2. Fluidodinâmica de leitos fluidizados e vibrofluidizados operando com partículas planas
The use of fluidized beds as a unit operation for drying of particulate materials is common in industrial processes. However, most works published in the literature, focus the drying of uniform particles, in a narrow range of size distribution. The appealing characteristics of fluidization for drying led some authors to suggest its use for drying of particle

3. Estudo fluidodinamico de um leito fluidizado pulsado rotativo com particulas secas e umidas / Rotating pulsed fluidized bed fluidynamics of dry and moist particles
The rotating-pulsed fluidized bed (RPFB) has been studied as an alternative for fluidization of materials that are difficult to operate in the Conventional Fluidized Bed (CFB). The RPFB apparatus is a conventional fluidized bed modified by the addition of a rotating plate with a 60º opening just below the distributor. The rotating plate insures a cyclic fee

4. Estudo do Processo Continuo para ProduÃÃo de AÃucar invertido por via EnzimÃtica / Study of the Process I continue for Production of inverted sugar for saw Enzymatic
A enzima invertase (E.C.3.2.1.26-D-fructofuranosidase) catalisa a hidrÃlise da sacarose produzindo uma mistura equimolar de glicose e frutose denominada aÃÃcar invertido, que possui maior poder edulcorante, Ã mais facilmente adicionada em preparos industriais e possui maior valor agregado que a sacarose. O fungo Cladosporium cladosporioides possui invert

5. Fluidodinamica e secagem do acido adipico em leito vibrofluidizado
The objective of this work is the development and building of a vibrofluidized bed and sampling system for the fluid-dynamic study and drying of adipic acid. The adipic acid investigated in this work presents partic1e diameter in the range of 75 - 600 ?m and density of 1340 kg/m3. Adpic acid is the main intermediate product in the synthesis of Nylon. It is t

6. Estudo do efeito dos parametros fisicos e quimicos de adsorvente solido no processo de adsorção de SO2 em calcario
The process of energy generation, in special, the fluidized bed combustion, is responsible for gas emission to the atmosphere, generating serious enviroment problems. With the aim to minimize this emission, it has been used the solid alkaline injection, usually the limestone, during the fossil fuel bum. The efficiency of the S02 removal process, through the

7. Microscale Distribution of Populations and Activities of Nitrosospira and Nitrospira spp. along a Macroscale Gradient in a Nitrifying Bioreactor: Quantification by In Situ Hybridization and the Use of Microsensors
The change of activity and abundance of Nitrosospira and Nitrospira spp. along a bulk water gradient in a nitrifying fluidized bed reactor was analyzed by a combination of microsensor measurements and fluorescence in situ hybridization. Nitrifying bacteria were immobilized in bacterial aggregates that remained in fixed positions within the reactor column due
