Research on the Relationship between Changes of Active Groups and Gaseous Products in Different Temperatures

Abstract:

This paper reveals the relationship between the changes of active functional groups in coal and gaseous products. Intelligent coal heating and oxidation trial furnace and GC-4085 series gas chromatograph are used for heating and gas analyzing, then use Fourier-transform infrared spectrophotometer instrument (FTIR) tests the reactive functional groups of coal under different temperatures. Analyzing result shows that: alkane side chains of aliphatic react in the whole process of heating and oxidation. -CH₂-, -CH₂-CH₂- and other bridged linkages crack into free radical groups when they are heated. CO, CO₂ and alkane gases are formed in the reaction. At about 110°C, ethane gas appears; stretching vibration of aromatics, carbonyl acid in the plane and unsaturated hydrocarbon key in aromatic hydrocarbon are relatively stable, which start to react after 140°C with very small amounts of ethylene and propylene gases produced. CO, CO₂ and alkane gases, which are produced by the reaction that peripheral side chains of coal adsorb surface complexes and the gases break away from the coal, are important parts for CO, CO₂and alkane, etc. to generate in low temperature.
