废轮胎热解油浮选性能的试验研究

In order to discuss the flotation property of pyrolysis oil when it used as collector of coal slime, use pipe furnace pyrolysis waste tyre oil, select the temperature section 400℃-600℃.Use the FT-IR analyzes the functional group of the oil, pyrolysis analysis showed that the oil contains aromatics, hydrocarbon alkyl and some polarity material, this provide reasons of pyrolysis oil used as coal slime collector. Use pyrolysis oil as the collector of coal slurry flotation test, the test result indicated that: pyrolysis oil with strong performance when it as coal slime collector, can be used as coal slurry flotation reagents.
