520 $a The results showed that the thermochemical conversion of swine manure to produce oil is technically feasible. The process could be a promising technology for waste reduction and renewable energy production from organic waste.
520 $a The objective of this thesis work was to explore the feasibility of applying the thermochemical conversion (TCC) technology to the management of swine manure from large confinement swine farms. The TCC process converts swine manure into an oil product and reduce waste strength substantially.
520 $a A batch TCC process was developed. The process parameters including operating temperature, type and initial pressure of process gases, retention time, total solids content, and feedstock pH levels were investigated systematically. The process was evaluated by oil production efficiency and waste reduction efficiency. The oil product was analyzed for its benzene solubility, elemental composition, and heating values. Thermogrametric properties and viscosity were also measured on selected oil samples. The difference of chemical oxygen demands before and after the TCC process was used as the waste reduction efficiency. The key factors of the TCC process were the operating temperature, the retention time, and the addition of a process gas. The operating temperature effect was studied in the range of 275&sim;350°C. The suggested operating temperatures are between 295°C and 305°C. A process gas addition was necessary to achieve an oil product. Without the process gas, no oil products formed. The process gases investigated include carbon monoxide, hydrogen, nitrogen, carbon dioxide, and compressed air. Carbon monoxide was the most effective gas for the process. Retention time is another important factor. The necessary retention time to achieve an oil product was largely related to the operating temperatures. When the operating temperatures were 295°C to 305°C, the retention time was 15&sim;30 minutes. Based on an average of 135 different oil samples, 62%wt of the volatile solids were converted to oil. The waste strength was reduced by 60% to 70%. The highest oil production efficiency was 80%wt. The average carbon and hydrogen contents were as high as 72%wt and 9%wt, respectively. The heating values for 80% of the oil products ranged from 32,000 to 36,700 kJ/kg.
