Optimization of electric energy consumption in degradation of Indigo Carmine based on a new cylindrical batch suspension photocatalytic reactor designing concerning the main engineering parameters such as mixing, reaction kinetic, mass transfer, catalyst illumination, and inherent potential of contaminant was done. The most degradation efficiency was observed within in air flow rate 1.2L. min-1...

The transition from batch to continuous processes for polyol production presents interesting challenges because of the unusual behavior of double metal cyanide (DMC) catalysts. One feature that is often observed in these catalysts is the need for an activation period whose length changes from one catalyst formulation to another. When this activation occurs in the same reactor where the chain gr...

Continuous flow chemistry as a process intensification tool is well known. However, its ability to enable chemists to perform reactions which are not possible in batch is less well studied or understood. Here we present an example, where a new reactivity pattern and extended reaction scope has been achieved by transferring a reaction from batch mode to flow. This new reactivity can be explained...

The main objective of this research is non-linear modeling of growth curve during kefir grains batch propagation. For this purpose some laboratory experiments were performed in an RC1 reactor provided data for growth curve construction. Afterwards, we fitted several growth models (Logistic, Gompertz and Richards) and compared their biological parameters. Finally, we established the statisticall...

the performance of a plug flow electrocoagulation reactor for the treatment of cattle abattoir(slaughterhouse) wastewater was investigated. a cylindrical iron reactor was operated as a cathode at arecycling batch mode while three iron rods located at the center of the reactor were used as an anode. theeffects of different parameters, including the current density, the supporting electrolyte dos...

background: among alkanes, n-alkanes with medium chain have been identified as the most important contaminants of the soil. n-hexadecane (c16h34) with low solubility in water also belongs to this group and has been used by many researchers as a model contaminant. the present study aimed to investigate the effect of the external source of carbon (glucose) as co-substrate on removal of hexadecane...
