UCKRON II TEST PROBLEM THE EFFECTS OF PORE DIFFUSION |
| abstract |
The UCKRON I test problem was reworked with the inclusion of diffusional limitations to the kinetics. For this purpose, the rate expressions, i.e. the full kinetic model and the Langmuir-Hinshelwood model, proposed in the previous workshop, were assumed to represent the true kinetics.A simple mathematical model based on simplified effective diffusivities and the “Dusty-Gas” model were used to take account of pore diffusion resistance within the catalyst particle. These models predicted effectiveness factors based on the reaction at the bulk conditions. The effectiveness factors were then correlated against temperature and the partial pressure of reacting species.These correlations were then used to predict the temperature profiles within the water cooled plug flow reactor for various values of cooling media temperature. |

For this purpose, the rate expressions, i.e. the full kinetic model and the Langmuir-Hinshelwood model, proposed in the previous workshop, were assumed to represent the true kinetics.A simple mathematical model based on simplified effective diffusivities and the “Dusty-Gas” model were used to take account of pore diffusion resistance within the catalyst particle. These models predicted effectiveness factors based on the reaction at the bulk conditions. The effectiveness factors were then correlated against temperature and the partial pressure of reacting species.These correlations were then used to predict the temperature profiles within the water cooled plug flow reactor for various values of cooling media temperature.</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Turton, Richard</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">Chemical engineering communications</subfield><subfield code="d">London [u.a.] : Taylor & Francis, 1973</subfield><subfield code="g">76(1989), 1 vom: 01.
