| Starting with this equation: |
(1)
|
|
we begin by multiplying the top and bottom of the
left-hand side of
equation (1) by the same combination of constants (which is
equivalent to multiplying equation (1) by one):
|
|
Since the product of
is constant, we can take it inside the derivative in the denominator
to combine it with our length (z):
|
|
|
We'll convert from reactor length (z) as our dimension
to catalyst weight (W) by making use of the equation for catalyst
weight:
|
 |
| where: |
|
| Then: |
|
| With a little rearranging: |
|
| which we substitute into equation (1) to get: |
