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.

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.

A device and method for conveying bulk material, said device comprising a movable conveying member and an outer wall that is stationary in relation to the conveying member, wherein the device is connected to a further processing chamber for receiving and further processing the bulk material and a dynamic seal is used which seals with respect to the differential pressure between the further processing chamber and regions lying upstream in the process. A seal element of the dynamic seal formed of a sealant in the form of a material pattern or material seal that can be regenerated during operation of the conveying device, wherein the seal element is provided from a branch flow of the bulk material to be conveyed or from a separate sealant source.

A system for processing solid waste including a segmented gasifier having a first segment detachably connected to a second segment, and a burner positioned downstream of the segmented gasifier and coupled to the segmented gasifier. A process for treating solid waste including introducing the solid waste into a first end of a segmented gasifier having a first segment detachably connected to a second segment. Gasifying the solid waste as it traverses from the first end of the gasifier to a second end of the segmented gasifier, and producing a gaseous output and a solid output at the second end of the segmented gasifier. Separating the gaseous output and the solid output, and introducing a portion of the gaseous output to a burner and recycling a portion of the gaseous output to the segmented gasifier as an energy source.

A gasifier system includes a reactor for receiving a wet feedstock which has a base and a container rotatably connected to the base such that a rotation of the container causes a mixing of the feedstock in an interior of the reactor. The interior is bounded by the base and the container. A space between the base and the container allows an entry of oxygen into the interior. The space has a dimension such that the feedstock is fully oxidized in a combustion area adjacent the base and such that the feedstock avoids combustion in a remainder of the interior. The reactor has a longitudinal axis inclined at an inclination angle relative to a horizontal line to promote the mixing of the feedstock in the interior.
