Spark Plasma

The regularities of the influence of sintering temperature, pressure and duration of isothermal holding during spark plasma sintering on the structure of Al2O3ceramics not containing activating additives are determined. The revealed interrelations made it possible to determine the direction of the search for the optimal parameters of the sintering regime and formulate the technological recommendations for the sintering of ingots for smallsized end mills.Ill. 4.

The process of anthracite and its semi-coke combustion in the presence of 5 wt.% (in terms of dry salt) additives of copper salts Cu(NO3)2 and Cu(CH3COO)2 was studied. The activating additives were introduced by an incipient wetness procedure. The ignition and combustion parameters for coal samples were examined in the combustion chamber at the heating medium temperatures (Tg) of 600–800 °C. The composition of the gaseous combustion products was controlled using an on-line gas analyzer. The fuel modification with copper salts was found to reduce the ignition delay time on average, along with a drop in the minimum ignition temperature Tmin by 138–277 °C. With an increase in Tg temperature, a significant reduction in the ignition delay time for the anthracite and semi-coke samples (by a factor of 6.7) was observed. The maximum difference in the ignition delay time between the original and modified samples of anthracite (ΔTi = 5.5 s) and semi-coke (ΔTi = 5.4 s) was recorded at a Tg temperature of 600 °C in the case of Cu(CH3COO)2. The emergence of micro-explosions was detected at an early stage of combustion via high-speed video imaging for samples modified by copper acetate. According to the on-line gas analysis data, the addition of copper salts permits one to reduce the volume of CO formed by 40% on average, providing complete oxidation of the fuel to CO2. It was shown that the introduction of additives promoted the reduction in the NOx emissions during the combustion of the anthracite and semi-coke samples.

Abstract USS 18-8 MoL (AISI Type 316L) is an austenitic chromium-nickel stainless with 2 to 3% molybdenum added for superior resistance to corrosion. It is formable and weldable. Its low carbon content virtually eliminates the hazard of intergranular corrosion after welding. Its many uses include chemical processing, petroleum refining and food processing. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as fracture toughness, creep, and fatigue. It also includes information on corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: SS-317. Producer or source: United States Steel Corporation.

Processing Petroleum

The processes of oil production and preparation involve the formation of a mixture of various hydrocarbon gases, otherwise called associated petroleum gas. Today most of associated petroleum gas produced is burned, causing damage to the natural environment, or used as an energy supply for technological equipment. At the same time, associated petroleum gas can be used as a valuable raw material to produce various chemicals. In the article, the existing methods of APG utilization are considered, and the relatively simplest and most environmentally friendly pyrolysis method is proposed. A comparative analysis of the methods of mixing raw materials was carried out, as a result of which it was revealed that the mechanical and vibration methods are considered the most rational. An experimental installation for processing petroleum associated gas by pyrolysis is presented. The results of experimental studies of the production of carbon fiber nanomaterials and hydrogen are presented. Gas (CH4) obtained by utilization of hydrocarbon-containing waste (oil sludge) was used as a feedstock. The average yield of the target products was 81 l/h for hydrogen and 325.5 g/h for nanofiber carbon.
