Evaluating possible industrial applications of combustible shales and shale ash wastes

Article preview

Today energy consumption is constantly growing while explored reserves of easily accessible oil are depleting, which is a reason why most countries tend to diversify their energy mix, develop non-hydrocarbon energy sources and use domestic types of fuel, including the low grade ones. Thereby interest is raised to such a source of hydrocarbons as combustible shales. Combustible shales appear to be one of the highest-potential types of organic raw materials, which may offset and in future even substitute oil products and gas. The paper is investigating behavior and structure of combustible shales during heat treatment in order to identify their possible industrial applications. A synchronous thermal analysis has been held, chemical composition of combustible shales’ mineral fraction and optimal conditions for shale fines briquetting have been determined.

Examination of the raw materials and the products of the combustible shales processing

Article preview

The reserves of combustible slates of Russia in shale oil and gas equivalent are more than the reserves of oil and natural gas. The formation of a large volume of ash is a major problem connected to the processing and the usage of the combustible slates. It is possible to look at this problem from a different angle of vision if a mineral part of slates is considered as a complex  organo-mineral raw material where a  mineral substance of the slates is the same raw material as the organic one. For this purpose, it is required to study in detail the physicochemical characteristics of the combustible slates and the behavior of the organic and the mineral parts of the slates during the heat treatment. This research focuses on the phase composition of Leningrad fuel shale and its changes on pyrolysis. They were studying the phase composition, the gas phase outlet, pyrolysis mass balance of combustible slates in the nitrogen atmosphere in the temperature range of 200-1000 °С, the porosity changes of combustible slate in the nitrogen atmosphere in the temperature range of 25-900 °С. It is determined that the main minerals of combustible slates are calcite (28 %), quartz (25 %), illite (17 %), and microcline (11 %). The temperature dependence of the shale porosity is studied in a nitrogen atmosphere and in air. The porosity changes in four stages: (I) 25-200 °C; (II) 200-400 °C; (III) 400-600 °C; (IV) 600-900 °C. The mass balance pyrolysis of combustible slates in a PTK_1.2_40 tube furnace is made up, in the nitrogen atmosphere of 200, 400, 600, 800 and 1000 °C.

Heat of fusion and the symmetry of the potential of crystal structure of metals

Article preview

Simmetry transformation crystalline structure proceeds by symmetry reactions. Unlike the chemical reactions that proceed in the liquids and the gases where ions or atoms move freely symmetry reactions proceed in solid bodies where structural units are set orderly.

Analysis of data on crystallochemical nature of the phases of the copper-nickel matte аnd a binary system Со–S

Article preview

The task of the colour metallurgy is the complex utilization of the ore matirial  and  increase in volume of the production with fall of the material expenditures in parallel in unit of the production. During the sulphate ores refining and the nickel and copper ones they extract cobalt, pre- cious and the part of the rare metals, trying realize the very possible cobalts and small part of the ores raws transfer to the nickel product. However nickel can not be separated from copper completely with help of the flotation and that is why they get the sulphate nickel product which has the weight to 4 % of the copper and the copper sulphide concentration with weight 3-6 %. Together with nickel turn the part of the cobalt into the copper  concentration. In the school and reference books there are little scientific well-founded and coordinated facts in phases compound of the stanes and finestanes and besides  about formes of the presence of  the cobalt in the called metallurgy  products.  It is necessary the deep experience in the study of the christall chemical nature of the finestanes phases for the improvement in extract of cobalt to the nickel product during the flotation process.

Processing of manganiferous raw material producing high-quality product

Article preview

At the present time the demand of manganese is high in Russia. Metallurgy industry lacks of high quality manganese products. They make strict requirements to manganese concentrates for phosphorous content. It is possible to increase the quality of manganese concentrates and to use law-quality manganese raw material in the processing by means of hydrometallurgical processing.
