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...
On the effect of a diffusing catalyst on the rate of absorption with a catalytic chemical reactionThe 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 ...

Catalyst, in chemistry, any substance that increases the rate of a reaction without itself being consumed. Enzymes are naturally occurring catalysts responsible for many essential biochemical reactions. In general, catalytic action is a chemical reaction
Relationship of conversion to catalyst contents was studied for three different material catalytic reaction systems with continuous -flow of reactants as follows:(1) MoVTeNbO/SiO_2 catalysts for selective oxidation of propane to acrolein;(2) KMoNi/SiO_2 catalysts for methanethiol synthesis from high...

This effect, termed non-faradaic electrochemical modification of catalytic activity (NEMCA), leads to a steady-state catalytic reaction rate increase up to 3 × 10times higher than the rate of supply or removal of Oat the catalyst surface. Here we report that β"-AlO, which is a Na...
Although you can configure subsecond PIM query intervals on Catalyst 4500 platforms, such an action represents a compromise between convergence (reaction time) and a number of other factors (number of mroutes, base line of CPU utilization, CPU speed, processing overhead per 1 m-route, etc.)....
