H-Coal Method - H-Coal Method

...The technologies are broadly divided into direct liquefaction and indirect liquefaction.
[Direct coal liquefaction]
This is a method of directly converting solid coal into liquid fuel, and is classified into three types according to the principle: (1) low-temperature carbonization (COED method), (2) catalytic hydrocracking (Bergius method, H-Coal method), and (3) non-contact solvent extraction (SRC method, EDS method, solvolysis method). (1) Low-temperature carbonization This is a method in which coal is carbonized at a relatively low temperature (400-600°C) and the resulting low-temperature tar is refined to produce liquid fuel. Examples include the COED (coal oil energy development) method, but the disadvantage is that the yield of liquid products is low.

…この技術は直接液化と間接液化に大別される。
[石炭の直接液化]
 固体である石炭を直接的に液体燃料に変換する方法で,原理によって,(1)低温乾留法(COED法),(2)接触水素化分解法(ベルギウス法,H‐Coal法),(3)非接触溶剤抽出法(SRC法,EDS法,ソルボリシス法)の3種類に分類される。(1)低温乾留法 石炭を比較的低温(400~600℃)で乾留し,得られる低温タールを精製して液体燃料とする方法で,COED(coal oil energy development)法などがあるが,液体製品の収率が低いのが欠点である。…
