Article Synopsis
- The study focuses on using the heat from cooled iron ore pellets to produce metallized pellets for steelmaking without CO emissions, by reducing the pellets in hydrogen during cooling.
- As the cooling rate decreases, improvements are seen in iron content and metallization, while compressive strength first increases and then drops significantly.
- The cooling rate affects the particles' morphology and porosity, leading to larger, uniformly distributed metallic iron particles, with the optimal cooling rate of 3.7 °C/min providing a good balance of metallization and compressive strength.
Article Synopsis
- - The study explored how the flow rate of hydrogen during the hydrogen cooling reduction (HCR) process impacts the effectiveness of reducing iron ore pellets for steelmaking.
- - Increasing the hydrogen flow rate initially improved reduction performance, but too high a flow rate led to issues like gas diffusion resistance and decreasing reduction efficiency.
- - Optimal performance for metallized pellets was achieved at a hydrogen flow rate of 0.8 L/min, resulting in high reduction and metallization degrees, although compression strength decreased significantly past 0.6 L/min due to increased porosity and surface cracks.
Zika virus (ZIKV) is an emerging arbovirus with increasing prevalence in recent years. To reduce the risk of ZIKV transmission by transfusion, some mitigation strategies were recommended based on pathogen reduction technologies for blood products. In this study, we aimed to study the efficacy of several common pathogen reduction methods in the inactivation of ZIKV.
