you can use the packed bed reactor and change the catalyst type and loading

What you need to do is keep all the conditions of the reaction constant and vary only one condition for different catalyst acting on the jatropha circus seed. For example you can keep temperature, pressure constant and vary concentration of different catalyst acting on different specified amount of the jatropha circus seed and the measure the amount of biodiesel produce per different catalyst concentration. The data obtain from catalyst concentration (serve as input); and that obtain from biodiesel produce per specified amount of catalyst (serve as output). Then the model will be obtain from input and output obtain in this regard. Thereafter, The simulation will follow. Thereby, proceeding to analysis and conclusion.

The information available about the biodiesel production from jatropha is huge. you could find information in ScienceDirect or Google, but first, you need to establish what kind of reactor do you want to model Second you need to choose the most important catalysts for your process and finally do the references search. Try to find kinetics studies, a lot of times this information is enough for the reactor modeling. I send you a couple of papers about the topic, but please find more information in the databases.

Good luck and best regards,
