Distinguishing different regimes for slurry systems

In this transport-limited region, the conversion increases at a slower rate than the increase of amoimt of catalyst, and thereby, the overall rate decreases instead of remaining constant as in the kinetic regime. In other words, in this region conversion is influenced by different factors (a) the additional catalyst surface area provided does not come in full contact with the pollutant due to external mass transfer resistance, and/or 

The agglomerate size is in close agreement with data obtained independently and reported elsewhere (Hoffmann et al., 1995) compared to average primary particle size of Degussa P25 as 30 nm.
