The present invention demonstrates a continuous process for dry conveying of powdered coal either a blend of carbonaceous material subject to partial oxidization whereby the conveying feed will be transferred via a suitable conveyer from an atmospheric silo to a or a number of extruder's LP Feeder Vessel and be fed over extruder's inlet chute in continuo to a or a number of extruder(s), in which the dry feed material will be densificated along the compression zone of that extruder up to high pressure and will be discharged over outlet chute into a downstream said First Pressurized Vessel, wherefrom the feeding precursor will be transported via a or a number of in series pressurized tubular-drag conveyor to the said Second Pressurized Vessel, which is equipped with one or more Reactor Feeding Unit(s), referred to Splitter(s), each one consisting of a Star Valve, Reactor-Feed-Line and a said Injection-Line for pneumatic conveying individually, whereby the feed carbonaceous material will be exposed to with injection gaseous media (saturated steam, superheated steam, inter gases, natural gas, N2, CO2, purge gas from synthesis section of ammonia, methanol plant, purge gas from PSA of hydrogen purification section, hydrogen or a blend of those gaseous media in any composition) by the formation of any pneumatic bulk conveying mechanism into a downstream pressurized reactor, preferably a gasification reactor, wherein the transported precursor will be converted chemically under high temperature and elevated pressure via partial oxidization reactions to process gas, slag and ash. |
