Abstract:The goal of this study was to minimize the gum content of various viscous biocrude oil samples in order to meet the American Society for Testing and Materials (ASTM) fuel standards. The biocrude oil samples were converted from swine manure via hydrothermal liquefaction (HTL) in a continuous high-pressure high-temperature reactor. Furthermore, this study included the neutralization of these HTL biocrude oil distillates using a hydroxide solution (NaOH) to remove phenolic compounds residing in the samples. The proposed hypothesis was that NaOH would react with phenols found in the biocrude oil samples resulting in a reduction of major compounds found in the gum content. In addition, an orthogonal study was conducted in order to investigate the effects of reaction temperatures (25°C, 35°C, 45°C), reaction time (0.5 hr, 1 hr, 2 hr), concentrations of NaOH (1M, 2M, 5M) and swine manure distillate to NaOH weight ratios (2:1, 1:1, 1:3). After conducting the neutralization of the samples through the orthogonal design experiments, analysis of the composition of the biocrude oil was conducted through the use of a gas chromatography-mass spectrometry machine (GCMS). Results included the discovery of ideal conditions for lowest gum content composition to be a reaction temperature of 45°C, 2 hour reaction time, 2M of NaOH, and a 1:3 weight ratio of NaOH. Ultimately, with promising results the biocrude oil samples prove to be a potential competitor and alternative for petroleum diesel.
