A method for producing a pelletized carbon adsorbent based on crude petroleum coke activated by potassium hydroxide and petroleum pitch as a binder is proposed. Granules were formed from mixtures prepared in various ratios and carbonized at ~800°C. It was found that the finished product with 30% added pitch retained 60-65% of the effective specific surface area of the used filler (activated coke). Considering the granule crushing strength, an amount of binder from 20 to 30% is recommended so that the specific surface area of the granules will be 600-1100 m2/g.

氢氧化钾活化石油焦颗粒碳吸附剂

提出了一种基于以氢氧化钾活化的原油焦和石油沥青作为粘合剂生产颗粒状碳吸附剂的方法。颗粒由以各种比例制备的混合物形成，并在~800°C 下碳化。发现添加 30% 沥青的成品保留了所用填料（活性焦）的有效比表面积的 60-65%。考虑到颗粒的抗碎强度，建议使用20%~30%的粘合剂，使颗粒的比表面积达到600-1100 m2/g。
