熔融还原炼铁与清洁能源化工联合生产工艺

Combined Technology of Smelting Reduction Iron-Making and Clean Fuel Manufacture

熔融还原炼铁工艺直接使用非焦煤生产液态铁 ,具有流程短 ,投资和生产成本低 ,环境污染小 ,铁水质量好的优点 ,是面向 2 1世纪的前沿炼铁技术。结合一定的化工方法 ,将熔融还原炼铁工艺附产的大量煤气 ,转化成一种清洁能源二甲醚 ,可进一步提高熔融还原炼铁工艺过程的能量利用率。本文就熔融还原炼铁与清洁能源的联合生产工艺方法和特点进行了探讨。

Smelting reduction is a front iron making technology for the 21st century. It can produce liquid iron by direct using common coal instead of charred coal.The process has many attractive advantages,such as concise flow,low investment and production cost,low environmental pollution and high quality molten iron.Combined with a reciprocal chemical technology,energy efficiency can be further improved by transforming mass coal gas,byproduced in smelting reduction,into dimethyl ether, a clean fuel. Method and characteristics of the combined technology are discussed in this paper.
