Direct Liquefaction and hybrid processing
1. What is the distinguishing operational environment of direct liquefaction and what dictates this condition?
2. Delineate the four operational regimes of hydrothermal processing and indicate differences in the products resulting.
3. Why is water key to direct liquefaction even when other solvents are employed?
4. Describe syngas fermentation as a hybrid processing system and indicate its advantages and disadvantages.
5. Describe bio-oil fermentation as a hybrid processing system and indicate its advantages and disadvantages.
An air standard Diesel cycle has a compression ratio of 15, and the heat transferred to the working fluid per cycle is 800 Btu/lbm. At the beginning of the compression process the pressure is 14.7 lb/in^2 and the temperature is 60 F. Determine the pr..
