Device and method for producing synthesis gas. Pietzarka, Friedrich Wilhelm; Meurer, Peter; Portz, Willi; Kampmann, Friedrich Wilhelm (Hoechst A.-G. ; Uhde G.m.b.H., Fed. Rep. Ger.). Ger. Offen. DE 3239774 A1 3 May 1984, 31 pp. (German). (Germany). CODEN: GWXXBX. CLASS: IC: C10J003-02; C10J003-20. APPLICATION: DE 82-3239774 27 Oct 1982. DOCUMENT TYPE: Patent CA Section: 51 (Fossil Fuels, Derivatives, and Related Products) Section cross-reference(s): 45, 47, 56 The title app. gasifies coal and produces CaC2 [75-20-7] or ferrosilicon alloy, depending on addn. of auxiliary materials. The coal and gasifying agent (e.g., CO2, steam, or synthesis gas) enter the bottom of the reactor and form a gasification zone surrounded by a redn. zone. Addnl. materials (e.g., coke and calcined limestone for CaC2 prodn., or Fe scrap for ferrosilicon prodn.) enter the top of the reactor and encounter a drying zone (with product synthesis gas) prior to entering the redn. zone. Raw by-products are removed from the bottom of the reactor, while entrained ash and dust are sepd. later from the gas.

How Western Foundry desulfurizes iron

How Western Foundry desulfurizes iron. Bissig, John C. (USA). Foundry Manage. Technol., 105(5), 92, 95 (English) 1977. CODEN: FNMTBS. ISSN: 0360-8999. DOCUMENT TYPE: Journal CA Section: 55 (Ferrous Metals and Alloys) The desulfurization process for the prodn. of better quality ductile cast iron [11097-15-7] by using CaC2 as the desulfurization agent is described. Best results are obtained when CaC2 [75-20-7] is directed to the area of the melt where the most agitation occurs. Based on a 5 tons/h iron melting rate, 2.5 lb/min or 1.66 lb/min of 1.5 or 1% CaC2 was used. The design of the system is described.
