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........i have applied material as well as energy balance on the reactor.........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
