1. 1. Climate change mitigation from biochar production at farm level : A time dynamic LCA study of wheat

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Louise Jungefeldt; [2022]
   Keywords : Pyrolysis; agricultural by-products; life cycle assessment; waste valorization; carbon sequestration;

   Abstract : Agricultural production in Sweden account for a large contribution of the territorial GHG emissions. System optimization, fossil fuel removal and increased circularity is therefore of great importance in order to reach the national net zero emission target by 2045. READ MORE

4. 3. Upgrading of Waste Tire Pyrolysis Oil

   University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

   Author : Surapat Somsri; [2018]
   Keywords : ;

   Abstract : The annual increase in waste car tires in addition to the enormous amount at present poses a major waste management problem as well as an environmental hazard. However, pyrolysis is emerging as a solution for waste tire management and a viable technology for material recycling and energy recovery that produces high energy liquid and gas products as well as char.

   Keywords : Biomass; bio-oil; bio-crude; hydrodeoxygenation; pyrolysis and tar cracking.;

   Abstract : This thesis evaluates the possibility to use a iron-based catalyst as a pyrolysis vapour conversion catalyst. The iron catalyst was also compared with the mineral dolomite. READ MORE

6. 5. Effects of tempering on corrosion properties of high nitrogen alloyed tooling steels in pyrolysis oil

   University essay from KTH/Korrosionslära

   Author : Ashkan Reza Gholi; [2011]
   Keywords : High nitrogen alloyed tooling steel; Pyrolysis; Tempering process; Primary and secondary chromium precipitates; Pitting corrosion; General corrosion;

   Abstract : Nowdays biofuels are becoming a good alternative for petroleum fuels due to environmental issues like high carbon dioxide emission and increasing vehicles population, together with the high price and fast depletion of petroleum oils. This project aims to investigate the corrosive effects of wood Pyrolysis oil on a special grade of nitrogen alloyed tooling steels to be used for injector nozzles in Diesel engines, where high stress and strain encounter high acidity and corrosivity of the Pyrolysis oil and cause breakdown over short periods.
