Carbothermic Reduction of Zinc Containing Industrial Wastes: A Kinetic Model

A KINETIC STUDY ON THE CARBOTHERMIC REDUCTION OF ZINC OXIDE FROM ELECTRIC ARC FURNACE DUST

In the present study, reduction of zinc oxide from the pellets made of steelmaking electric arc furnace dust has been investigated. Effects of such parameters as the type of carbon material (graphite, coke and charcoal) as well as time and temperature on the reduction reaction have been examined. The reduced (dimensionless) time method was applied to perform a kinetic analysis of the system. Ex...

Dielectric properties and carbothermic reduction of zinc oxide and zinc ferrite by microwave heating

This paper aims to study the dielectric properties and carbothermic reduction of zinc oxide (zincite, ZnO) and zinc ferrite (franklinite, ZnFe2O4) by microwave heating. To achieve this aim, the dielectric properties were measured with an open-ended coaxial method to understand the behaviour of the samples under microwave irradiation. The effects of microwave power, duration time and sample mass...

Kinetic Study of Barite Carbothermic Reduction in Presence of Sodium Carbonate as Catalyst

AUDIT AND REDUCTION MANUAL for INDUSTRIAL EMISSIONS AND WASTES UNIDO

This is the seventh publication in a new Technical Series that regroups the Guidelines, Overviews, Technical Reviews and Workshop Proceedings previously published by UNEP/IEO. The regrouping into a single series will ensure a greater cohesion among future publications, and allows a single document to include the various elements of IEO work that had earlier been presented separately. As before,...

A Multiscale Model for Conceptual Design and Simulation of a Carbothermic Reduction Process for Aluminium Production

Multiscale modeling is a tool aimed at combining mathematical descriptions of different process scales into a single, properly tailored scale integration hierarchy allowing for reliable modeling and simulation. This concept has already been successfully applied in deriving accurate state variable distributions for processes that exhibit full spatiotemporal variation and thus do not allow for th...
