EXXON donor solvent

Japanese: EXXON donor solvent(英語表記)EXXONdonorsolvent
EXXON donor solvent

…The SRC (solvent refined coal) process was originally intended to remove ash from coal and produce solvent refined coal (solid), but by making the reaction conditions somewhat stricter, it was 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.
[Indirect coal liquefaction]
In this method, coal is first gasified and converted into synthetic gas consisting of carbon monoxide and hydrogen, and then a reaction is carried out over a catalyst to synthesize hydrocarbon oil.

Japanese:

…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。
[石炭の間接液化]
 石炭をひとまずガス化して一酸化炭素と水素からなる合成ガスに変換したのち,触媒上で反応を行わせて,炭化水素油を合成する方法である。…
