Oil adsorbent and process for preparation thereof |
摘要 |
An effective and regenerable oil adsorbent is obtained from a pitch-like substance formed by heat-treating a heavy hydrocarbon oil to such an extent that the volatile matter content thereof is about 10% by weight to about 60% by weight, preferably about 30 to about 50% by weight. By using this oil adsorbent, oil-removing purification treatment of oil-contaminated water can be effectively achieved with economical advantages.
