The present invention relates to a method for conditioning a soot-containing syngas stream in a single integrated apparatus containing a scrubbing vessel wherein particulate matter is decoupled from the waste water stream.

The present invention relates to a process for the purification of raw syngas comprising the steps of (a) contacting the raw syngas with water to remove soot, resulting in a soot-rich waste water and a soot-lean syngas; (b) cooling the soot-lean syngas resulting from step (a) to a temperature in the range of from (20) to (50) C.; and (c) contacting the cooled soot-lean syngas resulting from step (b) with water to remove HCN and NH3 resulting in clean syngas and HCN/NH3-rich waste water, wherein: (i) in step (a) the raw syngas is cooled below its dew point by its contact with water; (ii) the HCN/NH3-rich waste water resulting from step (c) is passed through at least one stripping column resulting in a clean water stream and a waste stream; and (iii) at least 50% (v/v) part of the clean water stream is recycled to step (c).

Processes for producing high biogenic concentration Fischer-Tropsch liquids derived from the organic fraction of municipal solid wastes (MSW) feedstock that contains a relatively high concentration of biogenic carbon (derived from plants) and a relatively low concentration of non-biogenic carbon (derived from fossil sources) wherein the biogenic content of the Fischer-Tropsch liquids is the same as the biogenic content of the feedstock.

The present invention relates to a method for conditioning a soot-containing syngas stream in a single integrated apparatus containing a scrubbing vessel wherein particulate matter is decoupled from the waste water stream.

A CO shift catalyst according to the present invention reforms carbon monoxide (CO) in gas. The CO shift catalyst has one of molybdenum (Mo) or iron (Fe) as a main component and has an active ingredient having one of nickel (Ni) or ruthenium (Ru) as an accessory component and one or two or more kinds of oxides from among titanium (Ti), zirconium (Zr), and cerium (Ce) for supporting the active ingredient as a support. The temperature at the time of manufacturing and firing the catalyst is equal to or higher than 550 C.

A method for processing feedstock is described, characterized in that incoming feedstock is processed to selectively recover biogenic carbon material from the incoming feedstock. In some embodiments the incoming feedstock is comprised of mixed solid waste, such as municipal solid waste (MSW). In other embodiments the incoming feedstock is comprised of woody biomass. In some instances, the incoming feedstock is processed to selectively recover biogenic carbon material from the incoming feedstock to produce a processed feedstock having biogenic carbon content of 50% and greater suitable for conversion into biogenic carbon Fischer Tropsch liquids. The high biogenic carbon Fischer Tropsch liquids may be upgraded to biogenic carbon liquid fuels. Alternatively, the incoming feedstock is processed to selectively recover plastic material from the incoming feedstock to produce a processed feedstock having biogenic carbon content of 50% or less.
