| 摘要 |
<p>The invention concerns a method for the non-oxidative dehydrogenation of aliphatic, naphthenic or olefinic compounds implementing a catalyst comprising an active phase comprising a manganese oxide and an alumina substrate, the BET specific surface area of said catalyst being between 1 and 300 m2/g, the total porous volume of said substrate being between 0.1 and 2 m L/g, the manganese element of said active phase being at a degree of oxidation higher than zero, the mass content of the active phase, relating to the metal manganese, with respect to the total mass of the final catalyst on the substrate being between 2% and 20% by weight, said method operating at a temperature of between 0 °C and 750 °C, a pressure of between 0.1 and 10 bar absolute and an hourly space velocity (HSV) for the hydrocarbon feedstock to be dehydrogenated of between 1 and 1,000 h-1, in the gaseous phase and in the presence or absence of water vapour.</p> |
