摘要:通过高分子自组装制备高效可回收的纳米反应器代表了绿色有机转化的有前途的策略.在这项研究中,小分子催化剂4-(n,N-二甲基氨基)吡啶(dmap)官能化的纳米反应器是通过在疏水性嵌段中具有dmap部分的两亲性嵌段共聚物的自组装而构建的,从而形成了在水中具有优异分散性的非均相催化剂.关键的制备路线包括2-(n-甲基-N)的可逆加成-断裂链转移(raft)聚合-使用聚(低聚(乙二醇)甲基醚甲基丙烯酸甲酯)(poegma)作为亲水性大分子raft试剂的甲基丙烯酸-(4-吡啶基)氨基)乙酯(mapma)和甲基丙烯酸甲酯(mma).通过动态光散射(dls)和透射电子显微镜(tem)表征表明,纳米反应器具有直径约110 Nm的核-壳纳米结构.所得的聚合物纳米反应器显示出优异的催化活性,可将水中的醇酰化.实现了多种酒精的高转化率(> 99%)和出色的产品选择性.纳米反应器的高催化效率可以归因于在受限的疏水

权利人:EXXONMOBIL TECHNOLOGY & ENGINEERING COMPANY
摘要:Provided are marine fuels or fuel blending compositions, methods of making such fuels or compositions and methods of potentially reducing the life cycle carbon intensity of marine fuels or a fuel blending compositions. The marine fuel or fuel blending composition disclosed herein includes at least 20 vol % of a resid-containing fraction, and from 5 vol % to 80 vol % of one or more renewable fuel blending components. The one or more renewable fuel blending components includes one or more fatty acid alkyl esters. Optionally the one or more renewable fuel blending components may include gas-to-liquid hydrocarbons from renewable synthesis gas, hydrotreated natural fat or oil, hydrotreated waste cooking oil, hydrotreated tall oil, pyrolysis gas oil, or combinations thereof. Optionally, the resulting marine fuel or fuel blending composition can have a BMCI−TE difference value of 15 or less.
