Abstract
Official abstract text for this publication.
A direct carbonaceous material to power generation system integrates one or more solid oxide fuel cells (SOFC) into a fluidized bed gasifier. The fuel cell anode is in direct contact with bed material so that the H 2 and CO generated in the bed are oxidized to H 2 O and CO 2 to create a push-pull or source-sink reaction environment. The SOFC is exothermic and supplies heat within a reaction chamber of the gasifier where the fluidized bed conducts an endothermic reaction. The products from the anode are the reactants for the reformer and vice versa. A lower bed in the reaction chamber may comprise engineered multi-function material which may incorporate one or more catalysts and reactant adsorbent sites to facilitate excellent heat and mass transfer and fluidization dynamics in fluidized beds. The catalyst is capable of cracking tars and reforming hydrocarbons.
First claim
Opening claim text (preview).
What is claimed is: 1. A carbonaceous material gasifier and power generation system, comprising: a reaction vessel having a longitudinal axis (A) extending in a vertical direction and defining a gasifier chamber suitable for receiving a feedstock comprising a carbonaceous material and producing product gas from the carbonaceous material, the gasifier chamber having a fluidized bed and being connected to a source of steam which is in communication with the fluidized bed; a freebo…
