Coal resources have been used to produce liquid transportation fuels by several process routes collectively referred to as coal liquefaction or, more generally stated, as coal to liquids (CTL). Early records of coal conversion to liquid fuel date to 1913 and an extraction process developed by Friedrich Bergius in Germany [ 7 ].

The first commercially available liquefaction process was the Bergius process, developed in Germany as early as 1911 but brought to commercial scale during World War I. This involves mixing coal in an oil recycled from a previous liquefaction run and then reacting the mixture with hydrogen under high pressures ranging from 200 to 700 atmospheres.

The beginning of the history of synthetic fuels datesgaso to 1913 when the first process of direct coal liquefaction (DLC) by mean of hydrogenation was patented in Germany by the chemist Friedrich Karl Rudolf Bergius () The basic principle of DLC was the use of coal instead of petroleum/crude oil to obtain liquid hydrocarbons used for fuel or as a base for producing other chemicals.

Quick Reference. A process for making hydrocarbon mixtures (for fuels) from coal by heating powdered coal mixed with tar and iron (III) oxide catalyst at 450°C under hydrogen at a pressure of about 200 atmospheres. In later developments of the process, the coal was suspended in liquid hydrocarbons and other catalysts were used. The process was ...

After decades of research, the Bergius process, SRCI, SRCII, costeam process, and Hcoal process have proven to be efficient and costeffective to produce synfuel from direct liquefaction [16]. The main difference between SRCI, SRCII, and Hcoal is the addition of hydrogen and catalysts during the liquefaction phases.
