英文摘要： In view of the dehydration upgrade process of the lignite mild pyrolysis and the necessary links to enhance the value of the lignite industry of high water and mineral ShengLi lignite, while the gaseous products which are closely related to the dehydration upgrade process of the lignite mild pyrolysis and coal composition is a key component of lignite mild pyrolysis ,thus, the study Committed to the gaseous product formation mechanism and intrinsic activity of mineral catalysis / inhibition effect from specific chemical structure and composition of the high mineral ShengLI lignite. Sequential chemical extraction, ion exchange, organic solvent extraction and chlorination, sulfonation, hydrolysis and other coal sample processing, combined with the FTIR and other characterization methods were adopted to Processing and characterization ShengLi lignite, the aim is to determine the type of inherent minerals, occurrence, and occurrence volume and oxygen-containing functional groups, non-aromatic ring structure of side chain, the bridge bond and the low molecular weight organic compounds qualitative and quantitative analysis. On this basis, the use of thermal mass spectrometry and fixed bed online chromatography technology, various types of gaseous products generated dynamics and the formation mechanism of mild pyrol
