The preparation of activated carbon from petroleum coke, and the desulfurization performance
Abstract:Activated carbon was not only an excellent adsorbent, characterized by developed porosity and large surface area, but also it had good chemical stability, high mechanical strength,easy regeneration, et a1. It was used extensively in industry, military, chemical engineering environmental protection, and so on. Recently, with the trend of sustainable development activated carbon as an environmental-friendly material, attracted great attention for energy storage and advanced water treatment. There are great influences of original cokes on the pre-oxidation and activation. The petroleum coke possessing small mosaics, small crystals and low volatile component was favorable for the preparation of activated carbon with large specific surface owing to its higher reaction activity.
