Method of producing product gas from multiple carbonaceous feedstock streams mixed with a reduced-pressure mixing gas
First Claim
1. A method for producing product gas from a carbonaceous material, the method comprising:
- (a) splitting a source of bulk carbonaceous material into a plurality of carbonaceous material streams;
(b) providing a supply of pressurized mixing gas;
(c) reducing a pressure of the pressurized mixing gas by between 5 psig to 750 psig to form a reduced-pressure mixing gas;
(d) mixing the reduced-pressure mixing gas with each of the plurality of carbonaceous material streams to form a plurality of gas-laden carbonaceous material streams, each having a carbonaceous material to gas weight ratio that is less than about 50;
1;
(e) transferring said plurality of gas-laden carbonaceous material streams to a first reactor via a plurality of inlets that are circumferentially spaced apart from one another; and
,(f) endothermically reacting the transferred carbonaceous material with steam in a first reactor to produce a first reactor product gas containing char.

Abstract
A feedstock delivery system transfers a carbonaceous material, such as municipal solid waste, into a product gas generation system. The feedstock delivery system includes a splitter for splitting bulk carbonaceous material into a plurality of carbonaceous material streams. Each stream is processed using a weighing system for gauging the quantity of carbonaceous material, a densification system for forming plugs of carbonaceous material, a de-densification system for breaking up the plugs of carbonaceous material, and a gas and carbonaceous material mixing system for forming a carbonaceous material and gas mixture. A pressure of the mixing gas is reduced prior to mixing with the carbonaceous material, and the carbonaceous material to gas weight ratio is monitored. A transport assembly conveys the carbonaceous material and gas mixture to a first reactor where at least the carbonaceous material within the mixture is subject to thermochemical reactions to form the product gas.
