In a lab, maybe.
But as a practical application, (i.e. plastic into jet fuel, not requiring much more energy input as you get in return) I call BS.
Normally I’d agree with you, but might have some big pluses:
1. Conversion efficiency — 90%
2. Speed — one hour
3. Low temperature — 430 F
Of course, problems remain:
1. What is the magic catalyst?
2. Do the plastics need to be separated by type?
3. Collection of used plastics is a highly distributed nightmare process.
Maybe worthwhile, when if/when the earth runs out of oil. Until then, seems we’d create a lot of mess mining for ruthenium.
