Characteristic and utilization of pyrolysis productions from Dianchi Lake’s sediment in Yunan province in China

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.
