1. Characterization of NiMo catalysts with noble metal promoters
Master-uppsats, Lunds universitet/Kemiteknik (CI)Sammanfattning : To be able to face the challenges brought on by climate change there is an urgent need to reduce the heavy dependence on fossil fuels. Bio-oil is one such renewable and carbon-neutral replacement that has shown promising potential. A key step in making bio-oil commercially feasible is improvements of the upgrading processes of the bio-oil. LÄS MER
2. High-loaded thermophilic anaerobic digestion of mixed sewage sludge : A pilot study
Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)Sammanfattning : Municipal wastewater treatment plants (WWTP) are important infrastructural components in a society and also important for sustainability. In a WWTP the most common treatment configuration is mechanical, biological, and chemical treatment of the wastewater. LÄS MER
3. Omställning från mesofil till termofil rötning på Hammarby Sjöstadsverket
Uppsats för yrkesexamina på grundnivå, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)Sammanfattning : I framtiden kommer belastning på Henriksdals avloppsreningsverk fördubblas, vilket innebär en ökning av antalet personer som bekännas, från cirka 800 000 till 1,6 miljoner. Hygienkravet på slam kommer även att bli striktare. LÄS MER
4. Small-scale biogas : A techno-economic comparison of Internal Combustion Engines, Micro Gas Turbines and Stirling Engines
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : Gas driven power generation is expected to increase in the near future due to significantly lesser environmental impact than oppose to conventional fuels like coal and oil. Today, Natural Gas (NG) is the dominant product on the market and biogas, which originates from degradable organic waste, has not reached its full market potential due to bottlenecks in utilization.

5. Performance monitoring of systems for airpuricationAuthor:Anders
Uppsats för yrkesexamina på avancerad nivå, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)Sammanfattning : Wastewater treatment plants (WWTP) are often the cause of malodor. The compounds which are the main causes of the odor is hydrogen sulfide (H2S), ammonia(NH3), mercaptans (RSH) and volatile organic compounds (V OC) [1]. The odorous air can be analyzed to determine the concentration of the odorants. LÄS MER
