Heterogeneous Catalysis
Catalysis is a term coined by Baron J. J. Berzelius in 1835 to describe the property of substances that facilitate chemical reactions without being consumed in them. A broad definition…
Kinetics of Elementary Steps: Adsorption, Desorption, and Surface Reaction
The necessary first step in a heterogeneous catalytic reaction involves activation of a reactant molecule by adsorption onto a catalyst surface. The activation step implies that a fairly strong chemical…
Relaxation Methods
In the previous section the steady-state approximation was defined and illustrated. It was shown that this approximation is valid after a certain relaxation time that is a characteristic of the…
Process Description and Equipment List
AFTER THE process route has been selected, it is both possible and necessary to prepare an equipment list or equipment schedule. The process description, preliminary design calculations and equipment listing…
Heat Transfer: Radiation
So we’ve learned that conduction moves heat easiest through solids, and convection moves heat through liquids and gases. So how does the heat from the Sun get to Earth? There…
