Abstract: By the method of literature research, we summarized the present application situation of TA, IR, XRD, XPS, SEM, NMR and pore size and specific surface area analysis technology applied in coal low temperature oxidation experiment research. With the appearance of new testing and analyzing technology, and modern technology going into deeper and wider fields, we should enlarge its application breadth and depth under the help of the new technology, which can provide more convenient means and methods for the experimental research.
