Analysis of Biomass and Biofuels as source of energy With your favorite host Bikramjeet Singh B.Tech(hons)IT_MBA(intg) www.powerpointpresentationon.blogspot.com
Technology Biomass technology today serves many markets that were developed with fossil fuels and modestly reduces their use Uses - Industrial process heat and steam, Electrical power generation, Transportation fuels (ethanol and biodiesel) and other products. Primary focus of the Biomass Program – development of advanced technologies.
Current Focus Platform technologies Sugar Platform Technology Thermochemical Platform Technology
Bio-refinery A facility that integrates biomass conversion processes and equipment to produce fuels, power, and chemicals from biomass. Analogous to today's petroleum refineries It is based on the “Sugar Platform“ and the “Thermochemical Platform“
Bio-diesel Made by transforming animal fat or vegetable oil with alcohol . Fuel is made from rapeseed (canola) oil or soybean oil or recycled restaurant grease. Directly substituted for diesel either as neat fuel or as an oxygenate additive
Jatropha Biodiesel from Jatropha Seeds of the Jatropha nut is crushed and oil is extracted The oil is processed and refined to form bio-diesel.
Gasification Technology Gobar gas Production Biogas Synthesis gas
Gasification A process that uses heat, pressure, and steam to convert materials directly into a gas composed primarily of carbon monoxide and hydrogen. .
Gasification Products of gasification : * Hydrocarbon gases . * Hydrocarbon liquids (oils). * Char (carbon black and ash).
Gobar gas Gobar gas production is an anaerobic process Fermentation is carried out in an air tight, closed cylindrical concrete tank called a digester
Environmental Concerns • Air Pollution • Soil Deterioration
Air Concerns • Biomass processing technologies and biofuels use have the potential to increase emissions of ozone precursors • Increase in Nox emissions • Combustion of ethanol would result in increased atmospheric concentrations of carcinogens
Soil Concerns • Burning biomass deprives local eco-systems of nutrients • Increased use of pesticides and fertilizers to produce energy crops contaminate ground and surface water # Affects fish and wildlife
Environmental Benefits • Reduction of waste • Extremely low emission of greenhouse gases compared to fossil fuels • Ethanol is Carbon neutral and forms a part of the carbon cycle • Growing variety of crops increases bio-diversity
Bio Mass Biomass already supplies 14 % of the world’s primary energy consumption. On average, biomass produces 38 % of the primary energy in developing countries. Fertilizers as by product. Average electricity generation of 5.5kWh per cow per day!!
