Abstract
Provided herein are systems and methods for converting CO2 and a reduction gas such as H2 or a hydrocarbon to mixtures of paraffins and aromatics suitable for use as aviation fuel.
Claims20
A system for the production of aviation fuel comprising:
- a first reduction gas feed;
- a first carbon source feed;
- a paraffin reactor comprising a reduction catalyst, said paraffin reactor having a first reduction gas feed inlet, a first carbon source inlet, and a paraffin product outlet, wherein the first reduction gas feed is coupled to the first reduction gas feed inlet, and the first carbon source feed is coupled to the first carbon source feed inlet;
- a second reduction gas feed;
- a second carbon source feed;
- an aromatic reactor comprising an aromatic catalyst, said aromatic reactor having a second reduction gas feed inlet, a second carbon source inlet, and an aromatic product outlet, wherein the second reduction gas feed is coupled to the second reduction gas feed inlet, and the second carbon source feed is coupled to the second carbon source feed inlet;
- and
- a blender having a paraffin product inlet, an aromatic product inlet, and a blended product outlet, wherein the paraffin product outlet from the paraffin reactor is coupled to the paraffin product inlet of the blender, and the aromatic product outlet from the paraffin reactor is coupled to the aromatic product inlet of the blender.
5 more elements
A method for the production of aviation fuel comprising:
- contacting a first reduction gas and a first carbon source gas with a reduction catalyst to afford a paraffin product mixture comprising one or more paraffins;
- contacting a second reduction gas and a second carbon source gas with an aromatic catalyst to afford an aromatic product mixture comprising one or more aromatics and/or cyclic paraffins;
- blending the paraffin product mixture and the aromatic product mixture to afford a crude product mixture.
