Syngas Production by Gasification of Solid Fuels

Suitable coal Non-caking Reactive All All (coal slurry) 

Ash/slag removal Solid Solid Liquid Liquid 

Typical composition of syngas (dry basis) for hard coal as feedstock (vol.%)  

These three reactor types differ with regard to the syngas composition (Table 6.6.2), which is the restdt of different operating temperatures and the amount of oxygen and steam used.

Reactors for syngas production by gasification of solid fuels like coal and probably in future also of biomass are a moving bed, a fiuidized-bed, or an entrained flow system as depicted in Figure 4.10.8 (Section 4.10). Table 6.2.2 lists the main characteristics. Depending on temperature of the gasifier the mineral matter is released as a liquid (slag) or a solid (ash).
