Materials Issues In Thermochemical Production Processing and Utilization Of Bio-OilJames R Keiser Michael P Brady Samuel A Lewis Sr. Raynella M Connatser Michael D Kass and Donovan N LeonardBiomass-derived oils are a renewable resource which offers the potential for replacing a portion of the fossil derived fuels currently in use. However bio-oils are composed of a large number of organic compounds many of which contain oxygen. Some of these oxygenates have been shown to degrade metallic and nonmetallic materials that are candidates for containing and sealing bio-oils in various stages of production processing and utilization.Selected bio-oils have been chemically characterized and laboratory corrosion tests have been conducted to assess the effects of bio-oil on metallic and non-metallic materials. In addition corrosion samples provided for exposure in operating biomass processing systems have been examined following exposure as have degraded components removed from bio-oil production and processing systems. Results of the chemical analyses and sample examinations will be reported.Research sponsored by the U.S. Department of Energy Bioenergy Technologies OfficeAbstract for STG38 - Pulp & Paper
