Kinetic investigations and model-based optimization of CuO/ZnO/ZrO 2 : H-FER 20 catalytic systems for direct DME synthesis from CO -rich syngas.

A mathematical model for commercial naphtha catalytic reformer of Tehran refinery was developed. This model includes three sequencing fixed beds of Pt/Al2O3 catalyst at the steady state condition using detailed kinetic scheme involving 26 pseudo-components connected by a network of 47 reactions, in the range of C6 to C9 hydrocarbons. The reaction network consisted dehy...

A rhodium carbonylation catalyst is supported on dispersible microporous polymer nanoparticles, facilitating in situ kinetic measurements for a key step of the catalytic cycle.

This study describes a new simple, sensitive and selective catalytic kinetic spectrophotometricmethod for the determination of vanadium (V). The method is based upon the catalytic effect ofvanadium (V) on the oxidation of Carminic acid by bromate in sulfuric acid media. The reaction wasfollowed spectrophotometrically by measuring the decrease in absorbance at 490 nm and thedependence of sensiti...
