The metallurgical industry is one of the largest CO2 emitting industries. In order to reduce the CO2 footprint of the steel production process Tata Steel developed HIsarna: a process which reduces the CO2 emission by 20%. The Works Arising Gases (WAGs) of the HIsarna process have a rich CO2 concentration and the temperature is very high (~1500°C)1. The CO2 production of this process can be reduced by valorizing these waste streams.

The goal of this project is to investigate two solid catalysts for a two-staged thermochemical CO2 hydrogenation reaction: CO2 will be converted into methane and subsequently into aromatics. An autothermal reactor will be designed to take advantage of the high-temperature HIsarna off-gas to drive the strongly endothermic methane dehydroaromatization reaction (CH4 to aromatics).

This project is co-funded by Tata Steel and M2i.
