The reaction conditions adopted in this example are:
Pressure 40 bar
Temperature from 160 C to 260 C
Inlet H2/MAN molar ratio 40
H2 space velocity 2000 hr-1
In the above conditions the average performances of the reaction have been measured as follows:
Conversion: over 99 %
Selectivity to GBL: 93.40
Selectivity to THF: 4.8%
The overall material balance of the hydrogenation results as follows:
Entering
Organic feed 9700 Kg/hr
Hydrogen 140 Kg/hr
Total 9840 Kg/hr
Products and by products
GBL 2520 Kg/hr
THF 110 Kg/hr
GBL recycled to MAN absorber 6352 Kg/hr
Water 770 Kg/hr
By products 78 Kg/hr
Hydrogen purge 10 Kg/hr
Total 9840 Kg/hr
Look at the amounts, BIG!
Organic Synthesis Collective gives synthesis of THF from corn kernels, much more easy.
Very good presentation!!! To help SWIM thinks you post descriptions of n-butane oxidation so others can help you more.
