RE:Not a expert https://www.catalytec.com/index.php/catalytic-fuel-technology
this is the tech that Cielo originally in-licensed but because there was a tar-like byproduct Cielo decided to design some additional processes in so there was no tar-like byproduct. This is how Cielo was able to get a patent approved. But so far, the damn thing does not work!
- Any inert or other materials not processed, including spent catalyst and salts, are discharged as tar-like slurry, which typically accounts for 5% of total throughput. It can be use as a paving or roofing product extender, or baked dry and used as road base or filler.
