摘要： Pre-ground plastics of small particle size not more than 2 mm are co-fed into a solid fossil fuel fed entrained flow partial oxidation gasifier. A syngas composition can be made by charging an oxidant and a feedstock composition comprising recycle plastics and a solid fossil fuel to a gasification zone within a gasifier; gasifying the feedstock composition together with the oxidant in said gasification zone to produce said syngas composition; and discharging at least a portion of said syngas composition from said gasifier; wherein the recycled plastics are added to a feed point comprising a solid fossil fuel belt feeding a grinder after the solid fossil fuel is loaded on the belt, a solid fossil fuel belt feeding a grinder before the solid fossil fuel is loaded onto the belt, or a solid fossil fuel slurry storage tank containing a slurry of said solid fossil fuel ground to a size as the size fed to the gasification zone.

摘要： 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.

摘要： A process for the gasification of a solid carbonaceous feed, the process comprising the steps of: introducing a batch of the solid carbonaceous feed into a sluice vessel, while an internal pressure in the sluice vessel is at a first pressure; introducing at least recycled CO2 into the sluice vessel via one or more gas inlets covered by the solid carbonaceous feed, to pressurize the sluice vessel from the first pressure to a second pressure exceeding the first pressure, during a predetermined time period; closing the one or more gas inlets; opening a feed outlet of the sluice vessel to supply the batch of the solid carbonaceous feed to a feed vessel for feeding the solid carbonaceous feed to a gasification reactor; closing the feed outlet; venting the sluice vessel to reduce the internal pressure to the first pressure; and repeating the process.

摘要： A system for gasification of a carbonaceous material and recycling char or solids from a gasifier is disclosed. The recycling system may include a standpipe that receives a solids stream from a separator, the standpipe generating a pressure differential across a bed of accumulated char, thereby producing a bottoms stream having a greater pressure than the inlet solids stream. The recycling system may also include a holding vessel that receives the bottoms stream and a fluidized-bed distribution vessel that receives char from the holding vessel and is configured to provide a continuous and precise flow of recycled char to the gasification reactor.

摘要： The present invention relates to a gasification apparatus and a gasification method, the apparatus comprising: a reactor for gasifying fuel; a fuel supply part for supplying fuel to the reactor; and a dispersion plate for spraying fuel, so as to enhance reactivity in the reactor, and aerosolizing moisture within fuel, thereby uniformly supplying fuel to the reactor, wherein the dispersion plate, in a state of being charged by receiving power, is configured to electrostatically spray fuel and a gasification agent, thereby producing a micro droplet, and atomizing the same. Accordingly, it is possible to aerosolize fuel using a boiling phenomenon or an electrostatic spray phenomenon, and uniformly supply fuel to the reactor. Also, it is possible to obtain the effect of increasing gasification reaction efficiency by preheating and reforming fuel and moisture through mid-low temperature oxidation prior to supplying the same the reactor.
