  • Thermochemical reactor design and thermal breakdown in middle-rank coals

    Experiments conducted at bench scale can throw new light on the operation of pilot and plant scale processes. In the coal gasification/combustion area, such experiments have ranged from determinations of coal reactivities for novel entrained-flow gasifiers, to investigating the fate of injectant coal during blast furnace operation. Meanwhile, the accurate mimicking of conditions within pilot and ...

  • Impact of alkaline oxide on coal ash fusion temperature

    Ash fusion temperature (AFT) is an important index for coal gasification. A blend of fluxing agent with coal can decrease the AFT to meet the requirements of specific gasification process. Effect of alkaline oxide and silica alumina ratio on decreasing AFT is focused in this study. Simulation ash was used to investigate the effect of alkaline oxide on AFT. The experimental results showed that ...

  • Value of nuclear power in the global energy system

    With a global energy model which finds the minimum cost energy system over the time range of 1995-2055, the value of nuclear power is analysed. The model incorporates detailed descriptions of energy conversion technologies. For nuclear technologies, light water reactors and fast breeder reactors are taken into account with fuel cycle options. Major findings are: 1) the maximum introduction of ...

  • A review of non–renewable energy options in Illinois

    The State of Illinois has the largest non–renewable (fossil) energy reserves among all the states in the USA. We report our studies on coal, oil and gas energy resources, conversions, consumptions and carbon dioxide sequestration advances in Illinois from the point of view of sustainability in energy and environmental. This includes reserves and characteristics of coal, oil and gas in the ...

  • China must be encouraged to develop hydrogen energy and fuel cell technology using domestic resources

    This paper describes the current situation in China and the reasons for the rapidly increasing consumption of oil and the consequent search for new sources. Some suggestions are made for the rapid development and commercialisation of hydrogen energy systems in China using domestic resources. China could satisfy the energy demand with her domestic resources of renewable energies and depending on ...

  • Analysis of the organic contaminants in the condensate produced in the in situ underground coal gasification process

    Addressing the environmental risks related to contamination of groundwater with the phenolics, benzene, toluene, ethyl benzene, xylene (BTEX) and polycyclic aromatic hydrocarbons (PAHs), which might be potentially released from the underground coal gasification (UCG) under adverse hydrogeological and/or operational conditions, is crucial in terms of wider implementation of the process. The aim ...

  • Thermodynamic performance simulation of a coal gasification and SOFC based combined cogeneration plant by energy and exergy analyses

    This paper presents a thermodynamic model of a combined cogeneration plant that employs a coal gasifier, a gas cooler and a solid oxide fuel cell (SOFC) upstream of the gas turbine and a downstream HRSG to generate process steam at low pressure. Simulated performance of the plant with respect to variations in some design and operating parameters has been reported. While energy analysis indicates ...

  • Evaporator reduces wastewater volume for dakota gasification

    Evaporator integral to stringent zero liquid discharge (zld) waste requirements American Natural Gas (ANG) developed a coal gasification project in Beulah, North Dakota in the early 1980’s to produce pipeline gas and various other products. Basin Electric, the local utility, acquired the plant in 1988 and renamed it Dakota Gasification. The Problem ...

  • Performance analysis of a co-gasifier for organic waste in agriculture

    Background:Agricultural waste has been proposed as an alternative energy resource to meet fossil fuel crisis, green house emission, and other environmental impacts worldwide. In Iran, rice husk and bagasse are main resources of biomass which can be used to produce syngas. This paper deals with a simplified model of combined gasification of coal and biomass processes considering chemical ...

  • Laboratory scale tests of coal-based hydrogen production with CO2 capture in the aspect of clean coal technologies

    In the light of continuously increasing oil prices as well as stronger environmental regulations, an important issue becomes finding an alternative to fossil fuels. Scientists agree that hydrogen seems to be an ideal, price-competitive and environment-friendly future energy carrier. One of the most effective methods of hydrogen production is the process of steam gasification of coal to ...

  • Is `clean` coal possible?

    VANCOUVER, April 18, 2007 (GLOBE-Net) - Coal is the world’s most commonly used fuel to produce electrical energy, and will continue as such for some time. Yet it is one of the ’dirtiest’ of all fossil fuels. It is a major source of toxic air pollutants and the leading source of energy-related greenhouse gas emissions. Many believe ’clean coal’ technologies will improve the energy efficiency of ...
