Reagent generation for chemical analysis assisted by ultrasonic irradiation
(Elsevier, 2004)
Few methods, such as coulometrics, have been developed to produce reagents in situ for analytical purposes. In this work the
concept related to the generation of ultrasound-assisted reagents was exploited to yield oxidizing ...
Estudo técnico-econômico preliminar da produção de ciclo-hexano pelo método IFP de produção
(Universidade Federal de São CarlosUFSCarCâmpus São CarlosEngenharia Química - EQ, 2022-09-13)
Cyclohexane is a non-polar cycloalkane and highly combustible, which has as main application the production of adipic acid, and nylon 6 and nylon 6,6, polymers that are important to textile industry, thread fabrication, ...
Monitoramento da hidrogenação industrial do óleo de soja empregando cromatografia gasosa, espectroscopia de infravermelho médio e análise multivariada
(Universidade Tecnológica Federal do ParanáCampo MouraoMedianeiraBrasilPrograma de Pós-Graduação em Tecnologia de AlimentosUTFPR, 2015-10-23)
The oils and fats industry routinely get a large amount of data during its operational routines. One of the main parameters used to control the hydrogenation process is the iodine value (IV) which quantifies the relative ...
A dedicated setup for the measurement of the electron transport parameters in gases at large electric fields
(ELSEVIER SCIENCE BV, 2010)
Electron transport parameters are important in several areas ranging from particle detectors to plasma-assisted processing reactors. Nevertheless, especially at high fields strengths and for complex gases, relatively few ...
Regeneration of Activated Carbon by (Photo)-Fenton Oxidation
(AMER CHEMICAL SOC, 2010)
This work aims to study the adsorption of phenol on activated carbons (ACs) and the consecutive in situ regeneration of carbon by Fenton oxidation. Two different operations have been carried Out: (1) a batch procedure in ...
Comparação entre os métodos de determinação de índice de iodo para gordura de soja parcialmente hidrogenada
(Universidade Tecnológica Federal do ParanáCampo MouraoBrasilDepartamento Acadêmico de AlimentosEngenharia de AlimentosUTFPR, 2017-12-06)
The hydrogenation process is very important in the manufacture of by-products of soybean oil, and is intended to reduce the degree of unsaturation to increase oxidative stability and melt temperature. The control of the ...
Global stabilisation of continuous bioreactors: Tools for analysis and design of feeding laws
(Pergamon-Elsevier Science Ltd, 2018-03)
This work revisits the dynamic behaviour of stirred continuous reactors in which a single bioreaction with unknown kinetics occurs. Conditions on the feeding strategy to avoid washing out the biomass and falling in batch ...
Estudo da aplicação do aterramento ressonante em redes de distribuição com ramais monofásicos e bifásicos
(Universidade Federal de Minas GeraisUFMG, 2012-03-23)
The continuous search for better reliability indices in the power supply and the financial losses in the industrial processes, arising from power grid shutdowns, are among the reasons which make utilities and major industries ...
Clavulanic acid production processes in a tower bioreactor with immobilised cells
(Elsevier B.V. Sa, 2008-04-01)
The feasibility of using Streptomyces clavuligerus ATCC 27064 bioparticles supported on alginate gel containing alumina to produce clavulanic acid (CA) was investigated. To this end, effectiveness factors for spherical ...
