    Control of the selectivity in partial oxidation of hydrocarbons (1999)
    Springer
    Reaction kinetics and catalysis letters 66 (1999), S. 47-54

    Thema: Chemie und Pharmazie
    Notizen: Abstract A simple kinetic model for the partial oxidation of hydrocarbons on two types of sites was used to study the factors influencing the selectivity to the desired product. It is possible to increase the selectivity significantly by regulating the ratio of the surface concentrations of partial and deep oxidation sites by a periodic temperature treatment.

    Multiplicity of regimes in a dual-reactor system for partial oxidation of hydrocarbons with the catalyst unsteady state (1999)
    Springer
    Reaction kinetics and catalysis letters 67 (1999), S. 213-218 
    Details
    ISSN: 1588-2837
    Schlagwort(e): Partial oxidation ; hydrocarbons ; catalyst circulation ; multiplicity

    Thema: Chemie und Pharmazie
    Notizen: Abstract A mathematical modeling of a dual-reactor system based on a simple kinetic scheme with two types of sites (accounting for deep and partial oxidation) has been performed. It has been shown that it is possible to regulate the state of a catalyst in the reaction zone by varying the rate of the catalyst circulation between the reactors, thus, significantly increasing the reaction selectivity. A region of multiplicity of the process stationary regimes has been found. This region appeared to become smaller with the increase of the catalyst circulation rate.

    Spatial regulation of the catalyst activity enhancement for catalytic reactions with stop-effect (1999)
    Springer
    Reaction kinetics and catalysis letters 68 (1999), S. 393-398 
    Details
    ISSN: 1588-2837
    Schlagwort(e): Dual-reactor system ; “stop-effect” ; catalyst circulation
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Chemie und Pharmazie
    Notizen: Abstract A kinetic model taking into account two types of active sites has been used for an analysis of factors influencing the rate of a catalytic reaction. It has been shown that the reaction rate can be significantly increased by performing the reaction with the “stop-effect” in a dual-reactor system due to the catalyst circulation between two reactors, one of which is purged with an inert gas.
