AI Technical Summary

Benefits of technology

[0015]In certain embodiments, the invention relates to a method of increasing the flash point of a starting liquid by devolatilization of the starting liquid, wherein the starting liquid is produced from thermal conversion, the method comprising: supplying the starting liquid to a first component; h...

Problems solved by technology

This is in stark contrast to slow pyrolysis, which produces a thick, low quality, two-phase tar-aqueous mixture in very low yields.

If the flash point is too low it causes the fuel to be subject to flashing and po...
