Abstract

In dual fluidized bed gasification technology, the gasification/pyrolysis and combustion reactions are decoupled and conducted in two separate fluidized bed reactors connected by circulating inert or catalytic bed material. Hence, a nitrogen-free high-quality syngas is produced. The configuration obviates the need of a capital-intensive air separation unit. It is a complex reactor system, and the challenge lies in selecting appropriate bed material/catalyst, understanding flow patterns and heat transfer characteristics, and designing and operating such a system. This chapter reviews the basic concept, critical components, hydrodynamics, and process characteristics of this technology presenting the current state of the art.
