Definition Of Yield

Question 1

What is the definition of yield

Answer 1

Kg of carbon black / kg of primary feedstock

Question 2

What factors affect yield?

Answer 2

Factors affecting yield can be divided into 3 categories. Energy source, critical equivalence, surface area

1. Energy source
   - Air and FS PH
   - FS (Coal tar is best)
2. Phi C (critical equivalence)
   - PC
   - lower hydrogen in FS
3. Surface area
   - mixing rate of FS in burner fire
   - recirculation in reactor
   - concentration effect
