel hydrocarbon and separates the fossil carbon dioxide from the hydrogen. The process may further comprise carrying out or arranging for one or more parties to carry out at least one step that contributes to a reduction in the GHG emissions of the biogenic carbon-based fuel, or a fuel made from the fuel intermediate, of at least 20% relative to a gasoline baseline. In various embodiments this includes (a) introducing the fossil carbon dioxide underground, and/or (b) using a biogenic carbon-based product selected from a chemical and energy product produced from the non-fossil organic material to displace the use or production of a corresponding fossil-based product.
