Low emission iron and steelmaking using hydrogen to pre-reduce lump ore

该项目旨在开发和应用一种新的利用氢气或富氢气体对铁矿石进行预还原的方法，以减少钢铁生产中的二氧化碳排放。该路线将建立在铁矿石的H2还原动力学基础上，并采用CO2回收和热风加热H2等新技术，通过解决矿产和钢铁行业的环境问题来支持氢经济。这不仅对低碳钢生产具有重要意义，而且对未来发展零排放钢铁和氢气炼钢具有重要的基础性认识。该项目将是非常有益的，因为它增加了块铁矿石的使用，并扩大了澳大利亚的铁矿石出口。

This project aims to develop and apply a new route of lump iron ore pre-reduction with hydrogen or H2-enriched gases for ironmaking to minimise CO2 emission from steel production. The route will be built up on the base of H2 reduction kinetics of iron ore and with novel technologies such as CO2 recycle and H2-heating using hot blast, underpinning the hydrogen economy by addressing the environmental concerns in mineral and steel industries. It is not only significant for low-carbon steel production, but also for better fundamental understanding to develop the future zero-emission iron and steelmaking with hydrogen. The project will be very beneficent because it increases the use of lump iron ore and expends Australian export of iron ores.
