I detect a difference of opinion. It puts me in mind of dense thermal depolymerization, which I guess is now https://en.wikipedia.org/wiki/Hydrothermal_liquefaction.
Quote:
Hydrothermal liquefaction (HTL) is a thermal depolymerization process used to convert wet biomass into crude-like oil -sometimes referred to as bio-oil or biocrude- under moderate temperature and high pressure.[1] The crude-like oil (or bio-oil) has high energy density with a lower heating value of 33.8-36.9 MJ/kg and 5-20 wt% oxygen and renewable chemicals.[2][3]
The reaction usually involves homogeneous and/or heterogeneous catalysts to improve the quality of products and yields.[1] Carbon and hydrogen of an organic material, such as biomass, peat or low-ranked coals (lignite) are thermo-chemically converted into hydrophobic compounds with low viscosity and high solubility. Depending on the processing conditions, the fuel can be used as produced for heavy engines, including marine and rail or upgraded to transportation fuels,[4] such as diesel, gasoline or jet-fuels.
