Fluid bed reactor having vertically spaced apart clusters of heating conduits
First Claim
1. A method of converting a carbonaceous material into a product gas, the method comprising:
- providing a fluid bed reformer comprising;
a reaction vessel defining a compartment suitable for receiving carbonaceous material;
a first cluster of heating conduits at least partially occupying said compartment and extending over a first vertical extent within the compartment, each heating conduit in the first cluster configured to transfer heat from a heat source to the compartment, the heating conduits in the first cluster having a first thickness; and
a second cluster of beating conduits at least partially occupying said compartment and extending over a second vertical extent within the compartment, each heating conduit in the second cluster configured to transfer heat from a heat source to the compartment, the heating conduits in the second cluster having a second thickness, the second cluster of heating conduits being positioned vertically above the first cluster of heating conduits and spaced apart therefrom by a first separation distance, the first separation distance being at least as large as the smaller of the first and second thicknesses, the first separation distance defining a zone in the reaction vessel between the first cluster and second cluster that is configured to be conducive to good solids circulation;
introducing a fluidization medium into the compartment;
introducing carbonaceous material into the compartment in a region that is vertically between the first and second clusters of heating conduits; and
controlling a reaction in the reaction vessel such that at least a portion of the carbonaceous material is converted into a product gas in a fluidized bed.

Abstract
A fluid bed reactor is configured to process a reactive material to form one or more products. The reactor includes a reaction vessel defining a compartment configured to receive the reactive material. A first cluster of heating conduits at least partially occupies the compartment and extends over a first vertical extent within the compartment. A second cluster of heating conduits partially occupies the compartment and extends over a second vertical extent within the compartment. The first cluster of heating conduits is vertically below the second cluster of heating conduits and spaced apart therefrom by a first separation distance. Feedstock inlets are configured to introduce the reactive material into a region that is vertically between the first and second clusters of heating conduits. The heating conduits in the first cluster have a first thickness while the heating conduits in the second cluster have a second thickness. The first separation distance is at least as great as the smaller of the first and second thicknesses.
