Method and system for carbon capture and recycling
A method for carbon capture and recycling, the method including the steps of: (i) Capturing CO 2 from at least one CO 2 containing input; (ii) Producing a CO 2 feed stream from the captured CO 2 ; and (iii) Reacting the CO 2 feed stream with a H 2 feed stream to produce a methane containing output.
1. A method for recycling CO 2 from CO 2 containing inputs to produce hydrocarbon products, the method including the steps of:
(i) capturing CO 2 from at least one CO 2 containing input, wherein one of the at least one CO 2 containing input includes air;
(ii) producing a CO 2 feed stream from the captured CO 2 ;
(iii) reacting the CO 2 feed stream with a H 2 feed stream to produce a methane containing output;
(iv) separating the methane containing output so as to at least provide methane and a first waste output, wherein the first waste output is incinerated or gasified to provide one of the at least one CO 2 containing inputs for step (i);
(v) processing methane from the methane containing output to produce an acetylene containing output; and
(vi) separating the acetylene containing output so as to at least provide acetylene and a second waste output.
2. A method as claimed in claim 1 , wherein one of the at least one CO 2 containing inputs is derived from incinerator exhaust streams or industrial plumes.
3. A method as claimed in claim 1 , wherein the H 2 feed stream is provided by a water electrolysis process.
4. A method as claim in claim 3 , wherein water produced during step (iii) is provided for the water electrolysis process.
5. A method as claimed in claim 1 wherein, in step (i), CO 2 is captured using a Calcium Oxide sorbent.
6. A method as claimed in claim 1 , wherein the second waste output is incinerated or gasified to provide one of the at least one CO 2 containing inputs for step (i).
7. A method as claimed in claim 6 , wherein step (v) includes heating the methane with a thermal plasma reactor.
8. A method as claimed in claim 1 , further including the step of
(v) heating methane from the methane containing output with a thermal plasma reactor to produce a hydrocarbon containing output, wherein the thermal plasma reactor is configured such that plasma is provided in feed with the methane.
9. A method a claimed in claim 8 , further including the step of
(vi) separating the hydrocarbon containing output so as to at least provide one or more preselected hydrocarbon products and a second waste output.
10. A method as claimed in claim 9 , wherein the second waste output is incinerated or gasified to provide one of the at least one CO 2 containing inputs for step (i).
