| 简介 |
Process for the production of aromatic compounds, such as reforming, that uses at least one fixed catalyst bed with a base of platinum and 0.08% rhenium. In said process, before moving onto the bed, the feedstock undergoes a heat exchange with the effluent that is obtained from the process, whereby the exchange is carried out with a pressure drop that is less than 1 bar and a temperature difference that is less than 70° C. The beds are preferably radial and those that are located at the top of the reactor are covered by a cloth layer. The process preferably uses at least two fixed catalyst beds, whereby the first bed (in the direction of circulation of the feedstock) has an Re/Pt ratio by weight that is greater than that of the second bed, and whereby the second catalyst preferably contains at least 0.08% of Re. |
