Publication number: 20160263771Abstract: A method for removing hazardous air pollutants and contaminants from a wood product is disclosed. In a first step, a contaminated wood product is placed in a treatment vessel. This wood product includes an initial amount of an absorbed contaminant, selected from the group consisting of creosote, a mixture of pentachlorophenol and a carrier oil, a mixture of copper naphthenate and a carrier oil, and combinations thereof In a second step, the wood product is heated to a treatment temperature sufficient to evaporate at least a portion of the absorbed contaminant from the wood product but insufficient to pyrolyze the wood product. The wood product is then maintained at the treatment temperature for a period of time sufficient to reduce the absorbed contaminant in the wood product to a final amount which is less than about 20% of the initial amount. Optionally, the desorbed wood may then be treated with a chemical to remove inorganic impurities that are detrimental during thermochemical conversion of biomass.Type: ApplicationFiled: May 10, 2016Publication date: September 15, 2016Applicants: Nisus Corporation, University of Tennessee Research FoundationInventors: Jeffrey D.

Useful low solubility borates include copper borate, zinc borate and barium metaborate. Useful high solubility borates include boric acid, boric oxide, ammonium borate and alkali metal borates such as sodium borate. Some alkaline earth metal borates, including calcium borates, calcium magnesium borates, magnesium borates and calcium sodium borates, are of intermediate solubility and may be used effectively as either a low soluble or high soluble borate depending on the combination used.Type: GrantFiled: October 22, 2008Date of Patent: February 21, 2012Assignee: U.S. Borax Inc.Inventors: Jeffrey D.
