6. DME som förnybart drivmedel till jordbruket : en studie i möjligheten att ersätta fossil diesel i jordbruksmaskiner med DME från bio-baserad råvara
Kandidat-uppsats, SLU/Dept. of Biosystems and Technology (from 130101)Sammanfattning : Sverige har satt som mål att nettoutsläpp från fossila bränslen ska vara borta till 2045 och mycket behöver göras för att Sverige ska uppnå det målet. Det går att konstatera att Sverige går snabbt framåt med att byta ut fossila bränslen i fordon och har redan nått en nivå på 23 % biokomponenter i drivmedel, den högsta nivån bland länderna i Europeiska Unionen.

7. Feasibility study for a 300kW pilot scale hydrogen production process from wood biomass : The case of Sandviksverket, Växjö
Master-uppsats, Linnéuniversitetet/Institutionen för byggd miljö och energiteknik (BET)Sammanfattning : Historically, fossil fuel sources (coal, oil and natural gas) have played significant role in meet global energy demand. As global population continue to rise, more and more energy resources are needed and there is a continuous depletion of these energy resources. LÄS MER
8. Fly larvae composting of fibrous food industry waste : impact of pre-treatment
Master-uppsats, SLU/Department of Molecular SciencesSammanfattning : With increasing population worldwide comes higher demands of food and greater waste generation. Effective ways for safe nutrient recycling and waste treatment are thus needed to minimize the human impact on the environment. LÄS MER
9. Future development of bioenergy in South Africa : A study of increased use of available biomass for the future development of renewable energy in South Africa
Uppsats för yrkesexamina på avancerad nivå, Mälardalens högskola/Akademin för ekonomi, samhälle och teknikSammanfattning : The development of renewable energy has become increasingly important as countries strive to become less dependent on fossil-derived energy. Biomass accounts for a large part of energy derived from renewable energy sources in Africa. LÄS MER
10. Modelling the Production of Biofuels via Olefins Oligomerisation
Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)Sammanfattning : The technical feasibility of gasoline and diesel range hydrocarbons production through oligomerisation of olefins, starting from biomass with the intermediary steps of gasfication, water-gas shift reaction and syngas-to-olefins synthesis was investigated, through mathematical modelling and simulation on Matlab. The model for the gasifier was based on minimisation of Gibbs free energy and its results showed that higher carbon efficiencies could be achieved at lower pressures and steam inlet, and more inlet energy, by pre-heating the gasifying agents.
