  • Petroleum products are everywhere around us. They appear in visible forms, such as gasoline, diesel, kerosene, and aircraft fuels, and in less visible forms over the entire spectrum of industry, such as automobile lubricants, greases, carbon black for truck tires, bitumen for road building, the waterproofing in house roofs, feedstock for petrochemicals, synthetic fibers, and plastics. Petroleum feedstock is used in the manufacture of white mineral oils in eye ointment, hair oils, cosmetics, petroleum solvents, and pest control sprays....

  • When fuel cells were first suggested and discussed back in the nineteenth century, it was firmly hoped that distinctly higher efficiencies could be attained with them when converting the chemical energy of natural fuels to electric power. Now that the world supply of fossil fuels is seen to be finite, this hope turns into a need, into a question of maintaining advanced standards of life.

  • As in a past decades, the world today continues to be at crossroads in terms of energy. Shortages and rising prices of fuel, accompanied by environmental damage are leading to a poor quality of life. Fossil fuel consumption is increasing, and our search for oil has led to ever deeper reserves, with its higher production costs. Rapid depletion of oil and gas are real issues affecting both current and future generations.

  • Record-high world oil prices have prompted renewed interest in producing liquid fuels from coal. The United States leads the world in recoverable coal reserves. Moreover, the technology for converting coal to liquid fuels already exists, and production costs appear competitive at world oil prices well below current levels. Yet, despite

  • An active neutron method for measuring the inherent neutron emission of spent fuel assembly is proposed. The count rate of the inherent neutron emission can be determined by changing intensity of neutron irradiating source. The practical meaning of the method is presented. Some attractive features of the method are shown.

  • The most popular energy sources being used today (fossil fuels) are finite and will need to be replaced in the future. The possible sources of energy which can be used in place of fossil fuels each have their own advantages and disadvantages. In chapter 12, we will learn the energy from fossil fuels. This chapter also provide a description of the various types of fossil fuels including their sources and methods used for their extraction.

  • This could be fortuitous at modest scales because oxygen is relatively costly (Consonni and Larson 1994a). However, for the production of methanol from biomass, the use of air increases the volume of inert (N 2 ) gas that would have to be carried through all the downstream reactors. Therefore, the use of oxygen thus improves the economics of synthesis gas processing. Air-fired, directly heated gasifiers are considered not to be suitable before methanol production. This gasifier produces a CO 2 rich gas.

  • When will the oil run out? Various estimates put this anywhere from 20 years from now to more than a century in the future. The shortfall in energy might eventually be made up by developments in nuclear fusion, fuel cells, and solar technologies, but what can substitute for gasoline and diesel in all the internal combustion enginepowered vehicles that will continue to be built worldwide until then? And what will stand in for petrochemicals as sources of building blocks for the extensive range of “synthetics” that became indispensable during the twentieth century?...

  • Hydrogen fuel cells are one of the most promising alternatives to internal combustion engine hybrids and pure battery electric power for propelling passenger vehicles. Compared to internal combustion engine hybrid vehicles burning hydrocarbon fuels, fuel cell vehicles offer three primary advantages. First, the fuel cell system produces no tank-to-wheel carbon dioxide emissions and no other harmful emissions such as oxides of nitrogen, carbon monoxide, or particulates. Second, the fuel cell system offers the potential for approximately 30% higher well-to-wheel energy efficiency.
