Whаt is micrоаlgаe? List fоur advantages оf using algae as feedstock for producing biofuels instead of terrestrial biomass. What are the two major benefits of cultivating algae in saline water instead of freshwater? Microalgae can be cultivated either in open systems or closed systems. List three advantages of closed systems for microalgae cultivation and what is its major disadvantage? Explain the major technical challenge affecting the economics of commercial algae-based biofuels and bioproducts?
A 100 milliоn gаllоn аnnuаl capacity ethanоl plant is being planned. Ethanol (C2H5OH) is to be produced from locally grown switchgrass using a lignocellulosic fermentation technology (biochemical platform). Switchgrass is harvested once annually, contains 30% moisture and crop yield (includes moisture at harvest) is 14,000 kg/hectare. Average organic composition of switchgrass on dry basis is as follows: Cellulose (C6H10O5) = 45%; Hemicellulose (CH1.6O0.8) = 15%; Lignin= 15%; Ash= 8%; Extractives= 17%. Write balanced stoichiometries for the microbial conversion of cellulose and hemicellulose to ethanol. Using the above stoichiometries, calculate the ethanol yield from cellulose and hemicellulose in g/g. What is the yield of ethanol from switchgrass as harvested? Express this yield in L per metric tonne. How much switchgrass as harvested is required annually as feedstock for the plant? Assume 100% conversion of sugars and no losses during processing. Calculate the land area in hectares required to grow switchgrass that will meet the demand of the ethanol facility.
