- W2606461698 abstract "For studying the reduction mechanism of iron pyrite with hydrogen this process was investigated kinetically within the range of 460-550°C, by measuring continuously the weight loss of the samples with a quartz spring balance and by analysing the change of phases in the course of reduction with X-ray diffraction method. Although the rate of reduction is approximately proportional to the fraction of pyrite remaining to be reduced at the initial step of reaction, the relationship characteristic of a first order reaction deviates with time and the rate constant increases gradually. This tendency becomes remarkable at about 60% decomposition. Identification of the phases was accomplished by taking X-ray photograms of powdered samples in the course of reduction, using characteristic FeKα radiation in a Debye camera. X-ray diffraction patterns of the samples indicate the following results: In the course of reduction of FeS2, at first, FeS1.15 phase is separated to give a diphasic system. As long as FeS2 exists, no FeS phase is detected. After FeS2 phase has disappeared by reduction, the decomposition of FeS1.15 phase to FeS takes place. Consequently, the reduction mechanism of FeS2 can be represented as follows:(This article is not displayable. Please see full text pdf.) oindentwhere FeS1+x corresponds to FeS1.15. From the fact that no FeS phase appears in the presence of FeS2 phase, it is concluded that the reaction (2) proceeds fairly rapidly in comparison with the other reactions. The increace in the rate of reduction can be attributed to the reaction caused by FeS1.15 phase according to the equation (2) and (3)." @default.
