APPROXIMATE EFFECTIVENESS FACTOR ESTIMATION FOR WAVE SHELL CATALYST

The estimation of effectiveness factor for the case of wave shell cata lyst is attempted through an approximated procedure developed by the a uthors for other kind of catalytic pellets. It is shown that the appro ximate scheme ran be used even with this kind of important catalysts a nd that the results so obtained are very accurate. The analysis is onl y restricted to the case of single reaction although it can be used ev en for those cases where non-isothermal conditions could prevail. The estimation avoid the solution of the governing mass and heat balance d ifferential equations by numerical procedures. Finally a set of algebr aic equations must be solved through an iterative scheme which is illu strated for the case of isothermal systems.
