ABSTRACT

This study proposes that mechanical pretreatment of the algae Ulva reticulata will increase the percentage of ethanol produced. Two batches of sample will be prepared. The first will serve as a control. The second will be subjected to maceration. The two batches will undergo dilute acid hydrolysis. The sugar released will then be fermented to produce ethanol. The ethanol yield of the two batches will then be compared. The result of the comparison will justify the effect of mechanical pretreatment on the bioethanol yield from Ulva reticulata.

I. INTRODUCTION

The growing demand in energy rapidly depletes the conventional sources of fuel such as coal and petroleum. These kinds of fuels are non-renewable because it takes million of years to form. This is one of the reasons why most of the researches are inclined to find alternative fuels which are renewable.

Biofuels are referred to solid, liquid or gaseous fuels derived from organic matter. One of the examples of renewable fuels is bioethanol. The sources of this type of fuel are classified into three: the first, the second, and the third generation [1].

First generation

    Bio-ethanol is manufactured from fermenting starch, wheat and sugar cane. Ethanol is also made from the hydration of ethylene from petroleum, though the majority of ethanol is produced by fermentation. It is considered an alternative fuel source as it is regarded to be renewable and more beneficial to the environment. As a car fuel ethanol is blended with petrol in different concentrations.…

    The environmental impacts of farming practices can also be reduced with the adoption of sustainable production methods in the agricultural sector. Growing corn, wheat, rice, and sugarcane produces large amounts of agricultural wastes, some of which are burned, degrading air quality. In the production of cellulosic ethanol, the bulk of the biomass would become a valuable source of energy rather than a waste product. In fact, municipal solid waste (MSW) includes a large volume of cellulosic material that has the potential to be converted to ethanol.…

    A biofuel is a source of energy that is made from living things or their products. Biobutanol, a four-carbon alcohol, is a type of biofuel. It has a higher energy than ethanol and can be used in vehicles without them needing modifications to their engines (1). Biobutanol is related to photosynthesis because the biobutanol can come from plants of biomass feedstocks, hence the name, biomass butanol (2). Biomass feedstocks are the plant matter that fuels are derived from. Biobutanol can be, in its first and simplest form, a plant that performs photosynthesis.…

    The percent yield of ethanol from sucrose was successfully high, at 93.3 %. The final mass of the distillate obtained after fermentation and the fractional distillation process was 0.81g. The distillate was collected when the temperature reached approximately 50-70°C. The amount of ethanol that should have been produced was 13.66 ml, had the entire distillate (over 100 ml) been distilled fractionally . The density of the distillate obtained was 0.81 g/mL; therefore, the percent ethanol by weight was approximately 90%. The distillate contained mostly ethanol, but also contained water because due to the azeotropic mixture water and ethanol mix to produce, consisting of 95% ethanol and 5% water by weight. This experiment was a success due to the high percent yield of ethanol from the fermentation of sugar.…

    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…

    he capture of solar energy through photosynthesis is a process that enables the storage of energy in the form of cell wall polymers (that is, cellulose, hemicellulose and lignin). The energy stored in these polymers can be accessed in a variety of ways, ranging from simple burning to complex bioconversion processes. The high energy content and portability of biologically derived fuels, and their significant compatibility with existing petroleum-based transportation infrastructure, helps to explain their attractiveness as a fuel source. Despite the increasing use of biofuels such as biodiesel and sugar- or starch-based ethanol, evidence suggests that transportation fuels based on lignocellulosic biomass represent the most scalable alternative fuel source1. Lignocellulosic biomass in the form of plant materials (for example, grasses, wood and crop residues) offers the possibility of a renewable, geographically distributed and relatively greenhouse-gas-favourable source of sugars that can be converted to ethanol and other liquid fuels. Calculations of the productivity of lignocellulosic feedstocks, in part based on their ability to grow on marginal agricultural land, indicates that they can probably have a large impact on transportation needs without significantly compromising the land needed for food crop production2.…

    A biofuel is any fuel that is made from plant material. Many biofuels can replace diesel or gasoline in today’s modern cars. One of the most common biofuels is wood. Biofuels can store energy just like any other fuel. Biofuels are also an example of a renewable resource.The best way to reduce global warming is to decrease fossil fuel usage. One way to do that is to substitute biofuels in the place of fossil fuels.…

    Biodiesel production yields varied from 81.7 to 88.0 (wt%), the lowest yields being the ones obtained using waste frying oil and lard alone as raw materials. The obtained products fulfilled most of the determined quality specifications according to European biodiesel quality standard EN 14214. Minimum purity (96.5 wt%) was closely obtained when waste frying oil was used alone and when 0.2% of lard was incorporated in the raw material (96.3 wt%); however, it ranged from 93.9 to 96.3 (wt%) being always close to the limit. From the evaluation of the influence of mixture composition in biodiesel quality, it was possible to establish a model to be used for predicting some parameters of biodiesel resulting from mixtures of waste frying oil with lard when different lard contents are used. IODIESEL consists of a mixture of fatty acid alkyl esters, that can be used as an alternative fuel in compression-ignition engines; it is obtained from renewable resources, such as vegetable oils and animal fats, which makes it biodegradable and non-toxic [1],[2].…
