Abstract
The invention relates to a method for producing propylene during which a first gas mixture, which is technically free of oxygen but contains propane, water vapor and hydrogen, and which has a temperature of at least 400° C., is led into a reaction device having at least one catalyst bed as well as usual dehydration conditions. Another gas mixture, which contains propane and oxygen and which can also contain ammonia, the propane content exceeding the oxygen content, is led into the same reaction device in which it reacts with the first gas mixture while forming propylene, water vapor and hydrogen, and the formed gas mixture containing propylene, water vapor and hydrogen is drawn out of the reaction device.
Claims9
A process for the production of propylene from propane comprising the steps of:
- a first gas mixture with a minimum temperature of 400° C., technically oxygen-free but comprising propane, water vapor and hydrogen, is fed to a reaction device having at least one catalyst bed and exhibiting the standard dehydration conditions;
- a further gas mixture containing propane and oxygen and optionally a content of ammonia, the propane content exceeding that of oxygen, is likewise fed to the said reaction device, in which the said mixture reacts with the first mixture, thereby forming propylene, water vapor and hydrogen forming a further gas mixture;
- and
- the further gas mixture thus obtained and containing propylene, propane, water vapor and hydrogen is subsequently withdrawn from the reaction device.
