|Ø Nitrogen Removal and Energy Recovery from Sewage Sludge by Combined Hydrothermal Pretreatment and CO2 Gasification
|· A combined hydrothermal pretreatment and CO2 gasification process for removal of nitrogen from SS and production of energy via the gasification of the pretreated SS was proposed and investigated.
· 50% of nitrogen could be removed from SS during hydrothermal pretreatment.
· 57% reduction of ammonia emission was found through the proposed system.
· Synergetic effect was found when co-gasifying hydrochar and leaves.
· Cold gas efficiency of the co-gasification process of a 1/1 hydrochar/leaves blend by mass was enhanced to 66%.
|Ø CO2 gasification of woody biomass: Experimental study from a lab-scale reactor to a small-scale autothermal gasifier
|· Autothermal gasification with 15% CO2 addition was conducted in an 8-kW reactor.
· Biochar obtained under CO2 condition had a moderate pH.
· CO2 as gasification oxidant could produce comparable energy to air gasification.
· Carbon conversion and cold gas efficiency were enhanced with CO2 addition.
· Under the same equivalence ratio, less PM was emitted during 15% CO2 gasification.
