Pelletized Carbon Adsorbent Based on Petroleum Coke Activated by Potassium Hydroxide
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 similar to 800 degrees 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 m(2)/g.
