| 摘要 |
The invention relates to a method for the heterogenically catalysed dehydrogenation of one or several C2-C30 hydrocarbons that can be dehydrogenated, in one or several reaction zones, in a reaction gas mixture containing said hydrocarbons. According to said method, at least one portion of the required dehydrogenation heat is generated directly in the reaction gas mixture in at least one reaction zone by the combustion of hydrogen, the hydrocarbon(s) and/or of carbon in the presence of a gas containing oxygen, said reaction gas mixture, which contains the hydrocarbon(s) that can be dehydrogenated, being brought into contact with a Lewis-acidic dehydrogenation catalyst that essentially exhibits no Bronsted acidity. |
