摘要： Biomass gasification apparatus includes: gasification reaction furnace; upper supply unit configured to supply woody biomass and inert gas from above through feeding hole to furnace; lower supply unit configured to supply mixed gas containing inert gas from below to furnace; sensor configured to detect clogged state in which biomass is clogged in hole; and controller configured to control supply units to regulate upper supply flow rate of inert gas supplied by upper supply unit and lower supply flow rate of inert gas supplied by lower supply unit based on detection result by sensor. When clogged state is detected, controller increases upper supply flow rate to be higher than first flow rate and decreases lower supply flow rate to be lower than second flow rate so that sum of upper supply flow rate and lower supply flow rate is maintained at predetermined flow rate.

摘要： A system and method for conducting high-temperature thermolysis of a waste mixture formed by sewage sludge and wood waste (e.g., creosote-impregnated wooden railway sleepers and utility poles) are proposed. The products of the high-temperature thermolysis may be used to produce thermal energy, electrical energy, carbon black, and liquid fractions which may be used profitably for various purposes.

摘要： A two-step gasification process and apparatus for the conversion of solid or liquid organic waste into clean fuel, suitable for use in a gas engine or a gas burner, is described. The waste is fed initially into a primary gasifier, which is a graphite arc furnace. Within the primary gasifier, the organic components of the waste are mixed with a predetermined amount of air, oxygen or steam, and converted into volatiles and soot. The volatiles consist mainly of carbon monoxide and hydrogen, and may include a variety of other hydrocarbons and some fly ash. The gas exiting the primary gasifier first passes through a hot cyclone, where some of the soot and most of the fly ash is collected and returned to the primary gasifier. The remaining soot along with the volatile organic compounds is further treated in a secondary gasifier where the soot and the volatile compounds mix with a high temperature plasma jet and a metered amount of air, oxygen or steam, and are converted into a synthesis gas consisting primarily of carbon monoxide and hydrogen. The synthesis gas is then quenched and cleaned to form a clean fuel gas suitable for use in a gas engine or a gas burner. This offers higher thermal efficiency than conventional technology and produces a cleaner fuel than other known alternatives.

摘要： The present invention is a process of recycling plastics based on eliminating the need to pre-sort different plastic materials and using physics to separate plastic particles based on the gravitational weight of those particles. Plastics are grounded down into very small pellets using a uniform pressure cylinder with dimples. Then, the small plastic pellets are separated using a float-sink method. Using the float-sink separation method, the plastics can be lifted and organized by density and by gravitational weight from lower densities to higher densities using different gases or liquids with different gravity weights or densities.

摘要： A Fischer-Tropsch (FT) process with a hybrid membrane/PSA configuration provides high component recoveries from FT off gas with minimum power consumption. Synthesis gas from a synthesis gas production zone is reacted in an FT reaction zone forming a liquid stream and an off gas stream. The off gas from the FT reaction zone, which contains hydrogen, carbon monoxide, and methane reactants, is recycled to the synthesis gas production zone. A purge stream from the recycle loop is sent to a membrane separation unit where it is separated into a permeate stream and a residue stream. The residue stream is separated in a pressure swing adsorption (PSA) unit into a fuel gas stream and a second stream. The second stream can be compressed and recycled to the synthesis gas production zone.

摘要： Various aspects provide for a multistage fluidized bed reactor, particularly comprising a volatilization stage and a combustion stage. The gas phases above the bed solids in the respective stages are separated by a wall. An opening (e.g., in the wall) provides for transport of the bed solids from the volatilization stage to the combustion stage. Active control of the gas pressure in the two stages may be used to control residence time. Various aspects provide for a fuel stream processing system having a pretreatment reactor, a combustion reactor, and optionally a condensation reactor. The condensation reactor receives a volatiles stream volatilized by the volatilization reactor. The combustion reactor receives a char stream resulting from the removal of the volatiles by the volatilization reactor.

摘要： 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.
