Chapter 5: Isothermal Reactor Design: Conversion
Converting from Length (z) to Catalyst Weight (W):
| 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: |
