For the anthracite combustion catalysed by K{sub}2CO{sub}3, the reaction rate constants increaced with the amount of catalyst loading. Catalytic activity decreased with reaction temperatures. The exponential relationship was proposed between activation energies and K{sub}2CO{sub}3 loading. ...

probably becauseoxidationof carbon monoxide, a reaction that is part of the combustion of practically all natural fuels, usually occurs in the presence of hydrogen or hydrogen compounds: the breakdown ofwood,coal,petroleum, etc., during burning produces carbon monoxide, hydrogen, andcompoundsofcarbon...
The reaction of coal spontaneous combustion to produce ethylene is a spontaneous reaction judging by the reaction activation energy. 由反应活化能可知,生成乙烯的反应是一个自发式反应。 terms.shengwuquan.com 5. As the main factor of mine fire, coal spontaneous combustion is treated seriously for fire...
This may be caused by early combustion of the more reactive coal (J coal) in the blend inducing local variation in oxygen concentration gradients around the less reactive coal and consequently affecting the reaction atmosphere and Fe mineral behaviour and interaction. That is to say, for coal ...
Finally, the general methods for modeling coal reaction processes are outlined, and illustrative examples are given with regard to the current situation in the application of these submodels to computer modeling of pulverized and coal bed combustion. 展开 ...
Combustion, a chemical reaction between substances, usually including oxygen and usually accompanied by the generation of heat and light in the form of flame. Combustion is one of the most important of chemical reactions and may be considered a culminati
