New Technologies for Sustainable Liquid Fuel Production

In this topic, we are looking at the design of new technologies which can help create liquid fuels in a more sustainable way. For example, we are currently developing new syngas cooling technology to be used inside of a downdraft gasifier. Currently, a radiant syngas cooler can be used to cool very hot coal-derived syngas by producing steam. While this helps with thermal management, a significant amount of exergy is lost because the high-temperature heat (1300°C) is not used to its full potential. Therefore, we propose using the natural gas reforming reaction as the coolant mechanism, which produces valuable H2-rich syngas. Not only does this approach result in higher thermal efficiencies and higher profitability, but when properly integrated into a process which produces liquid fuels, results in lower CO2 emissions as well. Other new technologies currently in development include using high-temperature heat from a modular helium reactor to power natural gas reforming, and developing new adsorbents for more efficient syngas treatment and upgrading.
