A. The catalyst was not in its active form, for example, it needed to be pre - treated but was not. B. The amount of catalyst used was too large, causing it to have a negative effect on the reaction rate. C. The reaction rate was measured inaccurately, and the actual reaction rate...

The model of steady state diffusion and reaction in a catalyst pellet where a single reaction takes place is analyzed with the scope to predict effectiveness factor through a very simple and practical procedure. Non-linear usual reaction kinetics are used to investigate the agreement among exact or...

A theoretical analysis is presented to describe the rate data in terms of fundamental reaction steps involved in the overall methanation kinetics. A model involving reaction inhibition (by adsorbed CO) was used in combination with the physical properties of the catalysts to determine the ranges of ...

The direct synthesis of hydrogen peroxide from H2and O2has been studied using a high activity AuPd/TiO2catalyst. In particular, the effect of variation in the reaction conditions on the productivity of hydrogen peroxide formation is investigated in detail. The effect of H2/O2molar ratio, temperatur...
The dehydrogenation of isoamylenes on a membrane catalyst composed of a Pd catalyst with 5.9% Ni under nongradient conditions is inhibited by isoprene, while the reaction rate passes through a maximum when the partial pressure of hydrogen in the starting mixture is increased....
of the reactor performance at typical Claus plant-operating conditions was possible using experimentally obtained rate functions for the two simultaneous hydrolysis reactions and the H2S/SO2 reaction. Using these rate constants, rather small values of the effectiveness factor were predicted for the ...
