Internal Carbon Cycles in the Steel Industry: Pathways for CO2 Management and Carbon Capture Utilization

Chemie Ingenieur Technik, EarlyView.
The steel industry accounts for about 7%‐9% of global CO2 emissions. While H2‐based direct reduction is a long‐term route, near‐term solutions are needed for existing plants. Internal carbon cycles reuse steelworks off‐gases and by‐products, enabling circular carbon use and supporting CCU integration.

Composition of Purified CO2 From Steel Mill Processes—A Classification and Analytical Comparison With Commercial CO2

Chemie Ingenieur Technik, EarlyView.
Due to the severe catalyst poisoning effect of certain trace components, the purity of CO2 is the main attribute to qualify it as syngas for further downstream processes. This study uses PTR–MS to investigate the trace components of the CO2 produced within the Carbon2Chem project.

Application of artificial neural network and general machine learning modelling on CO2 adsorption in moisture equilibrated South African high and medium rank coals

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract This study investigates the effect of moisture on CO2 adsorption in South African coals using both experimental and machine learning approaches. Three coal samples (SL, TN, and EM) with varying ranks (RoVmr: 3.49%, 1.26%, and 0.64%, respectively) were collected from different regions of South Africa.
