WEB1 Introduction. Coal to Liquids (CTL) as well as Integrated Gasifiion 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.
WEBGasifiion is a technological process that can convert any carbonaceous (carbonbased) raw material such as coal into fuel gas, also known as synthesis gas (syngas for short). Gasifiion occurs in a gasifier, generally a high temperature/pressure vessel where oxygen (or air) and steam are directly contacted with the coal or other feed .
WEBMar 1, 2016 · In the first process, crude liquid biooil is first produced and then upgraded by alytic cracking, hydrotreating, and steam reforming (Pham et al., 2014). The other two processes, called inbed and insitu, respectively, are egorized based on the position of the alyst within the reactor (Tan et al., 2013). During the inbed alytic ...
WEBJan 31, 2021 · The ratio of hydrogen to carbon atoms in liquid fuels ranges roughly from to, whereas the corresponding ratio in coal ranges roughly from to 1 (Mantripragada and Rubin 2013). The process of converting coal to liquids involves adjustment of the hydrogen/carbon atomic ratio, and the excess carbon in the coal is .
