摘　　要：通过激光粒度分析仪、扫描电镜、漫反射红外光谱和接触角测定等方法,研究了抑尘剂对煅后焦粒径、表面形貌、表面化学结构和表面性能的影响,结果发现,喷洒抑尘剂的煅后焦粒径显著变大,表面有膜层覆盖,这是由于抑尘剂改变了煅后焦的润湿性,增大了表面能,因而更容易发生聚并。The influence of suppressants on particle size, morphology, surface structure and surface properties of calcined petroleum coke was investigated by laser diffraction size analysis, scanning electron microscope, Fourier transform infrared spectroscopy and contact angle. The results showed that the size of calcined petroleum coke after dust suppression increased obviously, and its surface was covered by a membranous layer. The better wet ability and higher surface energy of calcined petroleum coke resulting from spraying suppressants caused the coalescence of calcined petroleum coke.
