Coal-to-Liquids (CTL) can supply liquid fuels and have been successfully used in several cases, particularly in South Africa. This article reviews CTL theory and technology. Understanding the fundamental aspects of coal liquefaction technologies are vital for planning and policy-making, as future CTL systems will be integrated in a much larger global energy and fuel utilization system. Conversion ratios for CTL are generally estimated to be between 1-2 barrels/ton coal. This puts a strict limitation on future CTL capacity imposed by future coal production volumes, regardless of other factors such as economics, emissions or environmental concern.

  • Principles of Selectivity in Fischer-Tropsch SYNTHESIS Hans Schulz Engler-Bunte-Institute, University of Karlsruhe Kaiserstrasse 12, 76128 Karlsruhe, Germany
    DGMK/SCI-Conference „Synthesis Gas Chemistry", October 4-6, 2006, Dresden, Germany Principles of Selectivity in Fischer-Tropsch SYNTHESIS Hans Schulz Engler-Bunte-Institute, University of Karlsruhe Kaiserstrasse 12, 76128 Karlsruhe, Germany Abstract The detailed selectivity of Fischer-Tropsch synthesis with iron and cobalt as catalysts with high temporal resolution has been determined and used to derive the values of probability of chain growth, chain branching and olefin/paraffin molar ratio as a function of carbon number and time. Catalyst reassembling and self-organization of the Fischer-Tropsch regime are i nvestigated. The basic principle of Fischer-Tropsch synthesis, suppression of desorption of growing chains is disclosed. This frustration governs FT-synthesis of the otherwise different systems with iron and cobalt. The advanced characterization of sites and elementary reactions (specifically with cobalt) is thought to be a more realistic basis for future theoretical calculations. Diesel fuel through Fischer-Tropsch synthesis The present interest in Fischer-Tropsch synthesis focuses on the production of Diesel fuel. Competing in coal liquefaction with hydrogenation [1], the FT-route now is superior because the fuel is very clean and exhibits excellent performance in the combustion engine (TABLE 1). However, the maximum selectivity is only ~ 40% C, as shown in Fig. 1 on the basis of calculating the theoretical product composition, assuming ideal polymerization kinetics with carbon number independent growth probability [2]. The overall Diesel selectivity can be increased to ~ 60% by running the FT-synthesis at high paraffin-wax selectivity (high growth probability pg) and mildly converting the paraffin wax through ideal hydrocracking.

  • Fischer-Tropsch Fuels from Coal, Natural Gas, and Biomass: Background and Policy
    Order Code RL34133 Fischer-Tropsch Fuels from Coal, Natural Gas, and Biomass: Background and Policy Updated March 27, 2008 Anthony Andrews Specialist in Energy and Energy Infrastructure Policy Resources, Science, and Industry Division Jeffrey Logan Specialist in Energy Policy Resources, Science, and Industry Division Fischer-Tropsch Fuels from Coal, Natural Gas, and Biomass: Background and Policy Summary As the price of crude oil sets a record high, liquid transportation fuels synthesized from coal, natural gas, and biomass are proposed as one solution to reducing dependency on imported petroleum and strained refinery capacity. The technology to do so developed from processes that directly and indirectly convert coal into liquid fuel. Congress now faces decisions on whether, and to what extent, it should support such a solution. Lacking domestic petroleum resources, but abundant in coal, Germany built synthetic fuel plants during World War II that employed the Bergius coal hydrogenation process (direct liquefaction), and Fischer-Tropsch synthesis (indirect). The United States attempted to capitalize on the German experience after World War II. Despite considerable investment in synthetic fuel research and development, the United States cut support for commercialization when crude oil prices dropped and supplies stabilized in the mid-1980s. Since then, several synthetic fuels plants have been constructed around the world that convert coal, natural gas, or biomass to liquid fuels using the Fischer-Tropsch process. Several private ventures in the United States are now studying the feasibility of constructing Fischer-Tropsch synthetic fuel plants based on coal, natural gas, and biomass. Proposals to expand the use of coal to synthesize transportation fuels have generated much opposition, particularly because the carbon dioxide (CO2) produced in the Fischer-Tropsch process is a greenhouse gas associated with global warming.

  • Friedrich Bergius and the Rise of the German Synthetic Fuel Industry
    Friedrich Bergius and the Rise of the German Synthetic Fue nI ustry By Anthony N. Stranges* G ERMANY HAS VIRTUALLY NO petroleumdeposits. Prior to the twen- tieth century that lack of a liquid fuel was not a serious problem, because Germany possessed abundantcoal reserves. Coal provided for commercial and home heating; it also fulfilled the needs of industryand the military,particularly the navy. In the first decade of the twentieth century, Germany's energy requirements began to change. Two reasons were especially important. First, Germany be- came increasinglydependent on gasoline and diesel oil engines. The appearance of automobiles, trucks, and then airplanes made a plentiful supply of gasoline absolutely essential; moreover, ocean-going ships increasingly used diesel oil rather than coal as their energy source. Second, Germany's continuing indus- trialization and urbanizationmagnified the shortcomings of coal as an energy source. German scientists and engineers began to replace coal with smokeless liquid fuels, which not only were cleaner burningand more convenient to handle but also had a higher energy content. Petroleumwas clearly the fuel of the future, and to insure that Germanywould never be without it, her scientists and engineers created a domestic source of that fuel. From a plentiful natural substance, coal, they synthesized petroleum. Of the several processes the Germansused to convert coal into petroleum, high- pressure coal hydrogenationwas the most highly advanced. Its history falls into two broad periods: 1910-1925, duringwhich time its inventor, FriedrichBergius (1884-1949) developed the process through the first stages of industrialization, and 1925-1945, the period of its further commercial development by German industrialists.

  • Presentation 80A Stranges Germany
    GERMANY’S SYNTHETIC FUEL INDUSTRIES Anthony Stranges Texas A&M University Department of History Abstract Germany’s Synthetic Fuel Industry 1930-1945 Abstract Petroleum was clearly the fuel of the future, and to insure that Germany would never lack a plentiful supply, German scientists and engineers synthesized petroleum from their country’s abundant coal supplies and thereby established the world’s first technologically successful synthetic fuels industry. Of the several conversion processes the Germans developed, high-pressure coal hydrogenation or liquefaction and the Fischer-Tropsch synthesis (F-T) were the most advanced. Friedrich Bergius (1884- 1949) launched the German program for energy independence with the invention of high-pressure coal hydrogenation in the years 1910-25. Franz Fischer (1877-1947) and Hans Tropsch broadened it with the gaseous synthesis of liquid fuels in the mid-1920s. IG Farben, Ruhrchemie, and others industrialized the German energy program with their development of the Bergius process and Fischer-Tropsch synthesis from the 1920s to the end of World War II. This paper examines Germany’s industrialization of the two synthetic fuel processes, analyzing their growth over several decades of social, political, and economic unrest. Overview SYNTHETIC FUELS IN GERMANY OVERVIEW 1911-1945 For the Fischer-Tropsch process the research and development falls into two divisions PERIOD ACTIVITY 1922-1935 Laboratory research and pilot plant development 1936-1945 Industrial-size development, with most of the development occurring

  • Aviation Gasoline Technology Transfer During the Second World War: Japan, Germany and the U.S.A
    Aviation Gasoline Technology Transfer during the Second World War: Japan, Germany and the U.S.A. Munehiro Miwa INTRODUCTION As an example of the reception of knowledge, let us consider the aviation gasoline production technologies, which were transferred over the boundaries of Allies vs. Axis Powers during the World War II. It is worthwhile to trace how Japan acquired the overseas methods from a web of newest and complicated technological information then available and developed its own technology. Detailed consideration reveals prejudiced assumptions, misleading reception of knowledge, technology transfer from enemy country, and other complex aspects. Why did Japan, specifically the Imperial Navy, believe that Germany succeeded in coal liquefaction by Bergius Process to produce aviation gasoline, and did not consider using low- temperature coal tar as the raw material? It is necessary to discuss the background and the reasons how the Naval Fuel Depot, which employed the most advanced technical staff in Japan at the time, led this move on the wrong assumption. The Navy doggedly insisted on the liquefaction process, spent enormous resources, and solicited the South Manchuria Railway Co., Ltd. (Fushun) and Nippon Chisso (Hungnam) to prepare for manufacture. The Navy showed interest in the information regarding the isooctane process, which came from the Universal Oil Products Company (“UOP”), and was actually able to show some results in production. However, it paid no heed to the similar, more efficient alkylation process, which played an important role in increased production of high-octane aviation spirit in the U.S. , in the Trinidad, in Abadan and in Germany during the war.
