中文摘要：

为提高吸油倍率降低吸水倍率,对天然松木屑进行了改性,得到了一种新的除油吸附剂。对该吸附剂的吸油吸水性能进行测定,并确定最佳条件。结果显示：改性木屑吸油效果提升显著,在纯原油中吸油倍率是天然松木屑的2.50倍;吸水倍率降低了80%;漂浮性能好;吸附2 min就能达到吸附平衡,吸附速率是原始松木屑和活性炭的15倍;粒径对改性木屑吸水吸油性能基本无影响;低温和中性条件有利于油的吸附。

英文摘要：

In order to improve the oil adsorption performance of natural sawdust while simultaneously reducing water adsorption,a new oil removal adsorbent was made by modifying natural sawdust material.Then,the adsorption performance of this new material for both oil and water were tested and the influencing factors were evaluated.Results showed that the modified material had a much greater capacity for oil adsorption compared to raw sawdust,i.e.,the new material soaked up 2.5 times more pure oil than unmodified sawdust.Furthermore,compared with raw sawdust,the water adsorption capacity of the new material decreased by 80%.The modified sawdust demonstrated good floating performance,and the equilibrium time for oil adsorption onto the modified sawdust was only 2 min;overall,the adsorption rate was 15 times greater with the new material compared to the rates achieved with raw sawdust and activated carbon.The grain diameter size did not readily affect the adsorption performance for oil/water.Low temperatures and neutral conditions favored the adsorption of oil.
