项目摘要

Steel is a critical material when transitioning to a more circular economy due to its inherent recyclability whilst maintaining its properties. However, the steel industry contributes 7-8% of the global anthropogenic CO2 emissions. The problem the steel industry faces is reducing emissions whilst increasing supply to meet additional demand. It is key that this paradox is solved to prevent the CO2 emissions being "off-shored" which does not actually solve the problem. Carbon capture utilisation and storage (CCUS) has been shown to be technically feasible via a series of studies whereby CO2 emitted is captured processed and utilised as a feedstock to produce another material, examples being primary alcohols and aviation fuels.Technologies such as pressure swing absorption and sorption enhanced water gas shift have been shown to be effective in capturing and separating the gaseous emissions from the process and there have been some successes in producing useful chemicals from the clean CO2 stream via biological and catalytic processes.This study will capture process gases and develop processes to yield a 'clean' hydrogen and CO2. The CO2 will then be valorised into new products (e.g. methane). The rationale for production of methane is to utilise as a reductant in Direct Reduced Iron (DRI) production which is a forerunner in the potential solutions to reduce emissions from primary iron and steelmaking.

由于其固有的可回收性在维护其性质的同时，钢是至关重要的材料。但是，钢铁行业占全球人为CO2排放量的7-8％。钢铁行业面临的问题是减少排放，同时增加供应以满足额外需求。解决此悖论以防止二氧化碳排放是“分离”的关键，这实际上并不能解决问题。碳捕获利用和储存（CCU）已被证明是通过一系列研究在技术上是可行的，通过一系列研究，将发射的二氧化碳被捕获并用作产生另一种材料的原料，例如主要的酒精和航空燃料。技术性燃料和航空研究（例如，从某些过程中都表现出了一些成功的水，并且在其上既可以捕获又有效果，从而有效地捕获了同种生产。通过生物学和催化过程从干净的CO2流中有用的化学物质。这项研究将捕获工艺气体并开发过程以产生“清洁”的氢和CO2。然后，二氧化碳将被称为新产品（例如甲烷）。甲烷生产的基本原理是用作直接降低铁（DRI）生产的还原剂，这是减少原代铁和钢制成的潜在解决方案的先驱。
