This paper is aimed at introducing the authors' research of the spontaneous combustion characteristics of iron sulfides as a result of the reactions of hydrogen sulfide to the different degrees of humidity of the iron oxide black, iron oxide red and the iron hydroxide.

The oxidation heat of the iron sulfides is regarded as the main cause of tank fire.

Self-ignition accident by sour oil tank was analyzed,and the major reason was found to be thermal oxidation of iron sulfides generated from reaction of rust with hydrogen sulfide.

Spontaneous combustion tendency of iron sulfide in natural environment;

Oxidation experiment was made on iron sulfide by spontaneous ignition test system to explore the spontaneous combus- tion tendency of iron sulfide in natural environment.

The preparation and catalytic performances for thermochemical decompositionreaction of H_2S to H_2 of several catalysts of iron sulfide were investigated.

Research of functions of detergent YX-LS5 for iron sulfide;

Research on composite cleaning agent of iron sulfide

Synergistic treatment of iron sulfide laden and stabilized slops simultaneously by use of surfactant and denitrifying bacteria was studied.

Lithiated vanadium oxide (LVO) was researched as the cathode material for thermal battery in order to substitute the common used iron disulfide material ,which is characterized by thermal decomposition at high temperature.
