Methane >> carbon dioxide as a polyethylene/linear polymers feed stock. Double bonded oxygens are hella higher affinity than four loose hydrogens. Also as pointed out, even in a concentrated combustion effluent stack CO2 is low concentration at atmospheric pressure.
I don’t know about methane as an aromatic/hybridized ring building block. Anything is possible with chemical synthesis but is it energy feasible.
There’s always plant hydrocarbon feed stocks but I think using arable land to make plastics is dumb and also carbon intensive. (I do wear cotton clothing tho because you need to make trade offs).
- whatever1 5mo agoSiemens has a collaboration with Porsche are piloting already eFuel production. Cost is super high (think like $10/liter). But thermodynamically feasible. https://www.siemens-energy.com/global/en/home/press-releases/lighthouse-project-southern-tip-chile-production-starts-worlds-first-industrial-scale.html#:~:text=A%20lighthouse%20project%20at%20the,facility%20for%20carbon%2Dneutral%20fuel https://www.siemens-energy.com/global/en/home/press-releases...
