Thermogravimetric kinetics of crude glycerol.
The pyrolysis of the crude glycerol from a biodiesel production plant was investigated by thermogravimetry coupled with Fourier transform infrared spectroscopy. The main gaseous products are discussed, and the thermogravimetric kinetics derived. There were four distinct phases in the pyrolysis process of the crude glycerol. The presence of water and methanol in the crude glycerol and responsibl...
متن کاملCombustion characteristics of bio-oil from swine manure/crude glycerol co-liquefaction by thermogravimetric analysis technology
The thermal analysis and kinetics of bio-oils derived from swine manure/ crude glycerol co-liquefaction were studied by thermogravimetric analysis (TGA) in the air. It was found that the combustion processes of bio-oils can be divided into three stages, with most of the materials decomposing between 330 and 370°C. In kinetic calculations, oxidation of the bio-oils was determined using the Coats...
متن کاملPyrolysis Kinetics of Waste High-density Polyethylene using Thermogravimetric Analysis
Thermal behavior of plastic materials can be improved by knowing thermal degradation kinetics for the optimal design and operation of pyrolysis process. In the present study, thermogravimetric analysis has been used for the non-isothermal kinetic study of waste high-density polyethylene pyrolysis under nitrogen atmosphere at different heating rates 10, 20 and 40 °C/min. The kinetic parameters, ...
متن کاملAnaerobic treatment of crude glycerol from biodiesel production.
In this study, we evaluated the use of an up-flow anaerobic sludge blanket (UASB) reactor to treat crude glycerol obtained from cottonseed biodiesel production. The laboratory-scale UASB reactor (7.0 L) was operated at ambient temperature of 26.5°C with chemical oxygen demand (COD) concentrations between 0.5 and 8.0 g/L. The volatile fatty acid contents, pH, inorganic salt contents and biogas p...
متن کاملBioconversion technologies of crude glycerol to value added industrial products
Crude glycerol that is produced as the by-product from biodiesel, has to be effectively utilized to contribute to the viability of biodiesel. Crude glycerol in large amounts can pose a threat to the environment. Therefore, there is a need to convert this crude glycerol into valued added products using biotechnological processes, which brings new revenue to biodiesel producers. Crude glycerol ca...
