The conversion characteristics of anthracite and bituminous coal were studied under
preheating by a circulating fluidized bed and deep gasification technology, revealing the …

Underground coal gasification (UCG) is a promising technology which in-situ converts coal
into fuel gases through controlled chemical reactions. In order to precisely control coal …

A low-nitrogen pyrolysis atmosphere plays a very important role in the clean and efficient
application of low rank coal. The characteristics of low-rank coal pyrolyzed in a low-nitrogen …

Due to the higher efficiency and more compact structure, pressurized oxy-coal combustion
system is promising in carbon capture and storage. However, coal conversion behaviors, eg …

The H 2 atmosphere exerts an important influence on both the pyrolysis behavior of low-rank
coal and the efficient application of the resultant char. Thermogravimetry-mass spectrometry …

Accurate assessment of the structural characteristics and reactivity of coal char is crucial for
the design of burners. Chars from low-volatile coal were prepared under O 2/N 2 (ON) and O …

Syngas tempering technology refers to highly reactive gases to consume excess O 2 in the
circulating flue gas. An activation environment is created, and the reburning coal is rapidly …
