1. Oxidation of zinc sulphide concentrate in a fluidised bed reactor - Part 1: Characterization of the fluid dynamics of the particle bed
The oxidation kinetics of a blend of zinc sulphide concentrates in a bench-scale fluidised bed reactor operated in batch regime was studied. This work involves the fluid dynamics characterisation of the bed during the reaction. Its purpose is to determine bed behaviour and to assess the experimental conditions used in the roasting experiments. The characteri

2. Oxidation of zinc sulphide concentrate in a fluidised bed reactor - Part 2: The influence of experimental variables on the kinetics
The oxidation kinetics of a blend of zinc sulphide concentrates in a bench-scale fluidised bed reactor operated in batch regime was studied. The fractional conversion was determined by measuring the SO2 concentration in the exit gas using a chromatograph. The effects of the initial mass of the blend, airflow rate and temperature on fractional conversion were

3. Simulação, projeto e construção de uma unidade piloto multi-proposito para pirolise de residuos
Pyrolysis, one of many solid waste chemical conversion processes, has been receiving a special atenttion from engineers, researches and environment specialists. The pyrolysis has been tested in many pilot plants, and some industrial plants are operated with success. Heating in a controled atmosphere absenced of oxygen, an organic portion of waste materials c

4. ESTUDO FLUIDODINÂMICO E CINÉTICO DA USTULAÇÃO DE CONCENTRADOS DE SULFETO DE ZINCO EM REATOR DE LEITO FLUIDIZADO / FLUID DYNAMICS AND KINETICS STUDY OF ZINC SULPHIDE CONCENTRATES ROASTING IN FLUIDIZED BED REACTOR
This work presents a fluid dynamics and kinetics study of the roasting of zinc sulphide concentrates at 950¢XC. The data were collected in the literature for experiments carried out in an industrial fluidised bed reactor with an excess of oxygen. The theoretical and experimental characterisation was conducted with the operating variables of the industrial r
