摘 要：In this paper, the spent Activated Carbon (AC) which came from caramel plant was regenerated by the method of microorganism and chemistry. The optimal regeneration method was the combination of microorganism regeneration and NaOH regeneration. The optimal regeneration condition was treated by microorganism in 60 min at temperature of 35 ℃ and in NaOH (dosage was 6%). The optimal ultrafine grinding time was 5 h at 1200 rpm by adding 5 ‰ Triethanolamine, the effect of ultrafine grinding was better and the minimal size distribution was D90 3.82μm, D50 1.62 μm. the study ofAC surface modification was explored while combining the similar characteristics of AC and Carbon Black in its structure and composition. The possibility of reusing the spent AC was studied and the mechanical performance of rubber with modified AC was 434% higher than that of unmodified AC. The modified AC was characterized by Scanning electron microscope (SEM).
