| 发明名称 | Method for selective hydrogenation of phenylacetylene using composite bed in the presence of styrene | ||
| 摘要 | The present invention discloses a process for the selective hydrogenation of phenylacetylene in the presence of styrene conducted in a combined bed, which process comprises under hydrogenation reaction conditions, passing a hydrocarbon fraction feedstock containing phenylacetylene and styrene through a combined bed reactor containing a catalyst A and a catalyst B to contact the feedstock with the catalyst A and the catalyst B in turn, wherein the catalyst A is a nickel-based catalyst, the catalyst B is at least one selected from the group consisting of palladium-based catalysts and copper-based catalysts, and a weight ratio of the catalyst A loaded to the catalyst B loaded is from 0.5:1 to 5:1. | ||

| 主权项 | 1. A process for the selective hydrogenation of phenylacetylene in the presence of styrene conducted in a combined bed, which process comprises under hydrogenation reaction conditions, passing a hydrocarbon fraction feedstock containing phenylacetylene and styrene through a combined bed reactor containing a catalyst A and a catalyst B, wherein the hydrocarbon fraction feedstock contacts with the catalyst A first and then the catalyst B, wherein the catalyst A is a nickel-based catalyst, the catalyst B is at least one selected from the group consisting of palladium-based catalysts and copper-based catalysts, and a weight ratio of the catalyst A loaded to the catalyst B loaded is from 0.5:1 to 5:1. | ||
