1. 1. Utilization of Biomethane in Decarbonising India´s Energy Mix

   University essay from KTH/Energiteknik

   Author : Niraj Ravindra Kunkulol; [2023]
   Keywords : Anaerobic digestion; biogas; biomethane; membrane filtration; pressure swing adsorption; Anaerob rötning; biogas; biometan; membranfiltrering; trycksvängadsorption;

   Abstract : This thesis investigates the potential of biomethane production in India, the impact of its integration into the energy mix, and the corresponding Greenhouse Gases (GHG) emission and potential reduction. India, with its huge population and being an agriculturally rich country, produces gigantic amounts of biodegradable waste from various sources such as Municipal Solid Waste (MSW),agricultural waste, animal husbandry, sugar industry, etc. READ MORE

3. 2. Anaerobic Co-digestion of steam pretreated wheat straw and sewage sludge

   University essay from Lunds universitet/Bioteknik (master); Lunds universitet/Bioteknik (CI)

   Author : Virginia Tosi; [2021]
   Keywords : Anaerobic co-digestion; wheat straw pretreatment; nutrients availability; OLR; VFA acumulation; Biotechnology; Technology and Engineering;

   Abstract : Anaerobic digestion (AD) of wastes and residues is a widely applied and explored process. However, when the process is not optimized, inadequate concentrations of nutrients and inhibitory compounds are common and can lead to low maximum organic loading rates and increased risk of process problems, low organic dry solids degradation rate and reduced methane yields.

4. 3. Review and Design Adaptations of a SrCl2-NH3 bench-scale Thermochemical Heat Storage system

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Hjörtur Brynjarsson; [2021]
   Keywords : Thermochemical heat storage TCS ; SrCl2-NH3; system design; kinetics; absorption; desorption; octaammine; diammine; monoammine; pressure management; commissioning; Termokemisk värmelagring TCS ; SrCl2-NH3; systemdesign; kinetik; absorption; desorption; oktaammin; diammin; monoammin; tryckhantering; driftsättning;

   Abstract : Thermochemical heat storage (TCS) is a thermal energy storage (TES) technology used to store thermal energy for later use. TCS can provide heating or cooling services from intermittently available thermal energy, often low grade waste heat. READ MORE

5. 4. Modeling and optimisation of a rotary kiln reactor for the processing of battery materials

   University essay from KTH/Kemiteknik

   Author : Danial Khawaja; [2021]
   Keywords : Granular flow; rolling mode; suspension model; two-fluid model; multiphase flow; Granulärt flöde; rullningsläge; suspensions modell; tvåvätskemodell; flerfasmodell;

   Abstract : Roterugnar är cylindriska kärl som används för att höja materials temperaturer i en kontinuerlig process som kallas för kalcinering. Roterugnar kan tillämpas i olika processer såsom reduktion av oxidmalm samt återvinning av farligt avfall. READ MORE

6. 5. Use of Agricultural Wastes as Supplementary Cementitious Materials

   University essay from KTH/Byggvetenskap

   Author : Ezio Marchetti; [2020]
   Keywords : Agricultural waste; Environmental impact; Concrete; Life Cycle Assessment; Oat husk ash; Rice husk ash; Supplementary cementitious materials; Sustainable Construction; Betong; Havreskalaska; Hållbar konstruktion; Jordbruksavfall; Kompletterande cementmaterial; Livscykelanalys; Miljövarudeklaration; Miljöpåverkan; Risskalaska;

   Abstract : Global cement production is continuously increasing from 1990 till 2050 and growing particularly rapidly in developing countries, where it represents a crucial element for infrastructure development and industrialisation. Every tonne of ordinary Portland cement (OPC) produced releases, on average, about 800 kg of CO2 into the atmosphere, or, in total, the overall production of cement represents roughly 7% of all man-made carbon emissions.
