Fossil Fuels: Types and Use Outline Origins and Types Exploration and Development Production Use The Environment Photosynthesis Radiant
energy Chlorophyll, turning sunlight into carbohydrates. Combines radiant energy, CO2 and H2O, and produces O2 and carbohydrates. Carbon and Oxygen cycles. Fossil Fuel Origins
The organic (carbon-based) remnants of ancient life. Anaerobic bacteria: Bacteria that thrive where there is NO Oxygen broke down the remains into molecules of hydrocarbons of various sizes. Overburden: Pressure and heat from the sediment and rock above the deposits helped the process of refining the material into fuel. Coal There
are various types of coal that reflect the long process by which it is made. Peat compressed dead leaves in bogs. Lignite dirty, brown coal, can still see bits of leaves. Bituminous and Sub-bituminous. Anthracite the oldest, hardest, cleanest coal. Carbon-based fuels
Hydrocarbons: molecules of carbon and hydrogen, mostly carbon. Anthracite is nearly 90% carbon atoms Lignite, less than 50%. Natural Gas, made of methane (CH4), has a relatively low carbon content. A clean burn of such fuels produces CO2 and H2O (Carbon dioxide and water). Contributes to the Greenhouse effect. Trace Elements in Fossil fuels
Carbon and hydrogen arent alone. Coal and oil contain up to 2% Sulfur. Produces Sulfur dioxide, SO2, upon burning, leading to acid rain. Other non-combustible materials producing ash or soot particulates. Coal even has uranium in it, the stuff of atom
bombs. Presently, more radioactive materials are introduced into the environment by the burning of coal than by nuclear power production. Fossil fuel deposits Coal lies in great beds usually just under the surface. Oil and Natural Gas are typically found where the rock above has formed a natural cap, or dome. Geologic entrapment.
Fossil Fuel Exploration and Recovery Use Seismic data to map the underground looking for domes of rock that might hold oil and gas. Drilling Exploratory wells -- 1 in 9 is successful in US. Primary recovery natural pressure 15% of deposit. Secondary recovery pump water or gas to force oil out 15% more. Tertiary recovery techniques to reduce viscosity
and surface tension 10% Methods of Further Refining Coal can be further processed to obtain synthetic liquid or gas fuels. Natural Gas can be
compressed into a liquid. Oil is refined into numerous different products. Cooling and Condensing As it rises Gasoline Additives Lead enhances octane rating.
MTBE an oxygenate to reduce Carbon monoxide emissions now suspected of being a carcinogen. Ethanol corn or sugar cane turned into alcohol to improve octane, make the fuel cleaner, make the farmers happy. Natural Gas the next big thing.
Natural gas burns cleaner. Less carbon per weight. New turbine designs use the natural gas to run a turbine, and then heat up water to run a traditional steam generator Efficiencies of 45% or more. Natural gas is cheaper 3.5 to 1 compared to coal, 1.75 to 1 compared to gasoline. Outlook Still the easiest and cheapest fuel around.
Technologies are being developed to increase yields, enhance efficiency and reduce pollution. The biggest obstacles remain that they are non-renewable, carbon-based resources.

Background. Radiation is made up of certain particles that are so highly energized that they transfer energy through ionization. All the matter around this radioactive particle either loses or gains electrons creating fast moving particles and waves.
