Abstract
A dry feed two stage gasification system and process is disclosed for gasifying feedstock such as carbonaceous materials with improved energy efficiency, along with reductions in feedstock consumption and carbon dioxide emissions. The feedstock is first dried and pretreated with the hot syngas in the upper section of the gasifier to generate a dry char that is low in volatile-matter content. This dry char is sent to the first stage of a two stage gasifier where it reacts with oxygen in the presence of steam to produce a hot syngas stream.
