Technical research of pyrolytic carbon black prepared on rotating moving bed equipment

Abstract

Nowadays, waste tires have been one of the worst environmental pollution sources. How to solve the waste tires is a hot potato for the environment. Pyrolysis is one of the most commonly used method. In China, rotary kiln reactor has been widely used for pyrolysis and can be used as a large-scale production equipment form, but there is no mature case of rotating moving bed. In this paper, CBp was produced in rotating moving bed. The continuous pyrolysis device, rotating moving bed, which is a new type of equipment to replace the batch reactor. Temperature is studied as the most important character in the cracking process. The results showed that the productivity of CBp, Pyrolytic oil and gas were obviously affected by temperature. The oil could improve the compatibility of CBp with rubber, increasing the dispersion in rubber, resulted in the good reinforce property. High temperature causes more groups be detected on the surface of CBp by FT-IR spectrometer. The Payne effect of CBp reinforced NR compound increases with the increasing of pyrolysis temperature.
