Hi....... I am going to design a multi tubular fixed bed reactor for my final year project.....I have to design a reactor which produces 100 tons per day of dimethyl ether and my feed is 121 ton of methanol.....i have all the relevant kinetic data and catalyst properties............Now i want to calculate the weight of catalyst necessary to achieve 83 % conversion.....
I am Using the following equation to calculate the weight of catalyst:

Now the problem is that should i construct a levenspeil plot by calculating different reaction rates against different conversions and then calculating area under the curve by applying 1/3th simpson's rule as in Chapter 2 of Scott foggler book of reaction engineering
Or should i use the following method

I am getting a catalyst weight of 1620 kg by method 1 and a catalyst weight of 12630 kg by using method 2.........Please help me and tell me which catalyst weight is more realistic to process 121 tons of feed per day..........Regards
