D 006-Ⅱ型阳离子交换树脂催化剂在轻汽油醚化装置上的应用

Application of D 006-Ⅱcation exchange resin catalyst in light gasoline etherification unit

介绍了D 006-Ⅱ型阳离子交换树脂催化剂在中国石油玉门石油炼油化工总厂15万t/a催化轻汽油醚化装置上的应用情况,并对该催化剂稳定运行1 a后,装置运行状况进行了标定。结果表明:与混合原料相比,醚化轻汽油产品碳五、碳六叔碳烯烃质量分数分别降低为0.95%,0.96%,碳五、碳六叔碳烯烃总转化率分别为92.52%,65.59%,均高于设计值(85%和55%)要求;烯烃质量分数降低了16.95个百分点;总醚化物质量分数增至23.78%;甲醇质量分数为0.05%,可满足该炼厂生产国ⅥA汽油调和组分的需求。

The application of D 006-Ⅱcation exchange resin catalyst in the 150 kt/a light gasoline catalytic etherification unit in Refining and Chemical Complex of Yumen Oilfield were introduced and the operation status of the unit was calibrated after the catalyst had been operated stably for 1 a.The results showed that compared with blended feed,the mass fractions of C_(5) and C_(6) were reduced to 0.95%and 0.96%and the total conversion rates of C_(5) and C_(6) were 92.52%and 65.59%,respectively,which were higher than the design value(85%and 55%)requirements,the mass fraction of olefin had decreased by 16.95 percentage points,the mass fraction of total etherides had increased to 23.78%,and the mass fraction of methanol was 0.05%,which could meet the the requirements of nationalⅥA gasoline blending components and be used as blending components in Yumen refinery.
