Chapter 15, Problem 15.3P

(a)

Interpretation Introduction

Interpretation:

The regions that correspond to the external mass transfer limited in the given graph are to be stated.

Concept introduction:

The full form of PBR is Packed-Bed Reactor which is used for the fluid-solid heterogeneous reactions. These fluid-solid heterogeneous reactions take place at the surface of the catalyst.

(b)

Interpretation Introduction

Interpretation:

The regions that correspond to the reaction rate-limited regions in the given graph are to be stated.

Concept introduction:

The full form of PBR is Packed-Bed Reactor which is used for the fluid-solid heterogeneous reactions. These fluid-solid heterogeneous reactions take place at the surface of the catalyst.

(c)

Interpretation Introduction

Interpretation:

The regions that correspond to the internal diffusion controlled regions in the given graph are to be stated.

Concept introduction:

The full form of PBR is Packed-Bed Reactor which is used for the fluid-solid heterogeneous reactions. These fluid-solid heterogeneous reactions take place at the surface of the catalyst.

(d)

Interpretation Introduction

Interpretation:

The internal effectiveness factor at $400\text{K}$ and $d_{\text{p}}=0.8\text{cm}$ is to be stated.

Concept introduction:

The full form of PBR is Packed-Bed Reactor which is used for the fluid-solid heterogeneous reactions. These fluid-solid heterogeneous reactions take place at the surface of the catalyst.
