‘Radial and axial dispersion related to dilution in fixed-bed laboratory reactors’
There are three papers containing the results of an investigation of the effect of inert bed dilution on the conversion in gas-solid fixed beds, which was carried out in Delft. This work was carried out within Eurokin since it was concluded earlier that the often-used equation from Van den Bleek to estimate the maximum allowed amount of inert bed dilution in a gas-solid (or liquid-solid) fixed bed reactor is not reliable and not generally applicable. The effect of dilution on the conversion was investigated by simulations and experiments in the six-flow reactor in the laboratory.
The work published in the three papers below was also presented at the Reactor Engineering session of the Europacat V conference (2-7 September 2001, Limerick, Ireland) and also at the conference NCCC III (the Netherlands’ Catalysis and Chemistry Conference 2002, 4-6 March 2002, Noordwijkerhout).
The Second dilution paper was published in February 2002 in Aplied Catalysis A: General: R.J. Berger, J. Pérez- Ramírez, F. Kapteijn, J.A. Moulijn, Catalyst performance testing: Radial and axial dispersion related to dilution in fixed-bed laboratory reactors, Applied Catalysis A: General 227 (2002) 321-333.
This paper concerns the influence of different macrodistributions of catalyst and inert bed dilution. From the results the bed tortuosity was estimated.
