| 发明名称 | Silica doped aluminous particulate materials | ||
| 摘要 | A particulate material includes an aluminous material and a silica dopant. The particulate material includes crystallite particles with a crystallite particle size of less than about 10 nm. The crystallite particles are stacked together to form primary particles with a primary particle size of less than about 500 nm. The primary particles are agglomerated together to form secondary particles with a secondary particle size of greater than about 1 μm. The particulate material has a mean pore diameter of not less than 8 nm. | ||

| 主权项 | 1. A particulate material comprising: an aluminous material; and a silica dopant in an amount of 1.5 wt % to 10 wt % based on the total weight of the particulate material, wherein the particulate material includes crystallite particles with a crystallite particle size of less than about 10 nm, wherein the crystallite particles are stacked together to form primary particles with a primary particle size of less than about 500 nm, wherein the primary particles are agglomerated together to form secondary particles with a secondary particle size from about 1 μm to about 8 μm, and wherein the particulate material has a mean pore diameter of not less than 8 nm and a total pore volume of not less than 0.5 ml/g. | ||
