Demonstration of Fuel Cells to Recover Energy from Landfill Gas. Phase 2.Pretreatment System Performance Measurement

摘要

The report describes Phase II of a demonstration of the utilization of commercialphosphoric acid fuel cells to recovery energy from landfill gas. This phase consisted primarily of the construction and testing of a Gas Pretreatment Unit (GPU) whose function is to remove those impurities from landfill gas which are detrimental to the fuel cell. The GPU successfully removed the sulfur and halogen compounds contained in the landfill gas to a level significantly below that specified for use with the phosphoric acid fuel cell. During a challenge test in which dichlorodifluoro-methane (Refrigerant 12) was intentionally injected into the process stream during an 8-hour period, the exit concentration of the Refrigerant 12 was below the limit of detection and below the specified value for the fuel cell.
