I need help with interpreting the kinetics of a scientific paper: https://www.researchgate.net/publication/284014208_Kinetic_modelling_of_methanol_conversion_to_light_olefins_process_over_Silicoaluminophosphate_SAPO-34_Catalyst
I am trying to reproduce the reactions in table 1 using a pfr in hysys. However, I am at a loss how to interpret the kinetics data given in table 3. The units given are in (mol gCatalyst−1 atm−1 h−1) which do not make much sense to me. I thought a 2nd order rate constant should have units of atm-1 h-1. Hence, I am unsure how to input the rate kinetics data.
Any help would be greatly appreciated.
