BIOFUEL

This document discusses biofuels as alternatives to fossil fuels. It defines biofuels as hydrocarbon fuels produced from organic matter over days to months. Biofuels are necessary because fossil fuels are finite and prices will rise as availability decreases. Benefits of biofuels include similar energy content to petroleum fuels but with fewer emissions and pollution. Common biomasses used for biofuel production include soybeans, corn, sugarcane, and agricultural wastes. The conclusion advocates for biofuels as clean-burning alternatives that can be blended with diesel fuel without engine modifications.

BIOFUELS FROM BIOMASS PRESENT  Introduction to biofuels.  Necessity of biofuels.  Advantages of biofuels over fossil fuels.  Production of biofuels from biomass.
INTRODUCTION TO BIOFUELS • Biofuels are fossil fuel substitutes that can be made from a range of agricultural crops and other sources of biomass. • It is a hydrocarbon fuel that is produced from organic• It is a hydrocarbon fuel that is produced from organic matter in a time interval of days, weeks or even months. • Biofuels are considered as an alternative source of energy • In 1890s Rudolf Diesel was the first person who made biofuel from vegetable oil.
Necessity of biofuels Since the Fossil fuels are not renewable, it means that these fuels will run out off stock at some point and our ability to extract fossil fuels from the ground will diminish, hence the available supply will decrease resulting in huge increment inavailable supply will decrease resulting in huge increment in prices of fuels and may lead to inavailability of fuels to future generations. So, Biofuels can be looked upon as a way of energy security which stands as an alternative of fossil fuels that are limited in availability. Today, the use of biofuels has expanded throughout the globe.
Advantages of biofuels over fossil fuels • The energy content of biofuels is about 90% that of petroleum fuels. • Biofuels burn cleaner than fossil fuels, resulting in fewer emissions of greenhouse gases, particulate emissions.emissions. • Biodiesel is sulfur free. • Biodiesel has fewer cancer causing polycyclic aromatic hydrocarbons. • Additionally, biofuels are biodegradable, so if they do spill, less harm is done compared to when fossil fuels spill.

BIOFUEL
CONCLUSION  Biofuels are eco-friendly, clean burning alternative fuels.  Biofuels such as biodiesel contain no petroleum, but can be blended with conventional diesel fuel and can be used in any diesel engine without any modification. A successful example to acceptance of biofuels :A successful example to acceptance of biofuels :  First successful trial run of a superfast train Delhi-Amritsar Shatabdi Express was conducted on Dec 31, 2009 using 5% biodiesel and 95% petroleum diesel.  Railway annual fuel bill = Rs 3400 crores (for Diesel)  10% mixture with Diesel = reduced (Rs.300-400 crores / annum)
