The results showed that syngas components share the same cycles in intermittent coal feed conditions. There is a decrease in H 2 and CO and an increase in tar when the gasifier operates at a lower capacity. The shutdown process took more than 4.4 h and the recovery from a sudden loss of the bed material took more than 2 h.

The Air Products slurry gasifiers use a single-stage, downward-feed, entrained-flow refractory-lined reactor to produce synthesis gas (syngas) from a coal/water slurry (~ 65% in wt) and oxygen (> 95%). The slurried feedstock is pumped to a custom-designed injector mounted at the top of the gasifier. The coal reacts exothermically with oxygen at ...

5.1. Gasification Introduction. Gasification is a technological process that can convert any carbonaceous (carbon-based) raw material such as coal into fuel gas, also known as synthesis gas (syngas for short). Gasification occurs in a gasifier, generally a high temperature/pressure vessel where oxygen (or air) and steam are directly contacted ...

With the one-stage operation, car- bon conversion remained only at 80% and the resulting cold gas efficiency was in the range of 48-50%. When 25% more coal was fed into the second stage gasifier section, the carbon conversion moved upward to reach 90-92%, while the cold gas efficiency shifted to the 65% range.
