Catalyst Geometrical Properties Calculator is a chemical engineering program to perform detailed characterisation of solid catalyst particle from various shapes (tablets, rings, ribrings, spokewheels and gatling guns shapes).
The program request the input of various geometrical parameters (outer diameter, central hole diameter, cylinder height etc...) and provide numerous geometrical calculation results (perimeter, surfaces, void fraction etc...) that enable the chemical engineer to characterise the effectiveness and/or the pressure drop properties of the proposed shape and dimensions.
The calculation take also account of the possibility to have flat or domed ends for each shape.
The program output also a scaled drawing of the proposed shape/dimensions to allow for example a visual check of the manufacturing feasibility of the proposed shape.
