Biogas vehicle fuel from digested cattle manure.

摘要

The use of anaerobic digestion for waste treatment provides multiple benefits: the production of biogas provides a sustainable renewable energy. This fuel source would reduce the overall farm operation cost by reducing demand for diesel and unleaded gasoline. The biogas used in this study was produced by an Induced Blanket Reactor (IBR) anaerobic digester system. The biogas used in this study contained approximately 65.5% methane, 15.6% carbon dioxide, and 125% trace gases. Biogas chemical composition analysis, hydrogen sulfide analysis, engine performance tests, emission testing, and motor oil analysis were performed. Results indicated that no excess wear or corrosion occurred while operating the vehicle with the biogas mixture fuel. Due to the lower energy content of the biogas, engine performance decreased when compared to gasoline and compressed natural gas fuels.
