AbstractThis study is devoted to developing a continuous activated carbon (AC) production process integrating drying, carbonization, and physical activation without external heat input. The massive byproduct in the distilled spirit industry, distilled spirit lees (SL), was used as the raw material in this study. The kinetic behaviors in each step, including drying, carbonization, and activation, were first investigated via laboratory tests. The results show that the whole AC production process can be completed in 30 min, including most of the time for drying, several minutes for carbonization, and several seconds for activation. On the basis of these laboratory results, an integrated process for continuous production of AC was proposed. The mass and heat balance calculation demonstrated a good balance for the developed process technology, and a pilot plant treating 2000 kg of SL/h was in turn built and commissioned to run autothermally and continuously. This demonstrated thus the technology for application to granular feedstock such as SL, although the produced AC from SL had surface areas of only about 191 m(2)/g and relatively low adsorption values, including 610-630 mg/g for iodine and 20-30 mg/g for methylene blue, due to the too short activation time in the pilot activator.
