16 Composition of Raw Gas from Different Feedstock Component Unit Hard Pet coke Lignite Domestic Oil Biomass coal refuse Sewage sludge Calorific value (dry) MJ/kg H 2 vol.-% CO vol.-% CO 2 vol.-% CH 4 vol.-% < 0.1 < 0.1 < 0.1 < 0.1 < 0.1 < 0.1 < 0.1 N 2 vol.-% H 2 S vol.-% COS vol.-% < HCN vol.-% NH 3 vol.-% Calorific value MJ/Nm

17 Multiple-fuel feeding Advantage of GSP TM gasification process Lignite, bituminite, anthracite and petrol coke as feedstock due to the high reactive temperature Additional feeding of liquids,slurries,gases or others is possible Flexible operation at different ash contents and composition Especially coal with high ash and sulfur content as well as high ash flow temperature can be gasified. Excellent technical indicators ( depend on different coal) High reaction temperature 1350 ~ 1750 High Carbon Conversion >99% Raw Synthesis Gas without hydrocarbons, i.e. absolutely tar free No dioxin/furan formation despite high chlorine content in the gasification Syngas (CO+H2) content >90% Cold coal gas efficiency >80%

18 Advantage of GSP TM gasification process High availability and low maintenance cost Cooling screen compared to refractory lining Expectation of Cooling screen life time 25 years Expectation of burner (excluding front tip) life time >10 years Short start-up and shutdown time (about 1 hour) High flexible operation: Load flexibility of single gasifier can be adjust from 70% to 110% High auto control level: Process and equipment simple and safety Environmental friendly: slug contained no hazardous substance can used as building materials Short process flow, small equipment, low investment, short building period and low operation cost
