Research Description: Landfill gas (LFG) is increasingly used and proposed for a variety of traditional and proposed Waste-to-Energy (WTE) technologies. A challenge for all of these processes is that carbon dioxide (CO2) is produced in similar quantities as methane (CH4), the primary energy carrier. As a result, the lowered energy content either hampers the performance of the WTE process (e.g., electricity generation) or necessitates purification. The high costs of purification is especially prohibitive for production of compressed natural gas (CNG) and pipeline quality natural gas, due to the stringent purity specifications.

Scope of work: In this work, we propose to develop an efficient, low-cost adsorbent for CO2 removal from biogas. Amine-immobilized silica adsorbents are anticipated to be highly selective for CO2 removal from methane and require minimal energy input for regeneration. The amine and silica structure will be evaluated on the performance, in terms of selectivity, regeneration ability, and stability. The results of the experimental studies will feed into a techno-economic feasibility study (with and without carbon capture) in the context of using landfill gases for energy recovery purposes including CNG, power, or liquid fuels. Subsequent efforts (Part 2) beyond this currently proposed work would focus on carbon capture from gaseous emissions from WTE processes and the cost of CO2 recovery and sequestration. The proposed effort leverages previous and ongoing efforts on research and demonstration of LFG to diesel fuel through thermochemical catalytic processes, contaminant removal from LFG, and economic and environmental impact from WTE technologies, which have been funded by the Hinkley Center, Florida Energy Systems Consortium (FESC), the Department of Energy, VentureWell and T2C-Energy, LLC.
