| titleOfInvention | Adsorbent capable of adsorbing oily sludge and application thereof |
| abstract | The invention belongs to the technical field of oilfield sludge adsorption, and particularly relates to an adsorbent capable of adsorbing oily sludge and application thereof. The adsorbent is prepared by the following method: firstly, adding bentonite into an acid solution for activation, fully mixing the activated bentonite and a surfactant for chemical modification, then further carrying out a cationic organic matter graft modification reaction, and drying after the reaction is finished to obtain the adsorbent. According to the invention, the bentonite is selected as a raw material, the specific surface area of the bentonite is increased by modifying the bentonite, and the adsorption charges are added, so that the bentonite can fully adsorb crude oil and other toxic and harmful components in sludge, when oily sludge with the oil content of 20-30 wt% is treated, the addition amount of the adsorbent is 10-20 wt%, the oil content in the oily sludge can be reduced by more than 80%, and the treated sludge with the oil reaching the standard can be further recycled after being fully cured. |
