Waste tire recycling process for production of steam activated carbon in a pilot plant

摘要

Highlights?The experimental and numerical results on production of activated carbon by waste.?The surface area has been evaluated varying hold times in steam activation.?The theoretical model shows results in good agreement with the experimental data.?The energy balance was carried out about the experimental tests on pilot plant.AbstractThis work is focused on the production of activated carbon from waste tires by means of a two-steps process: steam gasification of starting material followed by steam activation of char. In particular the evaluation of the most appropriate hold time value for the activation step, in terms of quality and amount of activated carbons produced, and the energy balance of the overall process were performed. The hold time was choose as the best compromise between a high surface area of final product and a not excessively low burn-off value. Investigations were carried out th
