| titleOfInvention | Method and catalyst for preparing benzene and cyclohexane by catalytically hydrogenating liquid phase of aryl chloride |
| abstract | The invention discloses a method and a catalyst for preparing benzene and cyclohexane by catalytically hydrogenating liquid phase of aryl chloride. The method comprises the following steps: providing a trickle bed reactor filled with a catalyst subjected to reduction treatment; dissolving the aryl chloride into an organic solvent to form an aryl chloride hot solution; and inputting the aryl chloride hot solution and hydrogen into the trickle bed reactor in a liquid phase form and a gas state form so that the aryl chloride hot solution and the hydrogen are subjected to hydrodechlorination reaction under the action of the catalyst to generate a product, wherein the product contains the benzene and the cyclohexane. Furthermore, the product is subjected to gas-liquid separation and distillation refining to obtain a hydrogenated product and the separated organic solvent and hydrogen are circularly used. By virtue of the process disclosed by the invention, the aryl chloride, which is difficult to degrade, is converted into the benzene and the cyclohexane which have the high additional value; the conversion rate of the aryl chloride is high, the side reaction is few, the service life of the catalyst is long and the environmental pollution is little; and the method is a green process capable of changing wastes into valuable things, and has a good application prospect and great economic benefits. |
