摘要
研究了微波辐照下镍磁黄铁矿空气氧化动力学。结果表明,氧化过程中,物相的转变,物质固有特性对微波的吸收性和化学反应热等因素的影响,致使脱硫反应系非线性升温过程,反应前期和后期分别为化学控制和扩散控制。
The oxidation kinetics of nickel pyrrhotite with air under microwave irradiation has been studied. In the course of oxidation, a nonlinear temperature rising state is caused by the phase tansformation, the microwave absorbility of the samples and the chemical reaction heat. The initial period and the later period of the reaction are under chemical control and diffusion respectively.
