Brown Coal Liquefaction (BCL) direct liquefaction process, developed in Japan and taken to pilot scale in Victoria Australia, is under study at three locations: Banko, Berau and Mulia. Pilot scale tests were carried out on Indonesian low rank coal at a 50 tpd pilot plant in Victoria. There is a proposal to build a 3 ktpd or kbbl/day ...
DCL is termed direct because the coal is transformed into liquid without first being gasified to form syngas (which can then in turn be transformed into liquid products). The latter twostep approach, the coal to syngas to liquids route is termed indirect coal liquefaction (ICL). Therefore, the DCL process is, in principle, the simpler and ...
Coalbased fuels are formed from coal gasification (creating synthetic gas from coal) followed by a series of steps to remove pollutants, synthesize the fuels and then separate out the liquids in a process known as FischerTropsch. CTL fuels have several advantages over other alternative fuels.
The challenge for Leigh Creek Energy Limited was to design, build and commission a pilot plant to transform coal from its solid state into a gaseous form and monitor the technical and environmental performance of the process. The insitu gasification process (ISG) produces methane, hydrogen and other valuable components.
The Liquids from Coal (LFC™) process uses mild coal gasification to upgrade lowrank coals to two fuels: a stable, lowsulfur, highBTU solid fuel similar in composition and handling properties to bituminous coal (referred to as processderived fuel, PDFTM) and a lowsulfur industrial fuel oil (referred to as coalderived liquid, or CDL ...
Synthetic fuel or synfuel is a liquid fuel, or sometimes gaseous fuel, obtained from syngas, a mixture of carbon monoxide and hydrogen, in which the syngas was derived from gasification of solid feedstocks such as coal or biomass or by reforming of natural gas . Common ways for refining synthetic fuels include the FischerTropsch conversion ...
Notwithstanding the complexity of FT plants, all XTL ("anything"toliquid) processes, where X = C for coal, G for natural gas, or B for biomass processes, consist of the three main steps illustrated in Fig. : gasification to syngas and gas cleaning/conditioning, FT synthesis, and product in and different available options for biomass gasification (pressure, use of ...
The CO2 Scrubbing Process. CO 2 scrubbing works not by physically scrubbing the coal, but by isolating CO 2 from the other flue gases before they're released into the air. Regardless of what country you live in, unless you reside in a yurt, the electricity powering your home is most likely coming from a power plant.
Coal liquefaction emits more carbon dioxide than liquid fuel production from crude oil. Mixing in biomass and using CCS would emit slightly less than the oil process but at a high cost. State owned China Energy Investment runs a coal liquefaction plant and plans to build 2 more.
Coal liquefaction is a process in which coal is converted into liquid fuels or petrochemicals. There are several processes used to accomplish this task, the two most common being the "indirect route" and the "direct route". [1]
The FischerTropsch process (FT) is a collection of chemical reactions that converts a mixture of carbon monoxide and hydrogen, known as syngas, into liquid reactions occur in the presence of metal catalysts, typically at temperatures of 150300 °C (302572 °F) and pressures of one to several tens of FischerTropsch process is an important reaction ...
Introduction Coaltoliquids (CTL) is a process of producing synthetic transportation fuels from coal, to replace or supplement conventional supplies of diesel oil and gasoline derived largely from imported oil. In the most commonly used CTL technology, coal is first gasified to produce synthesis gas (or syngas) which is subsequently converted ...
Coal can be converted to liquid fuel using either direct or indirect liquefaction. Direct liquefaction isn't used in the because in order to comply with standards, the process prices itself out of practicality.
Brief history of coaltoliquids Coaltoliquids operations are not new technology. The original FischerTropsch process was developed by German researchers. Gasified coal or natural gas was used to produce paraffin wax that was then refined into diesel, naphtha, and liquid petroleum gases, including propane and butane.
Coal to Liquids (CTL) as well as Integrated Gasification Combined Cycle (IGCC) plants take advantage from the conversion of a cheap, fossil fuel like coal into a clean synthetic gas, mainly composed of hydrogen, carbon monoxide, carbon dioxide and other minor species, either to produce Liquid Fuels or Electricity as output.

During this process, coal and solvents are used to prepare a slurry mixture while pressure is added using hydrogen, which is generated from coal or natural gases. The product contains gases, liquids, and a solid residue of coal minerals and carbon. To make the product usable as transportation fuels, it must first be refined, and the solid ...
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 two basic approaches are direct and indirect coal liquefaction, which have the potential to produce liquid fuels from coal (Jiang and Bhattacharyya, 2015). ...

The Chinese Government is pursuing coal to liquids (CTL) projects as part of a national energy policy costing more than 10bn. The two companies driving the technology in China are Shenhua Group Corporation Ltd and Ningxia Coal Industry Co Ltd (Ningmei). Shenhua alone has coal reserves of more than 220bn tons and a production capacity of 60m ...
