Universal feeder with clamshell transfer screw
Exemplary apparatus or method implementations for a universal feeder system configured with a transfer screw feeder within a multi-section clamshell pipe permitting access to the feed screw and pipe interior for inspection, maintenance and/or cleaning during production, without disassembly or screw removal. The clamshell screw feeder pipe provides access to the screw by opening or removing the multi-section top portion of the clamshell pipe. The top pipe section is bolted and or hinges to the bottom portion of the clamshell pipe. The number of segmented multiple clamshell top sections depends on the length of the screw. One or more clamshell top sections may be configured with an inspection port. The universal feeder system configured with a transfer screw feeder within a multi-section clamshell pipe transfers feedstock feed from one or more feed vessels to one or more reactor vessel.
SYSTEM AND METHOD FOR LIQUID FUEL PRODUCTION FROM CARBONACEOUS MATERIALS USING RECYCLED CONDITIONED SYNGAS
A method of producing liquid fuel and/or chemicals from a carbonaceous material entails combusting a conditioned syngas in pulse combustion heat exchangers of a steam reformer to help convert carbonaceous material into first reactor product gas which includes carbon monoxide, hydrogen, carbon dioxide and other gases. A portion of the first reactor product gas is transferred to a hydrogen reformer into which additional conditioned syngas is added and a reaction carried out to produce an improved syngas. The improved syngas is then subject to one or more gas clean-up steps to form a new conditioned syngas. A portion of the new conditioned syngas is recycled to be used as the conditioned syngas in the pulse combustion heat exchangers and in the hydrocarbon reformer. A system for carrying out the method include, a steam reformer, a hydrocarbon reformer, first and second gas-cleanup systems, a synthesis system and an upgrading system.
