ALCOHOL AS AN ALTERNATIVE FUEL IN I.C ENGINES Presentation Transcript:
1.ALCOHOL AS AN ALTERNATIVE FUEL IN I.C ENGINES
2.INTRODUCTION
In this century, it is believed that crude oil and petroleum products will become very scarce and costly.
Day-to-day, fuel economy of engines is getting improved and will continue to improve. However, enormous increase in number of vehicles has started dictating the demand for fuel.
With increased use and depletion of fossil fuels, alternative fuel technology will become more common in the coming decades.
Because of the high cost of petroleum products, energy security , emission problems some developing countries are trying to use alternate fuels for their vehicles.
3.LIQUID FUELS
Liquid fuels are preferred for IC engines because they are easy to store and have reasonably good calorific value. The main alternative is the alcohol
ALCOHOL
Alcohols are attractive alternate fuels because they can be obtained from both natural and manufactured sources. Methanol and ethanol are two kinds of alcohols that seem most promising.
4.What about Using Ethanol and/or Biodiesel for Fuel?
5.Structure of ethanol molecule.
6.Ethanol
HOW IS IT MADE NOW?
HISTORICALLY MADE FROM CORN AND OTHER STARCH SOURCES OR FROM NATURAL SUGARS BY FERMENTATION
COMMON SOURCES INCLUDE RICE, POTATO, CASSAVA – PLUS CORN AND OTHER GRAINS
MANUFACTURING PROCESS WAS VERY ENERGY-INTENSIVE, BUT IS NOW LESS SO IN MOST MODERN PLANTS, DUE TO ADVANCES IN DISTILLATION TECHNOLOGY
7.Ethanol
8.Michael Wang – Argonne National Laboratory, Aug. 2005
9.Some Properties of Methanol, Gasoline and Diesel Fuel
10.BIOMASS TO ETHANOL
AN INTEGRATED, FULL-SCALE COMMERCIAL BIOPROCESS PLANT CONSISTS OF FIVE BASIC UNIT OPERATIONS
1. FEEDSTOCK PREPARATION;
2. DECRYSTALLIZATION/HYDROLYSIS REACTION VESSEL;
3. SOLIDS/LIQUID FILTRATION;
4. SEPARATION OF THE ACID AND SUGARS;
5. FERMENTATION OF THE SUGARS; AND,
6. PRODUCT PURIFICATION.
