1. 1. Characterization of NiMo catalysts with noble metal promoters

   University essay from Lunds universitet/Kemiteknik (CI)

   Author : Filip Hallböök; [2023]
   Keywords : Catalysis; Hydrodeoxygenation; TPR; NiMo-catalysts; Chemical engineering; Chemistry;

   Abstract : 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. READ MORE

3. 2. Nanoscale characterisation of model Ni-Mo catalyst active phases

   University essay from Lunds universitet/Centrum för analys och syntes

   Author : Jonas Elmroth Nordlander; [2022]
   Keywords : Ni-Mo catalysts; Hydrodeoxygenation; TEM; PXRD; Materials chemistry; Chemistry;

   Abstract : An important stepping stone in transitioning from a fossil-fuel based transportation system is the production of bio-fuels such as bio-oils. For bio-oils to be commercially viable, catalytic upgrading via hydrodeoxygenation is required, typically using Ni-Mo oxide or sulfide catalysts. READ MORE

4. 3. Low-carbon hydrogen production from waste plastics via pyrolysis and in-line catalytic cracking process

   University essay from KTH/Kraft- och värmeteknologi

   Author : Yanghao Jin; [2022]
   Keywords : Pyrolysis; catalytic cracking; plastics recycling; biochar catalyst; hydrogen production; Pyrolys; katalytisk krackning; återvinning av plast; biokol; produktion av väte;

   Abstract : This study develops a novel pyrolysis process combined with in-line catalytic reforming toproduce high purity hydrogen and carbon products from waste plastics. The input resource is waste plastic material in the form of discarded Covid masks. READ MORE

5. 4. Fast Pyrolysis of Biomass in a Fluidized Bed for Production of Bio-oil and Upgradation by Ex-situ Catalytic Bed

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

   Author : Samina Gulshan; [2019]
   Keywords : ;

   Abstract : Production of bio-oil from biomass is now becoming best substitute of fossil fuels in the transportation sector. Pyrolysis is one of the most promising route to produce bio-oil from biomass.  However, bio-oil needs to be upgraded due to presence of high percentage of oxygenated compounds. READ MORE

6. 5. Catalytic Upgrading of Fast Pyrolysis Bio-oil Using Zeolites

   University essay from KTH/Kraft- och värmeteknologi

   Author : Elena Wikberg; [2019]
   Keywords : ;

   Abstract : Fast pyrolysis bio-oil is considered as a possible source for production of liquid bio-fuels and bio-chemicals enabling the necessary transition to a renewable energy system. In this Master’s thesis work the upgrading of fast pyrolysis bio-oils with Fluid Catalytic Cracking (FCC) conversion process at industrially relevant conditions is studied using Fluid Catalytic Cracking Micro Activity Test (FCC MAT) unit at RISE ETC in Piteå, Sweden.
