| 摘要 |
<p>The invention pertains to a method of non-oxidising dehydrogenation of aliphatic, naphthenic or olefinic compounds implementing a catalyst comprising an active phase comprising a manganese oxide and a silica substrate, the BET specific surface area of said catalyst being between 1 and 500 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 having an oxidisation degree greater than zero, the mass concentration of the active phase allocated to the metallic manganese in relation to the total mass of the final supported catalyst being between 2% and 20% by weight, said method operating at a temperature between 0° C and 750° C, a pressure between 0.1 and 10 absolute bar and an hourly volume speed (V.V.H.) for the hydrocarbon load to be dehydrogenated between 1 and 1000 h-1, in a gas phase and in or not in the presence of water vapour.</p> |
