Operation Desert (German Fuel Project)
Operation Desert (german: Unternehmen Wüste) was a German synthetic fuel project during World War II. It attempted to build a shale oil industrial production complex for utilization of Swabian Alb oil shale deposits (Posidonia Shale). The project was driven by the fuel needs of the German army at the last phase of World War II due to decreasing conventional petroleum supplies. Three companies conducted pilot tests. ''LIAS-Ölschiefer-Forschungsgesellschaft mbH'', established in September 1942, started tests in Frommern. Holoch (1978), p. 232 ''Kohle-Öl-Union von Busse KG'', established on 30 July 1943 in Berlin, tested ''in-situ'' retorting on the outskirts of Schörzingen. Megargee (2009), p. 1012 ''Deutsche Ölschiefer-Forschungsgesellschaft mbH'', established on 20 September 1943 in Schömberg, became later the core of the Operation Desert. ''Schutzstaffel'' (SS) and Hermann Göring personally became involved in the project in late 1943. On 2 May 1944, SS established oi ...

Synthetic Fuel
Synthetic fuel or synfuel is a liquid fuel, or sometimes gaseous fuel, obtained from syngas, a mixture of carbon monoxide and hydrogen, in which the syngas was derived from gasification of solid feedstocks such as coal or biomass or by reforming of natural gas. Common ways for refining synthetic fuels include the Fischer–Tropsch conversion, methanol to gasoline conversion, or direct coal liquefaction. Classification and principles The term 'synthetic fuel' or 'synfuel' has several different meanings and it may include different types of fuels. More traditional definitions define 'synthetic fuel' or 'synfuel' as any liquid fuel obtained from coal or natural gas. In its Annual Energy Outlook 2006, the Energy Information Administration defines synthetic fuels as fuels produced from coal, natural gas, or biomass feedstocks through chemical conversion into synthetic crude and/or synthetic liquid products. A number of synthetic fuel's definitions include fuels produced from bi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shale Oil Extraction
Shale oil extraction is an industrial process for unconventional oil production. This process converts kerogen in oil shale into shale oil by pyrolysis, hydrogenation, or thermal dissolution. The resultant shale oil is used as fuel oil or upgraded to meet refinery feedstock specifications by adding hydrogen and removing sulfur and nitrogen impurities. Shale oil extraction is usually performed above ground (''ex situ'' processing) by mining the oil shale and then treating it in processing facilities. Other modern technologies perform the processing underground (on-site or ''in situ'' processing) by applying heat and extracting the oil via oil wells. The earliest description of the process dates to the 10th century. In 1684, Great Britain granted the first formal extraction process patent. Extraction industries and innovations became widespread during the 19th century. The industry shrank in the mid-20th century following the discovery of large reserves of conventional oil, ...

Peat
Peat (), also known as turf (), is an accumulation of partially decayed vegetation or organic matter. It is unique to natural areas called peatlands, bogs, mires, moors, or muskegs. The peatland ecosystem covers and is the most efficient carbon sink on the planet, because peatland plants capture carbon dioxide (CO2) naturally released from the peat, maintaining an equilibrium. In natural peatlands, the "annual rate of biomass production is greater than the rate of decomposition", but it takes "thousands of years for peatlands to develop the deposits of , which is the average depth of the boreal orthernpeatlands", which store around 415 gigatonnes (Gt) of carbon (about 46 times 2019 global CO2 emissions). Globally, peat stores up to 550 Gt of carbon, 42% of all soil carbon, which exceeds the carbon stored in all other vegetation types, including the world's forests, although it covers just 3% of the land's surface. ''Sphagnum'' moss, also called peat moss, is one of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mound
A mound is a heaped pile of earth, gravel, sand, rocks, or debris. Most commonly, mounds are earthen formations such as hills and mountains, particularly if they appear artificial. A mound may be any rounded area of topographically higher elevation on any surface. Artificial mounds have been created for a variety of reasons throughout history, including habitation (see Tell and Terp), ceremonial (platform mound), burial (tumulus), and commemorative purposes (e.g. Kościuszko Mound). Archaeology North American archaeology In the archaeology of the United States and Canada, a mound is a deliberately constructed elevated earthen structure or earthwork, intended for a range of potential uses. In European and Asian archaeology, the word "tumulus" may be used as a synonym for an artificial hill, particularly if the hill is related to particular burial customs. While the term "mound" may be applied to historic constructions, most mounds in the United States are pre-Columbian ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yield (chemistry)
In chemistry, yield, also referred to as reaction yield, is a measure of the quantity of Mole (unit), moles of a Product (chemistry), product formed in relation to the reactant consumed, obtained in a chemical reaction, usually expressed as a percentage. Yield is one of the primary factors that scientists must consider in organic synthesis, organic and inorganic chemical synthesis processes. In chemical reaction engineering, "yield", "Conversion (chemistry), conversion" and "selectivity" are terms used to describe ratios of how much of a reactant was consumed (conversion), how much desired product was formed (yield) in relation to the undesired product (selectivity), represented as X, Y, and S. Definitions In chemical reaction engineering, "yield", "Conversion (chemistry), conversion" and "selectivity" are terms used to describe ratios of how much of a reactant has reacted—conversion, how much of a desired product was formed—yield, and how much desired product was formed ...

Carbonization
Carbonization is the conversion of organic matters like plants and dead animal remains into carbon through destructive distillation. Complexity in carbonization Carbonization is a pyrolytic reaction, therefore, is considered a complex process in which many reactions take place concurrently such as dehydrogenation, condensation, hydrogen transfer and isomerization. Carbonization differs from coalification in that it occurs much faster, due to its reaction rate being faster by many orders of magnitude. For the final pyrolysis temperature, the amount of heat applied controls the degree of carbonization and the residual content of foreign elements. For example, at T ~ 1200 K the carbon content of the residue exceeds a mass fraction of 90 wt.%, whereas at T ~ 1600 K more than 99 wt.% carbon is found. Carbonization is often exothermic, which means that it could in principle be made self-sustaining and be used as a source of energy that does not produce carbon dioxide. In the case ...

Holmberg
Holmberg is a Swedish surname formed from the words ''holm(e)'' meaning islet and ''berg'' meaning mountain. It is a relatively common name, at least in Sweden, which has to do with the fact that many Swedish place names contain the suffixes ''-holm'', ''-holmen'' or ''-berg'', ''-berga'', ''-berget''. Notable people with the surname include: * Åke Holmberg (1907–1991), Swedish author and translator * Krister Holmberg (born 1946), professor of Surface Chemistry at Chalmers University of Technology * Anne Holmberg (born 1938), American writer of historical romance novels * Arvid Holmberg (1886–1958), Swedish gymnast who competed in the 1908 Summer Olympics * Barbro Holmberg (born 1952), Swedish Social Democratic politician * Birgit Agda Holmberg (born 1921), Swedish revue director, actress and singer * Bo Holmberg (1942–2010), Swedish politician, widower of former Swedish Minister for Foreign Affairs Anna Lindh (1957–2003) * Britta Holmberg (1921–2004), Swedish film act ...

Reichswerke Hermann Göring
Reichswerke Hermann Göring was an industrial conglomerate in Nazi Germany from 1937 until 1945. It was established to extract and process domestic iron ores from Salzgitter that were deemed uneconomical by the privately held steel mills. The state-owned Reichswerke was seen as a vehicle of hastening growth in ore mining and steel output regardless of private capitalists' plans and opinions, which ran contrary to Adolf Hitler's strategic vision. In November 1937, Reichsminister of Aviation Hermann Göring obtained unchecked access to state financing and launched a chain of mergers, diversifying into military industries with the absorption of Rheinmetall. Göring himself supervised the Reichswerke but did not own it in any sense and did not make personal profit from it directly, although at times he withdrew cash for personal expenses.Overy, p. 145. After the Anschluss, the Reichswerke absorbed Austrian heavy industries, including those owned by private German investors. The clu ...

Natzweiler-Struthof Concentration Camp
Natzweiler-Struthof was a Nazi concentration camp located in the Vosges Mountains close to the villages of Natzweiler and Struthof in the Gau Baden-Alsace of Germany, on territory annexed from France on a basis in 1940. It operated from 21 May 1941 to September 1944, and was the only concentration camp established by the Germans in the territory of pre-war France. The camp was located in a heavily-forested and isolated area at an elevation of . About 52,000 prisoners were estimated to be held there during its time of operation. The prisoners were mainly from the resistance movements in German-occupied territories. It was a labor camp, a transit camp and, as the war went on, a place of execution. Some died from the exertions of their labor and malnutrition – there were an estimated 22,000 deaths at the camp, including its network of subcamps. Many prisoners were moved to other camps; in particular, in 1944 the former head of Auschwitz concentration camp was brought in to eva ...

Nazi Concentration Camps
From 1933 to 1945, Nazi Germany operated more than a thousand concentration camps, (officially) or (more commonly). The Nazi concentration camps are distinguished from other types of Nazi camps such as forced-labor camps, as well as concentration camps operated by Germany's allies. on its own territory and in parts of German-occupied Europe. The first camps were established in March 1933 immediately after Adolf Hitler became Chancellor of Germany. Following the 1934 purge of the SA, the concentration camps were run exclusively by the SS via the Concentration Camps Inspectorate and later the SS Main Economic and Administrative Office. Initially, most prisoners were members of the Communist Party of Germany, but as time went on different groups were arrested, including "habitual criminals", "asocials", and Jews. After the beginning of World War II, people from German-occupied Europe were imprisoned in the concentration camps. Following Allied military victories, the ...
