NETL: CTL and CO2 Capture


 
We present this information, from our own, US, National Energy Technology Laboratory to document that Carbon Dioxide can be directly captured from Coal-To-Liquid conversion facilities.
 
An excerpt:
 
"Pre-combustion CO2 capture relates to gasification plants, where fuel is converted into gaseous components by applying heat under pressure in the presence of steam. CO2 can be captured from the synthesis gas that emerges from the coal gasification reactor before it is mixed with air in a combustion turbine. Here the CO2 is relatively concentrated and at a high pressure."
 
This NETL report relates directly to the conversion (gasification) of coal to syngas, which would then be used, in their scenario, for power generation. However, the coal-derived syngas, instead of being burned in a steam generator, could just as easily be directed into a Fischer-Tropsch reactor and converted into liquid fuel. 
 
Either way, for either use, the Carbon Dioxide generated by the gasification process is captured, and, as we have elsewhere seen, and will see, it can then be used for the synthesis of more liquid fuel.
