Title:
METHOD FOR PRODUCING LOWER OLEFINS, REACTOR FOR THE PYROLYSIS OF HYDROCARBONS AND DEVICE FOR QUENCHING PYROLYSIS GASES
Document Type and Number:
WIPO Patent Application WO/1999/043765
Kind Code:
A1
Abstract:
The present invention relates to a method for producing lower olefins by the pyrolysis of hydrocarbons, wherein said method comprises the following steps: heating and evaporating the starting raw material; mixing the same with a gaseous diluent; performing a thermal pyrolysis in a vaned reactor using the heat which is generated in the mixture volume by the hydrodynamic braking action of the vanes rotating therein; and cooling down the pyrolysis products before separating them. The mixture is heated at the pyrolysis temperature by mixing it with the pyrolysis hot gases circulating in the working chamber of the vaned reactor for a period of time which is negligible relative to the duration of the pyrolysis reaction. This method increases the yield of lower olefins.
