Research ArticleOpen accessEvery word in the titleCharacterization of Solid Residues Obtained from Supercritical Ethanol Liquefaction of Swine ManureRui Li, Bo Zhang, Shuangning Xiu et al.Animal wastes are considered as renewable energy resources, which contain a great energy potential. For this study, swine manure was treated with supercritical ethanol within the reaction temperature range of 240-360°C to produce bio-oil, resulting in a significant amount of solid residues. Solid residues were characterized by using Fourier Transform Infrared (FT-IR), Scanning Electron Microscopic (SEM), surface area, elemental and … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 4 · 15 Jul 2015 · 7,687 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleSupercritical Ethanol Liquefaction of Swine Manure for Bio-Oils ProductionShuangning Xiu, Abolghasem Shahbazi, Lijun Wang, Carlington W. WallaceProblem statement: Environmental problems associated with animal waste are the most critical challenges faced by the US intensive confinement livestock industries. There is an import and urgent need to develop an efficient way to reduce the pollution of animal waste while extracting valuable energy. Supercritical liquefaction processing of swine manure into a liquid fuel was considered as a cost-effective approach … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 2 · 30 Jun 2010 · 8,245 accessesView PDF Cite

Research ArticleOpen accessIn the abstractStudy of Supercritical Coal Extraction in Toluene Containing FluidsPeter Nikolayevich Kuznetsov, Svetlana Mikhaylovna Kolesnikova, Ludmila Ivanovna Kuznetsova, Anastasia Valerievna KazbanovaThe conversion of brown coals and sapropelic coal in toluene containing mixtures with co-solvents (water, ethanol and tetralin) was studied under sub- and supercritical conditions within the temperature range of 375-550°C and at pressures from 7 to 40 MPa. It was found that the extent of coal extraction in the toluene solvent medium, at 400°C, was significantly increased by the … …American Journal of Applied Sciences, Vol. 13, Issue 3 · 1 Mar 2016 · 7,610 accessesView PDF Cite
