摘要

一种组合物，包括一由高表面积氧化铝形成且具有一低棱角度颗粒形状之载体；以及至少一催化活性金属，其中该载体具有孔隙、一总孔隙体积及一孔隙尺寸分布；其中该孔隙尺寸分布显示至少二个孔径波峰，每个波峰具有一最大值；其中一第一波峰具有一孔径等于或大于约200奈米之第一最大值，以及一孔径小于约200奈米之第二最大值；且其中该载体之总孔隙体积的大于或等于约5%系包含在该第一孔径波峰内。; and at least one catalytically active metal, wherein the support has pores, a total pore volume, and a pore size distribution; wherein the pore size distribution displays at least two peaks of pore diameters, each peak having a maximum; wherein a first peak has a first maximum of pore diameters of equal to or greater than about 200 nm and a second peak has a second maximum of pore diameters of less than about 200 nm; and wherein greater than or equal to about 5% of a total pore volume of the support is contained within the first peak of pore diameters.
