This work aims at contributing to the preservation of coke oven refractory lining, presenting a planning and control methodology. The condition of the refractory lining of coke batteries is crucial for its productivity and compliance with environmental guidelines. Among the challenges faced there are (i) the early identification of damages with pre...

O aumento da concentração dos gases-estufa, principalmente o dióxido de carbono (CO₂), e as mudanças climáticas tornaram-se assunto científico, econômico e político importante nos últimos anos. O Mecanismo de Desenvolvimento Limpo (MDL) do Protocolo de Quioto concede “créditos de carbono” comercializáveis a projetos que promovam o “sequestro de car...

Experiment Findings
Full-text available
The suitability of a catalytic membrane reactor (CMR) for citronellol, 1-octene and styrene formation from partial hydrogenation was tested. Conversion (X) and selectivity for the desired product (S) were observed for a range of pore sizes of the porous membranes (0.6, 1.8/1.9 and 3.0 μm), catalyst amounts (0.4-31.8 mgPd), hydrogen initial pressure...
Experiment Findings
Full-text available
A mathematical model is presented, which simulates the performance of a forced-through-flow catalytic membrane reactor. It is applied to investigate the hydrogenation of cyclooctadiene. In a first approach, a simplified model, with no regard to consecutive reaction of cyclooctene to form cyclooctane, gives material for preliminary studies. Further...

Conference Paper
Full-text available
Fuel savings have been increasingly climbing the priority agenda of a diversity of companies and the recent development of global economy speeds up the pace. Energy intensive industries are particularly engaged in finding out creative solutions towards efficiency. On addressing the trade-off between shortage of resources and the need for R&D invest...
Presentation
Full-text available
The reactive flow in a catalytic membrane reactor (CMR) has been modeled and simulated through computational fluid dynamics (CFD). In earlier works, the considered CMR – consisted of α-Al₂O₃ tubular membranes impregnated with Pd nanoparticles in a metal shell – had been applied to enhance the selectivity of hydrogenation of 1,5-cyclooctadiene (COD)...
Thesis
Full-text available
This study focused on the development of a model for the flow in a reactor membrane of the type active contactor, approached through computational fluid dynamics (CFD), using the commercial software ANSYS FLUENT. The model included the entire membrane module, consisted of a tubular membrane and a metal shell. The model reaction studied was the part...
Conference Paper

The heating of silica-lined furnaces in the frame of forced convection conditions combines fundamental and complex physical and chemical processes. In this work, a numerical investigation has been performed using CFD calculations, in order to gain more insight in involved processes. This work has been carried out using the capabilities of Glass Ser...
