1. Deep removal of 4,6-dimethyldibenzothiophene from model transportation diesel fuels over reactive adsorbent
This paper presents a new reactive adsorbent used to effectively remove 4,6-dimethyldibenzothiophene (4,6-DMDBT) from model transportation diesel fuels. This reactive adsorbent was composed of formaldehyde, phosphotungstic acid and mesoporous silica gel. The experiment was based on an assumed condensation reaction of 4,6-DMDBT with formaldehyde using phospho

3. Study of the kinetics, the equilibrium and the dynamics of manganese (II) ion biosorption by sargassum filipendula biomass / Estudo da cinética, do equilíbrio e dinâmica de biossorção do íon manganês (II) pela biomassa Sargassum filipendula
O crescente aumento no uso de metais e outros produtos químicos nos processos industriais tem resultado na geração de grandes quantidades de efluentes aquosos que contém altos níveis de metais tóxicos, o que gera sérios problemas ambientais associados ao descarte destes efluentes. O objetivo deste trabalho foi realizar uma investigação da biossorç�

4. 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

5. Separação de ampicilina produzida enzimaticamente por reação entre éster metílico de fenilglicina e ácido 6-aminopenicilânico.
The separation/concentration process of the products obtained from the enzymatic synthesis of ampicillin (AMP) catalyzed by immobilized penicillin G acylase was the focus of this Thesis. Hydrophobic resin adsorption and isoelectric precipitation were the processes herein evaluated. The antibiotic was produced in the solid phase, from 6-aminopenicillanic acid

6. Microbiological aspects of aerobic thermophilic treatment of swine waste.
A thermophilic strain (D2) identified as a Bacillus sp. was isolated from an aerobic digestor of swine waste after several months of operation at 55 degrees C. Aerobic thermophilic batch treatment of swine waste inoculated with strain D2 was studied in a 4-liter fixed-bed reactor. Stabilization of the waste was achieved in less than 30 h when the original ch
