| 发明名称 | Naphtha reforming catalyst and preparation method thereof | ||
| 摘要 | A naphtha reforming catalyst, comprising an alumina support and following components with the content calculated on the basis of the support: VIII group metal 0.1-2.0% by weight, VIIB group metal 0.1-3.0% by weight, sulfate ion 0.45-3.0% by weight, and halogen 0.5-3.0% by weight. The catalyst is used in a naphtha reforming reaction without presulfurization and has a high aromatization activity and a selectivity. | ||

| 主权项 | 1. A naphtha reforming catalyst, comprising: a sulfate ion-containing alumina support, and a VIII group metal of 0.1-2.0% by weight, a VIIB group metal of 0.1-3.0% by weight, and a halogen of 0.5-3.0% by weight supported on the alumina support, wherein the alumina support comprises sulfate ions of 0.45-3.0% by weight and a sodium content of 0.008-0.03% by weight, wherein the weight percentages are calculated based on a weight of the alumina support, and wherein, in said catalyst, a ratio of a pore volume of pores with a pore radius between 3 nm and 10 nm to a total pore volume is from 60% to 85%, a ratio of a pore volume of pores with a pore radius smaller than 3 nm to the total pore volume is not more than 36%, and a ratio of a pore volume of pores with a pore radius larger than 10 nm to the total pore volume is more than 2%. | ||
