摘要/Abstract

摘要： 以环烷基油为原料，分别采用萃取法和吸附法脱除原料中有害的多环芳烃化合物（PAHs），得到的抽余油用作环境友好橡胶操作油。实验考察了萃取和吸附、萃取剂的选用和复合使用情况、萃取分离操作条件对脱除效果的影响，同时对抽余油性质进行了改进。结果表明：萃取法脱除效果明显优于吸附法；萃取剂复合使用分离效果更好；在剂油比为2：1，温度为60 ℃，搅拌速度150 r/min，搅拌时间15 mim时，复合萃取剂分离系数高达220.0，二级萃取后PAHs含量从14.0%降低到1.7%，同时改善了族组成分布，经黏度改进后基本满足欧盟环保的VIVATEC500规格标准。抽余油收率在82%以上。

Abstract: Environmental friendly rubber processing oil was prepared from naphthenic base crude feed using extraction or adsorption methods to remove polynuclear aromatic hydrocarbons (PAHs). The comparable experiments between preparation methods were carried out and the results showed that the removal of PAHs by extraction was much better than that by adsorption, thus extraction method was adopted. The effect of various solvents including complex solvent and extracting conditions on the removal of PAHs was investigated, as well as the properties of solvent raffinate. Results indicated that the complex solvent exhibited improved separation effect, its maximum separation coefficient reached up to 220.0 under the following process conditions: a solvent/oil ratio of 2, extracting at 60℃ for 15 min and using stirring speed of 150 r/min. After secondary extraction, the PAHs content in solvent raffinate was reduced to 1.7% from 14.0%. The yield of solvent raffinate was more than 82%, and its hydrocarbon group compositions were improved. By adding certain viscosity improver the quality of the final product could meet the product standard for VIVATEC500 rubber processing oil, which is an environmental friendly product.
