Solvent refined coal

Solvent refined coal

...Hydrogen is donated from the solvent to the free radicals produced by this decomposition reaction, and if they are stabilized, the liquefaction reaction is realized. The SRC (solvent refined coal) process was originally intended to remove ash from coal and obtain solvent refined coal (solid), but by making the reaction conditions somewhat stricter, it has been improved to produce liquefied oil equivalent to crude oil. The EDS (Exxon donor solvent) process and the solvolysis process are both similar in principle to the SRC process, but the solvolysis process uses petroleum-based asphalt as a solvent and is a technology conceived in Japan. ...

Japanese:

…この分解反応によって生じた遊離基(ラジカル)に溶剤から水素が供与され,安定化すれば液化反応が実現される。SRC(solvent refined coal)法は元来は石炭中の灰分の除去を主目的とし,溶剤精製炭(固型)を得る方法であったが,反応条件をやや厳しくすることにより,原油に相当する液化油を生産する方向に改良された。EDS(Exxon donor solvent)法とソルボリシス法はいずれも原理的にはSRC法と類似であるが,ソルボリシス法は石油系アスファルトを溶剤として用いるもので,日本で着想された技術である。…
