The Population Balance Equation (PBE) describe the change in the particle size distribution occasioned by a variety of mechanisms. This study evaluate the PBE with nucleation, growth and dissolution. The nucleation with growth process is known to be problematic due to the sharp pro...

The use of model-based control and optimization systems presents high potential to increase the efficiency and profitability of industrial processes. Therefore, the use and interest in these techniques have grown up steadily. Particularly, the performance of model based systems, as predictive...

In this work, we develop a software that can be used for simulating both P V T properties and asphaltene onset pressure envelope of a reservoir fluid and estimating parameters for fitting both Peng-Robinson and Cubic Plus Association (CP A) equations of state to experimental&#...

Brazilian pre-salt reservoirs represent the discovery of large amounts of light oil, but at high pressures and containing high levels of CO2, being a challenge in its thermodynamic modelling by conventional equations of state (EoS). In order to perform more accurate predictions, it ...

Nickel and nickel phosphide catalysts supported on carbon nanotubes with loading of 10 wt% were synthesized, characterized and evaluated in the hydrogenation reaction of levulinic acid to γ-valerolactone. The catalysts were synthesized in situ by temperature programmed reduction of the precursors...
