摘要：

Characterization and potential commercial uses of pyrolytic carbon black obtained in an industrial scale waste tire recycling process.Pyrolytic carbon black was produced using a rotary kiln oven with a daily batch capacity of metric tons(MT)and potential commercial uses were evaluated.The Pyrolysis was performed in an inert atmosphere in a temperature range from 400 to 500°C for approximately 8 hours.Inorganic content was approximately 12%(primarily zinc oxide)and sulfur content was approximately 3%.Based upon analysis of particle size and Scanning Electronic Microscopy(SEM images,approximately 40% of the material has a small particle size with properties very close to those of commercial carbon black grades being used as a filler in polymers and as paint pigment.Characterization was made using granulometric analysis,oil absorption number,thermogravimetric analysis,pH analysis,density analysis,calorific value,SEM,X-Ray Fluorescence,and BET surface area.The material presents properties very close to those of commercial semi-reinforcing materials.Further treatments are proposed to improve material properties.
