I recently posted on this forum about 'Use Of Euler's Approach In Reaction Kinetics', and I attempted this. I had a meeting with my lecturer on Thursday and he found that the paper I used didn't have nice rate equations as the rate seemed to be inhibited by the products. I was given another catalyst and rate equation to use and found the rate of the reaction as well as the weight of catalyst. I am now attempting to find the pressure drop using the Ergun Equation. All I was told by my lecturer was to follow the paper that he sent to find the mean voidage and then use solver in Excel to find the appropriate pressure drop as we do not have a tube diameter or height of the bed (which I was told have to be in a relationship of H/D > 3). I'm having problems with finding the pressure drop within the 10% of global pressure (which I actually don't know what he means by global pressure and was wondering if he is talking about atmospheric pressure of the region), which I assume to mean 1 atm, however the dt/dpe relationship is always greater than 50 which is the maximum allowed.
I have attached the excel file and also the papers below but the excel file should have everything necessary.
Thanks
