Abstract

A multi-stage product gas generation system converts a carbonaceous material, such as municipal solid waste, into a product gas which may subsequently be converted into a liquid fuel or other material. One or more reactors containing bed material may be used to conduct reactions to effect the conversions. Unreacted inert feedstock contaminants present in the carbonaceous material may be separated from bed material using a portion of the product gas. A heat transfer medium collecting heat from a reaction in one stage may be applied as a reactant input in another, earlier stage.

Claims14

Dependent claims

A particulate classification vessel (A1A, A1B) having an interior (INA, INB) and comprising:

(i) a mixture input (A5A, A5AA);
(ii) a classifier gas input (A6A, A6AA) connected to a source of classifier gas (A16A, A16AA);
(iii) a bed material output (A7A, A7AA);
(iv) a contaminant output (A9A, A9AA);
and
(v) a gas distributor valve (V91) configured to separate the classifier interior (INA, INB) into a classifier zone (INA1) and a gas distribution zone (INA2);
wherein:
the gas distributor valve (V91) comprises a valve body (504) and a blade (502) slidable relative to the valve body (504);
the blade (502) has perforations (514) at a first portion thereof;
an actuator (506) is connected to the blade (502) and configured to selectively slide the blade (502) between:
a closed position in which the perforations (514) are located within the vessel, between the classifier zone (INA1) and a gas distribution zone (INA2);
and
an open position in which the perforations (514) are no longer located within the vessel, between the classifier zone (INA1) and a gas distribution zone (INA2).
