1. 1. Purification of Engineered Graphite for Advanced Application

   University essay from KTH/Materialvetenskap

   Author : Lingfeng Zhao; [2022]
   Keywords : Graphite; Purification; Acid washing; Biomass; Biochar;

   Abstract : Graphite has important applications in several key industries, which has been listed as a “criticalraw material” considered to be supply-risk by European since 2020. Purification of engineered graphite is one of the essential processes for the manufacturing of high-quality graphite. READ MORE

3. 2. Techno-economic evaluation of hydrochar via hydrothermal carbonisation of organicresidues

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Abdirahman Abdullahi; [2022]
   Keywords : Technoeconomic analysis; energy system modelling; HTC; hyrochar; system integration; OSMET;

   Abstract : This thesis has investigated the techno-economic feasibility of upgrading the sludge from a chemical pulp mill to hydrochar via hydrothermal carbonization (HTC). The intended use of the hydrochar was to replace fossil coal within metallurgical applications in the iron and steel industry. READ MORE

4. 3. Improving Availability of the Pelletization Process

   University essay from Luleå tekniska universitet/Institutionen för ekonomi, teknik, konst och samhälle

   Author : Emil Andreasson; Pontus Åhman; [2022]
   Keywords : Availability; Predictive Maintenance; Pelletization; Statistical Process Control; Refractory Material; DMAIC;

   Abstract : The Grate-Kiln-Cooler process is a commonly used method of sintering during iron ore pelletization, where the pellets are formed, dried, and hardened. The pellets are oxidized in the rotating Kiln, turning magnetite (Fe3O4) to hematite (Fe2O3), making the pellets attain suitable metallurgical attributes for further processing. READ MORE

5. 4. Simulation of carbon- monoxide rich syngas through gasification and co-gasification of biomass.

   University essay from Umeå universitet/Institutionen för tillämpad fysik och elektronik

   Author : Musasa Kayiba Tracy; [2022]
   Keywords : Gasification; biomass;

   Abstract : Syngas is an interesting energy source for metallurgical processes, as an energy carrier syngas is an efficient way of utilizing the energy in biomass. Utilizing syngas in fuming processes as a carbon source instead of coal was an approach to minimize carbon dioxide emissions produced in the fuming process. READ MORE

6. 5. Online Metallurgical Mass Balance and Reconciliation

   University essay from Umeå universitet/Institutionen för fysik

   Author : Emil Andersson; [2021]
   Keywords : dynamic; froth flotation; mass balancing; mineral processing; reconciliation;

   Abstract : In mineral processing, one of the most important and versatile separation methods is flotation. Flotation utilizes the different surface properties of the valuable minerals in the ore to separate them from the less valuable gangue material in the ore. Crushed and ground ore is mixed with water and fed into flotation tanks. READ MORE
