ABSTRACT
In the process of pyrolysis of Dianchi Lake’s sediment, a large number of productions (including gas state, liquid state, and solid state) were obtained. This research analyzed the characteristics and utilization of the representative pyrolysis products by gas chromatography, gas chromatograph-mass spectrometer, Brunauer–Emmett–Teller measurements, and X-ray fluorescence methods. The main gas components were H2, CO, CH4, CO2, C2H4, and C2H6 in pyrolysis productions of the Dianchi Lake’s sediment. The flammable gases, H2, CO, and CH4, were vastly generated at the high-temperature section (>800°C). The main liquid components of pyrolysis products were phenol and hydroxy derivatives, which have no fuel use value, but abundance of phenol and its derivatives can be used as chemical raw materials. Solid products were in the enrichment of Si, Al, Fe, and other mineral elements, which have a good application prospect as building materials.
