CONTRIBUTIONS TO THE STUDY OF THE MECHANISM AND KINETICS OF NICKEL OXIDES REDUCTION

摘要

The paper is studying the kinetics of nickel reduction from nickel hydroxide in special systems designed for such purpose and the calculation of main kinetic parameters.The reaction order and the values of velocity constant and action energy have been calculated between 250÷550 deg C .The calculation of kinetic parameters wade by integral methods was checked-up by differential methods, which are more appropriate.The purpose of these experiments is to achieve the main kinetic parameters of nickel oxides reduction, being part of an experimental research program, to produce nickel powders.
