COPPER BASED ALLOY RESISTANT AGAINST METAL DUSTING AND ITS USE

摘要

A copper-base alloy, which is resistant or immune to carburization, metal dusting and coking, resistant to oxidation and said alloy having the following composition (all contents in weight-%): Al > 0-15; Si >= 0-6; Mg >= 0-6, one or more of the group of Rare Earth Metal (REM), yttrium, hafnium, zirconium, lanthanum, cerium up to 0.3 weight-% each Cu balance and normally occurring alloying additions and impurities and use of said alloy as construction components in CO-containing atmospheres, and/or hydrocarbon containing atmospheres or solid carbon containing processes, for example, gasification of solid carbonaceous materials, thermal decomposition of hydrocarbons and catalytic reforming, particularly, catalytic reforming under low-sulfur, and low-sulfur and low-water conditions and which is resistant to loss of material by copper vaporization.
