explore Question: Is algae a viable witness of qualification to corn ethanol as biofuel as an energy source for vehicle?
Introduction
* Microalgae are sunlight-driven cell factories that convert carbon dioxide to say-so biofuels, foods, feeds and superior-value bioactives.
* It contains lipids and red-hotty acids as membrane components, storage products, metabolites and sources of energy. Algal strains, diatoms, and cyanobacteria (categorized collectively as Micro-algae )have been found to contain proportionally high levels of lipids(over 30%)
* Ethanol production is a growing sedulousness in the United States, where corn is the feedstock used to produce more or less 90% of fuel ethanol. The average value of energy product/input ratio is 1.57 and 1.77 for the wet-milling and dry-grind ethanol processes, respectively.
The aim of the research is to distinguish whether algae or corn ethanol is a wear biofuel as an energy source for vehicle.
Chemical Concept
Theory fanny Production of Microalgae
In transestrification, triglycerides are reacted with methanol which is the least overpriced alcohol to produce methyl esters of fatty acids, that are biodiesel, and glycerol.
rear oil used in making biodiesel consists of triglycerides in which trey fatty acid molecules are esterified with a molecule of glycerol. It is catalyzed by acids, alkalis and lipase enzymes. Biodiesel is recovered by repeated washing with water to call for glycerol and methanol.

Structure and Composition of the Corn Ethanol
Corn kernels contain approximately 70% starch, 9% protein, 4% fat and oil, and 9% fiber on a dry basis. nigh corn grown for ethanol production is #2 scandalmongering dent corn. Energy is stored in the seed in the establish of starch and oil, which are segregated to the endosperm and germ,...If you want to get a full essay, order it on our website: Orderessay
