The paper presents the results of studies to determine the effect of complex surface and bulk modification and double filtration during mould pouring on the stereological parameters of macrostructure and mechanical properties of castings made from the post-production waste IN CN86107592A - Immersion combustion in melted material A kind of with oxygen and fuel spray into material is housed the molten bath to heat the method for this melt substance.The temperature in this molten bath is higher than the fuel spontaneous ignition temperature, have the ring curtain of a part of fuel formation around oxygen at least, and combustion fuel is to provide heat to melt substance.When melt substance is unpurified copper, can
Mar 13, 2019 · Production of multifunctional industrial textiles that are lightweight, high/low-temperature resistant and chemical-resistant, with high performance and good light fastness, using non-woven, weaving, knitting or their composite techniques. 24. Dyeing and after finishing processing of high-end textiles, using advanced energy conservation and Closing the Nutrient Cycle in Two-Stage Anaerobic Industrial waste streams from brewing industries and distilleries provide a valuable but largely unused alternative substrate for biogas production by anaerobic digestion. High sulfur loads in the feed caused by acidic pretreatment to enhance bioavailability are responsible for H2S formation during anaerobic digestion. Microbiological oxidation of H2S provides an elegant technique to remove
Ferroaluminum, a dense and highly efficient aluminum addition, contains 30-40% Al. It is supplied in lump form, 8 in. x 4 in., 5 in. x 2 in., 5 in. x D, and 2 in. x D, and nominal 12 lb. and 25 lb. pigs, packed in drums and pallet boxes. Finally, so-called "synthetic" slags containing calcium aluminate are available. Glossary of Steel Industry Terms - American Iron and Steel Category of steel that includes electrical (see Silicon Electrical Steel), alloy (see Alloy Steel), stainless (see Stainless Steel), and tool steels (see Tool Steels). Specialty Tube. Refers to a wide variety of high-quality custom-made tubular products requiring critical tolerances, precise dimensional control and special metallurgical properties.
When total sulfur removal is requked, it is not uncommon that 20 to 30 percent excess carbide is employed. The excess carbide then ends up as slag and creates a disposal problem. If the kon were desulfurized only to the extent actually needed, much of this waste could be reduced or eliminated (Stephens 1988). Investing in China Legal Issues |Catalogue of Industries May 08, 2021 · 22. Comprehensive utilization of industrial by-product gypsum. 23. Development and application of new technologies for comprehensive utilization of nonmetal mine tailings; and ecological restoration of mines (XV) Nonferrous Metals Smelting and Rolling Industry. 1. Production of silicon single crystals and polished wafers with 200mm or larger
184.108.40.206 Industrial Progress. Before the breakthrough of secondary metallurgy in the 19601970s, special steel was refined in EAFs after melting and oxidizing refining slag was removed, the steel was deoxidized, new lime-rich slag was formed, and steel was desulfurized to quite low contents to Metal Industry Glossary - Industrial Controls, Motor Silicon Steel. Steel usually made in the basic open-hearth or electric furnace, with about 0.50-5.% silicon, other elements being usually dept as low as possible. Because of high electrical resistance and low hysterisis loss, silicon sheet and strip are standard in electric magnet manufacture. Siliconizing

The present invention relates to a supported catalyst system for the removal of sulfur compounds, such as H2S comprising a metal compound on a support material, wherein in said support material, the sum of the pore volume present in micro-pores and in mesopores is less than 0.20 ml per gram of catalyst, and wherein the pore volume V-Hg, as measured by mercury intrusion porosimetry, is at least Terry J. McGenity Kenneth N. Timmis Balbina Nogales genated chemicals for industrial applications and represent impor-tant tools for bioremediation . During the dehalogenation a proton is liberated at the expense of a single water molecule so the enzymatic reaction can be followed because of the protons pro-duced, which, in turn, can be monitored by a pH indicator. 1.
