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.

In the case of a device for gasification of carbonaceous fuels, having a discharge for slags into a slag bath, a solution is supposed to be created with which the gasifier discharge opening is reliably kept at a temperature that guarantees that the slag will flow out. This is achieved in that the gasifier discharge opening () is equipped with a ceramic drip edge () that can be electrically heated.
