Synthesis and Characterization of Phenol-Formaldehyde Resin Coated Graphitized Needle Coke
Phenol-formaldehyde (PF) resin coated graphitized needle coke was synthesized by mixing graphitized needle coke with PF alcohol solution, stirring for a long time and then drying. Different processes of direct drying and drying followed filtration were performed to see the effect of coating. The coated materials were also carbonized, graphitized and then characterized. Experiment showed that filtration before dryness process can lead to uniform coating. The concentration of PF resin had an important effect on the coating amount of PF resin. When the PF resin concentration was 30% (wt%), the content of PF resin coated could possibly attain 15% (wt%) for the most. After carbonization, only small amount of carbon residue from PF resin was left which did not affect the crystal structure of graphitized needle coke.
