Research Description: We propose a novel process for the upgrading of landfill gas (LFG) to liquid hydrocarbon fuels with a single step for conversion of the methane and carbon dioxide containing feedstock to high value liquid hydrocarbon fuels. In the same reactor, a specially designed and proprietary catalyst will generate syngas, the mixture of hydrogen and carbon monoxide, from LFG and then selectively transform the syngas by Fischer-Tropsch synthesis (FTS) to high value liquid hydrocarbons such as diesel and jet fuel. By incorporating both processes into the same reactor, this effort addresses the key challenge of making LFG-to-liquid fuel technology commercial. Gas-to-liquid fuel technologies are primarily limited by economy of scale and our approach is expected to make a significant impact on this limitation.

Scope of Work: The goals of this project are to design and optimize the single step conversion of LFG to liquid hydrocarbon fuels and to model the impacts of the proposed approach at the process level to assess the economic benefits. The long-term goal of this line of research is to provide an economically viable approach for meeting EPA regulations on landfill emissions. Using the LFG to liquids process, both energy and environmental challenges will be addressed in an economical manner. The proposed effort leverages previous efforts on the demonstration of syngas production from LFG funded by the Hinkley Center and the Florida Energy Systems Consortium (FESC) as well as the design and application of selective FTS (production of diesel and jet fuel) funded by FESC.
