摘要： The invention relates to a method for dehydrating alkanes, wherein the alkane is guided in a reactor for the dehydrogenation of alkanes via a catalyst, and the process may be carried out adiabatically or non-adiabatically, and the catalyst for dehydration can be regenerated after the reaction phase by means of transferring a gas, wherein said gas is guided via the catalyst after a short rinsing phase using water vapor, and said regeneration gas consists of a gas containing oxygen and of steam, and after regeneration the catalyst is freed of the gas containing oxygen by transferring steam, wherein the duration of the transfer of a gas containing oxygen is significantly reduced as compared to common methods and represents 70% or less of the total regeneration time, and the catalyst has an increased selectivity for forming alkene by means of carrying out the regeneration at a constant activity, and the catalyst is comprised of a metal of the group of platinum metals or group VIB of the periodic table of the elements, which is applied to a carrier in form of a compound or in elementary form, which substantially consists of oxides of the elements of tin, zinc, or aluminum.

摘要： A process for the dehydrogenation of alkanes. In several reactors of the adiabatic, allothermal or isothermal type or combinations thereof a gaseous alkane-containing material stream is passed through a catalyst bed in continuous operating mode. The gas stream produced contains an alkene, hydrogen and a non-converted alkane. In order to achieve a constant product composition, at least one of the process parameters of temperature, pressure or steam/hydrocarbon ratio is recorded in the form of measured values at one or several points of at least one of the reactors, where at least one of the process parameters is selectively controlled and influenced such that the composition of the product gas at the outlet of one reactor remains constant throughout the operating period.
