PNNL

Abstract

This project was a collaboration between PNNL and LanzaTech, Inc. to leverage expertise in China in the production of advanced biofuels. LanzaTech has recently developed a novel path involving CO fermentation that converts CO gas, with or without H2, to 2,3-butanediol (BDO). The objective of the project was to develop thermochemical processes to convert the BDO to jet and diesel fuels so that an integrated process to convert syngas to infrastructure compatible transportation fuels could be designed. The primary focus was on the production of isoparaffins (similar to synthetic paraffinic kerosene), but routes to aromatic fuels were also evaluated.
