Cassava as ethanol
Chapter I

Introduction

The cassava (Manihot Utilissima), that is extensively cultivated as an annual crop for its edible starchy tuberous root, a major source of carbohydrates. The cassava root is long and tapered, with a firm homogeneous flesh encased in a detachable rind. In experiments, cassava yielded two to three times as much carbohydrate for fuel ethanol production (Comis, 2008).
Ethanol production from fresh cassava roots using a low-temperature process was evaluated on a pilot-plant scale. The application of low-temperature cooking to cassava starch followed by a dual enzyme action resulted in an ethanol yield comparable to that of a traditional high-temperature cooking process. Pressurized distillation gave a satisfactory recovery efficiency of ethanol but was slightly lower than that obtained from atmospheric pressure distillation. Over 40% of the normal steam consumption was saved by adopting the low-temperature cooking and pressurized distillation systems in the cassava-to-ethanol process. The yield of anhydrous ethanol varied with the starch content in fresh cassava roots and was in the range of 185 to 200 litres per tonne (Atthasampunna et.al, 2009).
As strengthen by Guindo, 2013, the world has evolved into a place where convenience is taken as a one of the major reasons why technology is at its peak in its continuous and countless innovations. These innovations are true manifestations that there is no room for being stationary and not disregard the need for continuous brilliant discoveries in order to offer fresh and up to date products and services that will be patronized by the consumers. Amidst this fascinating waves of new products and services to offer, a discovery that has been the most important source of these vivid ideas, has never been given much attention and is abused to its extent. This amazing discovery is what we call Electricity.
In today's culture, electricity is a vital part of functioning as a society. Simple tasks, such as

    The first use of electricity by the human race was recorded back to 600 BC when Thales of Miletus wrote about the charging of amber on rubbing it, that is what we know as static electricity. But the most important contribution to electricity was from Nikola Tesla, a mechanical and electrical engineer and inventor he developed commercial electricity. Think of the countless luxuries that are afforded to us by energy workers that we take for granted. Imagine if they were all gone we would all be forced to resort to old methods of getting things done, and stop doing some things all together. Almost all Americans use electricity, and if we did not have it we would be anywhere close to where we are today. Not just America either, economies around the world are completely reliant on electricity.…

    Instead of growing corn based ethanol, which causes negative effects to our economy and to the environment, researchers have discovered a new product, "cellulosic ethanol." Cellulosic ethanol is formed from waste plant material (cellulose) through a process called “thermo-chemical conversion”. Cellulosic ethanol plants are underway and the future of ethanol energy is making huge advancements. Unlike corn based ethanol, cellulosic ethanol will be less harmful to the environment and more economically…

    First of all, the author asserts that the ethanol fuel would not assist to fix global warming problem. Conversely, the lecturer brings up the idea that augmented of ethanol fuel does not adversely affect the environment. In other words, cultivating plants to produce ethanol fuel not only would not ascend the greenhouse gases but also simply compensate disadvantages of burning such gasoline fuel effects on the atmosphere.…

    Ethanol is made by mixing yeast with plant material and kept warm. Yeast is a unicellular organism whose diet is made of plant material. Sugars are turned into alcohol by the yeast. This process, used in producing ethanol, is called fermentation. Primarily corn is used to produce ethanol in the United States. Ethanol creates less polluting gases than gasoline or diesel. Mixing gasoline and ethanol can help decrease pollution. Brazil is the world’s largest ethanol producer (Solway 12). Ethanol is produced from sugarcane in Brazil. The sugarcane is crushed to extract the sugar. Then the sugar is dissolved. Vehicles in Brazil run on a higher concentration of ethanol than vehicles in the United States. The remnants of the sugarcane is referred to as bagasse. Dried bagasse can also be used as fuel (Solway 13). Power plants may burn bagasse to produce electricity. Sugarcane can produce the power needed to keep the ethanol plant running and the sugar to make ethanol.…

    Ethanol, a Fuel

    • 548 Words

    Ethanol fuel is a type of alcohol found in alcoholic beverages that is often made from common agricultural products. It is either mass-produced by fermentation of sugars or from cellulose. Wheat or corn kernels are ground in a hammer-mill to expose the starch, the ground grain is then mixed with water, heated briefly and enzymes are added to convert the starch to sugar using a chemical reaction called hydrolysis. Yeast is added to ferment the sugars to ethanol and finally the ethanol is separated from the mixture by distillation. The fermentation process is quite simple; a glucose molecule is broken down into ethanol molecules and one carbon dioxide molecule, the carbon dioxide is released into the air and you are left with a colourless, clean burning liquid with a strong odour. This makes it easy to produce an alternate cleaner burning fuel for cars and other means of transportation. Ethanol is already being used in high-performance motor fuel because it cuts poisonous emissions and is better for the environment then traditional fuels. There have been many developments in using a higher ethanol concentration in fuels for cars and other types of transportation, by many leading car companies research institutes. New engines have been developed called Flexifuel, these engines are able to burn a E85 fuel opposed to the traditional motor fuel with an ethanol concentration at most of 10%, this makes the E85 fuel less expensive and cleaner burning. The Canadian government and some provinces have continuously supported the product of ethanol fuel and the use of it, any ethanol blended fuel receives exemption from the federal tax of 10 cents a litre for gasoline. As reaction to the Government of Canada Action Plan 2000 on Climate Change, the government of Canada establish the Future Fuels initiative to increase the supply and use of ethanol produced from biomass. There is three main components to this initiative that the Canadian Government has…

    As we come into high school, we continue to learn more and more of our great nation’s history. Countless events had led up to what the world is today, such as the civil rights movement, women’s right to vote, 9/11, and Pearl Harbor. Although, there are more influential events on our world. To be specific, Benjamin Franklin. Benjamin Franklin gave us one of the greatest gifts the world has ever received, electricity. “People always fear change. People feared electricity when it was invented, didn't they? People feared coal, they feared gas-powered engines... There will always be ignorance, and ignorance leads to fear. But with time, people will come to accept their silicon masters.” (Bill Gates). The gift of electricity has impacted our nation in several ways, but the main key factors as to why its important is communication, entertainment, and business.…

    This lesson started by stating the importance and multiple uses that we give electricity. This is the main (and only as far as I can tell) source of energy that our electrical devices need to work and give us all of the amenities that we have come to get used to. From electric lighting to TVs and microwaves, electrical appliances and electronic devices make us rely heavily on electricity. Electricity makes the alarm clock go off in the morning and provides us artificial light at night when there's no more day light. There are one hundred and one reasons to love how we manipulate electricity to power our electric devices, however, we have only a few ways that we can generate it. As any other form of energy, we are limited in its quantity. This has urged us to redesign our appliances and other electric devices to conserve it. From different types of electric lighting to efficient major appliances, our lesson talks about the efficiency factor in them and what the best choices are depending on this factor. Formulas were provided to calculate energy costs (in this case electricity) and determine efficiency.…
