Coal liquefaction is a process that converts COAL from a solid state into liquid fuels, usually to provide substitutes for petroleum products. Coal liquefaction processes were first developed in the early part of the 20th century but later application was hindered by the relatively low price and wide availability of crude oil and natural gas. Large scale applications have existed in only a few countries, eg, Germany during WWII and South Africa since the 1960s. The oil crises of the 1970s and the threat of depletion of conventional oil supplies sparked a renewed interest in the production of oil substitutes from coal during the 1980s. However, as was the case for COAL GASIFICATION, the wide availability of inexpensive oil and natural gas supplies in the 1990s has effectively killed the near-term commercial prospects of these technologies.

煤炭液化是将固态煤炭转化为液态燃料的工艺,它通常用作石油制品的替代品。煤炭液化工艺最早发展于20世纪初期,然而其应用却因原油及天然气的低廉价格与广泛使用而停滞不前。该工艺的大规模应用只是出现在极少数国家,比如二战中的德国以及20世纪60年代后的南非。20世纪70年代的石油危机以及传统石油供应枯竭的威胁重又在80年代让人们对从煤炭中寻找石油替代品产生了兴趣。然而就煤炭气化而言,90年代廉价石油及天然气的广泛使用已经有效扼杀了人们近期对这些技术的商业期望。

煤炭液化是改变信仰者煤炭从固态入液体燃料, 通常提供石油产品的替补的过程。煤炭液化过程第一次被开发了在20 世纪的早期部分但最新应用由原油和天然气的相对地低价和宽可及性妨害了。大规模应用存在了在唯一几个国家, 即, 德国在二战期间和南非从60 年代。70 年代和常规石油供应的取尽威胁的石油危机引起了更新的兴趣在石油替补的生产上从煤炭在80 年代期间。但是, 象论点为煤炭气化, 低廉石油和天然气供应的宽可及性在90 年代有效地杀害了这些技术的近期商业远景。
