Abstract: Various example embodiments described herein relate to a method for synchronizing liquid crystal display (LCD) screens. In some examples, the method includes establishing, by a first device comprising a processor, a master/slave relationship with one or more other devices; determining, by the first device, a frequency associated with turning on a first LCD screen on the first device; and sending, by the first device, a signal to each of the one or more other devices, wherein the signal comprises an instruction to turn on an LCD screen on each receiving device at a same time as the first LCD screen.

Abstract: A system and method for processing unconditioned syngas first removes solids and semi-volatile organic compounds (SVOC), then removes volatile organic compounds (VOC), and then removes at least one sulfur containing compound from the syngas. Additional processing may be performed depending on such factors as the source of syngas being processed, the products, byproducts and intermediate products desired to be formed, captured or recycled and environmental considerations.

Abstract: A two-stage syngas production method to produce a final product gas from a carbonaceous material includes producing a first product gas in a first reactor, separating char from the first product gas to produce separated char and char-depleted product gas, and separately reacting the separated char and the char-depleted product gas with an oxygen-containing gas in a second reactor to produce a final product gas. The separated char is introduced into the second reactor above the char-depleted product gas. The solids separation device may include serially connected cyclones, and the separated char may be entrained in a motive fluid in an eductor to produce a char and motive fluid mixture prior to being transferred to the second reactor. A biorefinery method produces a purified product from the final product gas.

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.

Abstract: A solids discharge system (SDS) is configured to separate solids from product gas. The system includes a solids separation device and at least one solids transfer conduit configured to receive solids from the solids separation device. The solids transfer conduit is selectively partitioned into a plurality of compartments (or “sections”) along its length by isolation valves. A gas supply conduit and a gas discharge conduits are connected to one of the sections to facilitate removal of solids. A filter in fluid communication with that section is configured to prevent solids from passing through the gas discharge conduit so that the solids can be removed from one of the sections of the solids transfer conduit. A product gas generation system incorporates first and second reactors, the latter of which receives products created by the second reactor.

Abstract: Apparatuses, systems, and methods of manufacturing are described that provide improved tag identification. An example system includes a radio-frequency identification (RFID) scanner that receives a stream of RFID tags each associated with a respective article. The system further includes a first sensor attached to the RFID scanner that generates first positional data and a second sensor positioned separate from the first sensor that generates second positional data. The system also includes a computing device communicably coupled with the RFID scanner, the first sensor, and the second sensor. The computing device receives the stream of RFID tags, receives first positional data from the first sensor, receives second positional data from the second sensor, and determines an intended RFID tag from amongst the stream of RFID tags based upon the first positional data and the second positional data.

Abstract: 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.

Abstract: A direct carbonaceous material to power generation system integrates one or more solid oxide fuel cells (SOFC) into a fluidized bed gasifier. The fuel cell anode is in direct contact with bed material so that the H2 and CO generated in the bed are oxidized to H2O and CO2 to create a push-pull or source-sink reaction environment. The SOFC is exothermic and supplies heat within a reaction chamber of the gasifier where the fluidized bed conducts an endothermic reaction. The products from the anode are the reactants for the reformer and vice versa. A lower bed in the reaction chamber may comprise engineered multi-function material which may incorporate one or more catalysts and reactant adsorbent sites to facilitate excellent heat and mass transfer and fluidization dynamics in fluidized beds. The catalyst is capable of cracking tars and reforming hydrocarbons.

Abstract: A solids circulation system receives a gas stream containing char or other reacting solids from a first reactor. The solids circulation system includes a cyclone configured to receive the gas stream from the first reactor, a dipleg from the cyclone to a second reactor, and a riser from the second reactor which merges with the gas stream received by the cyclone. The second reactor has a dense fluid bed and converts the received materials to gaseous products. A conveying fluid transports a portion of the bed media from the second reactor through the riser to mix with the gas stream prior to cyclone entry. The bed media helps manipulate the solids that is received by the cyclone to facilitate flow of solids down the dipleg into the second reactor. The second reactor provides additional residence time, mixing and gas-solid contact for efficient conversion of char or reacting solids.

Abstract: A method for calculating the height and the density of a fluidized bed is described. In a first mode of operation, a first differential pressure and a second differential pressure are obtained, a bed density of the fluidized bed is calculated, and a bed height is calculated by dividing the first differential pressure by the calculated bed density. In a second mode of operation the system is purged by using a pressurized gas.

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.
