The production of acrylonitrile by using the process of propylene ammoxidation generates an effluent which contains acrylonitrile, acetonitrile and hydrocyanic acid and has an enormous adverse impact on the environment and human health. Circulating fluidized bed (CFB) incineration is an effective, well-improved and widely used method for the disposal of this hazardous material. In China, oil shale is an important source of energy alternative to oil and is rich in reserve. In this study, oil shale is utilized as fuel in the CFB test bed. The acrylonitrile effluent is injected into the furnace to be incinerated for the harmless disposal. The trial demonstrates that at 750 and 850 degrees C, respectively, the concentration of both acrylonitrile and acetonitrile in the flue gas meets Chinese national emission standards. However, the concentration of hydrogen cyanide does not conform to the standard, which problem needs to be further addressed.
