Catalyst Modeling - Sizing and Selection

Careful consideration of the catalyst size means the customer can get the most cost effective solution possible, without overpaying for unneeded catalyst. That is why DCL has developed a detailed database of catalyst performance and conversion efficiencies. Catalyst conversion efficiencies are shown below for carbon monoxide in a variety of real-world operating conditions. Conversion efficiencies are charted in a generalized form, establishing a correlation between the Sherwood (Sh), Reynolds (Re) and Schmidt (Sc) numbers.

DCL uses in-house steady state and transient catalyst models, including chemical kinetics, mass transfer and back-pressure sub-models, for assisting with application engineering and catalyst design. Statistical methods are used to manage risk so that an optimum catalyst size can be established.
