| 摘要 |
The invention relates to an isothermal method for dehydrogenating alkanes to form corresponding alkenes on a catalyst bed containing a dehydrogenating catalyst. Said method is characterised in that the catalyst bed contains a catalytically inactive, inert diluting material. Preferably, said catalytically inactive, inert diluting material is selected from the group consisting of the oxides of the main groups II, III and IV, and the subgroups III, IV and V, the mixtures thereof and nitrides and carbides of elements of the main groups III and IV, and preferably has a BET surface of < 10 m2/g. The presence of the catalytically inactive diluting material in the catalyst bed enables the volume/time yield relating to the alkenes formed to be limited to preferably 7,0 kg/(kgbed x h). |
