The extraction of Bio-ethanol from banana and apple peelings through the process of Fermentation and Distillation Purpose & Hypothesis The main purpose of the experiment was to observe if the common household wastes apple and banana peelings- were suitable to be used as another source for production of bio-ethanol It was hypothesized that the banana peelings would produce more bio-ethanol than the apple peelings due to its greater amount of sugar Ethanol‚ which is also known as ethyl alcohol

People who have to drive to work long distances‚ people who don’t have the money to buy more fuel-efficient cars right now and they’ve seen their standard of living drop substantially as a consequence of higher gas prices. Now‚ the only thing as predictable as rising gas prices are the short-term political solutions that usually come along with

Finding Alternative energy sources is a significant issue from all over the world. In contemporary society‚ due to the lack of fossil fuels and environmental problems like air pollution‚ alternative sources of energy have being utilized widely for different domestic and industrial applications. Biogas is one of the alternative energy which instead of fossil fuels. This essay will focus on how to harness biogas effectively and it will highlight biogas as an important alternative energy plays an important

Plan: Aim: The enthalpy change of combustion of a fuel is a measure of the energy transferred when one mole of fuel burns completely. A value for the enthalpy change can be obtained by using the burning fuel to heat water and using fact that 4.2j of energy are required to raise the temperature of 1g of water by 1oC. In this investigation my aim is to find the enthalpy change of combustion of a number of alcohols so that I can investigate how and why the enthalpy change is affected by the molecular

Core 1 summary notes 1) Fossils fuels provide both energy & raw materials such as ethylene‚ for production of other substances Identify the industrial source of ethylene from the cracking of some of the fractions from the refining of petroleum Catalytic cracking is the process whereby high molecular weight fractions are broken down to low molecular weight ones. This process is used in petroleum refineries where crude oil is broken down to smaller alkenes and alkanes‚ until ethene‚ propene‚

imposed on the environment by these fuels‚ biofuels were created. By dissecting the word‚ its meaning can be discovered. With the prefix “bio-“ meaning life‚ biofuel means just that‚ fuels derived from living subjects. With consumer demand reaching all-time high levels‚ the creation of biofuels was completely necessary to help diminish certain issues‚ but on the other hand‚ the use of biofuels does possess some flaws. Today there are two main forms of biofuels: ethanol for vehicles running on gas engines

test batches with new oil that pass the quality control checks provided‚ you’ll learn how to make test batches with used oil (WVO) that also pass the quality checks. Then you’ll be ready to move up to production of full-sized batches of top-quality fuel. Get some methanol‚ some lye and some new oil at the supermarket and go ahead -- it’s a real thrill!

Biodiesel are basically a fuel that is used as an alternative fuel. This is made using renewable resources like vegetable oil and animal fats.

This is the reasons why the researchers decided to make biodiesel
