摘　　要：利用仿岛津TG-1型电子自平衡微量热天平装置,对硫铁矿焙烧过程进行动力学规律探索。研究了温度、氧浓度对FeS_2分解、FeS_2和FeS焙烧速度的影响,求得了反应活化能,建立了本征与宏观动力学方程。The kinetics of pyrite roasting were studied by a thermogravimetric technique with emphasis on the effect of temperature and oxygen concentration on the rates of FeE2 decomposition and FeS2 and FeS roasting. The activation energies were calculated for those reactions and the intrinsic and macro kinetic equations were developed. Practice and Exploration of the Double-Absorption Sulphuric Acid Process Based on Metallurgical Off Gas...........................Cheng Yunsheng ( 19 ) The design of catalytic reaction engineering and selection of heat exchange modes for sulphuric acid production from low concentration metallurgical off gas are discussed in combination of the design of Qilin's sulphuric acid plant. A optimum design option is proposed for metallurgical acid plants.
