BA5206 Gasification and synthesis gas processing

Research output: Patent › Patent

Abstract

The invention relates to a method and process arrangement for producing hydrocarbons from plastic containing raw material by means of a gasification process in which the plastic containing raw material is gasified with steam at low gasification temperature of 680-740 degrees centigrade in a fluidized bed gasifier for forming a product mixture comprising hydrocarbons, and the residence time is below 4 s at the gasification temperature, and the product mixture is cooled rapidly after the gasification to temperature which is below 640 degrees centigrade for slowing and/or stopping the gasification reaction of the plastic containing raw material in order to increase propylene yield of the gasification process. Further, the invention relates to the use of the method.
