Errata: “Modeling of Trickle Bed Reactors Involving Beds of Different Configurations under Low and High Interaction Regimes”. M. M. Awad* Volume 46, No. 3, pp 677-683 For this article, the following errata are requested. Since f is proportional to Re-0.2 for the high interaction regime and f is proportional to Re-1 for the low interaction regime and based on the negative values of b in eq 7, eq 6 must be f ) cReb Equation 9 must be

X)




Rm

fφ) j (5+b)φ2 δ




Rm j (5+b) X2δ

Equation 10 must be

φ)




Rm j4 X2 δ

for the low interaction regime

Equation 11 must be

φ)




Rm j 4.8 X2δ

for the high interaction regime

i.e. under the square root in eqs 9-11, the power of X must be 2 not 1. IE900577B 10.1021/ie900577b Published on Web 04/21/2009
