Fructose may be produced catalytically from glucose using immobilized glucose isomerase as the catalyst.

If 100 mol/hr of fresh feed containing 35 mole% of glucose in water was used in the catalytic process, and that the gross feed to the reactor contains 6.75% fructose, what is the amount of fructose (in moles) in the recycle stream? Assume the ratio of the exit stream to the recycle stream in mass units is equal to 8.46.
