1. 6. Calcium Oxide based Carbon Capture in District Energy Systems

   University essay from KTH/Kemiteknik

   Author : Mit Jayesh Vora; [2022]
   Keywords : BioCCS; BECCS; Post Combustion; Calcium looping CaL process; Techno-economic assessment; District heating;

   Abstract : Global carbon emissions are higher than ever before and in the last decade of 21st century, focus has shifted on reducing these emissions in various ways possible. Carbon capture, utilization and storage (CCUS) has been identified as one of the important ways to reduce carbon emissions and meet climate targets. READ MORE

3. 7. Chemical Kinetic Modeling of the Combustion of NH3/H2 and NH3/syngas Fuel Mixtures Using a Large Amount of Experimental Data

   University essay from Lunds universitet/Kemiska institutionen

   Author : Andras Szanthoffer; [2022]
   Keywords : Ammonia combustion; Detailed chemical kinetic mechanisms; Quantitative mechanism comparison; Local sensitivity analysis; Chemical Physics; Chemistry;

   Abstract : Nowadays, due to the global climate change, it is extremely important to find alternative fuels to reduce the utilization of fossil fuels and the emission of air pollutants such as carbon dioxide (CO2), hydrocarbon pollutants, and soot. Ammonia (NH3) is a promising carbon free fuel candidate that can store and transport renewable hydrogen (H2) energy. READ MORE

4. 8. Negative CO2 Emissions from Chemical Looping Combustion: Gas Cleaning for CO2 Storage

   University essay from KTH/Kemiteknik

   Author : Laura Raud Pettersson; [2022]
   Keywords : Chemical Looping Combustion; Flue Gas Treatment; Negative emissions; Biomass; CCS; Linde Hampson; Cryogenic Separation; Kemcyklisk Förbränning; Rökgasrening; Negativa Utsläpp; CCS; Biomassa; Linde Hampson; Kryogen Destillation;

   Abstract : Kemcyklisk förbränning (CLC) involverar en icke komplex separation av den bildade koldioxiden (CO2) efter förbränningen eftersom syret (O2) överförs till bränslet via en syrebärare som cirkulerar mellan luft- och bränslereaktorn. Eftersom O2 separeras effektivt från kvävgasen (N2) i luftreaktorn, erhålls en produkt gas som till majoriteten består av CO2 och vatten (H2O). READ MORE

5. 9. 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. 10. Techno-economic Analysis of Biomass Conversion to Hard Carbon Materials

   University essay from KTH/Materialvetenskap

   Author : Yuxin Liu; [2022]
   Keywords : Biomass; hard carbon production; process simulation; Aspen plus; techno-economic analysis; Biomassa; produktion av hårt kol; processimulering; Aspen plus; teknoekonomisk analys; Biomassa; produktion av hårt kol; processimulering; Aspen plus; teknoekonomisk analys;

   Abstract : Hard carbon is an important material for future fossil-free transport systems, as it is a popular choice for the production of anodes for sodium-ion batteries. Biomass is a popular carbonaceous raw material for making hard carbon. READ MORE
