1. 1. Stability improvement to a ruthenium catalyst for partial oxidation of methane

   University essay from Lunds universitet/Kemiteknik (CI)

   Author : Melker Axelsson; [2023]
   Keywords : catalysis; reaction engineering; kinetics; partial oxidation; chemical engineering; Technology and Engineering;

   Abstract : Catalytic partial oxidation of methane (CPOM) is an energy-efficient alternative to steam reforming, the currently prevailing method for energy production from natural gas. Hulteberg Chemistry & Engineering AB has developed a catalyst for the partial oxidation of methane into syngas, for use in solid oxide fuel cells. READ MORE

3. 2. Screening pyrolysis bio-oil as binder for carbon anode in aluminium production

   University essay from KTH/Fiber- och polymerteknologi

   Author : Yazhe Wang; [2023]
   Keywords : Biomass; Bio-oil; Bio-pitch; Carbon Anode; Aluminum production; Biomassa; Bioolja; Biobeck; Kolanod; Aluminium Produktion;

   Abstract : Den högkvalitativa stenkolstjäran, som används som anodbindemedel inom aluminiumindustrin, innebär utmaningar när det gäller att möta kraven på kolanod. Dess produktion är beroende av ohållbara fossila bränslen, vilket bidrar till ökade koldioxidutsläpp. READ MORE

4. 3. Residual Products in the Steel Industry Used for Briquetting

   University essay from KTH/Materialvetenskap

   Author : Alexander Eriksson; Linn Isaksson; Jacob Lilliebjörn; [2023]
   Keywords : ;

   Abstract : This report looks at the implementation of briquetting in the Swedish steel industry. Briquetting is a process in which residual products are mixed and compressed into a brick-like body in order to be added to the melt in a furnace. This report investigates the type of materials commonly used in briquetting as of today. READ MORE

5. 4. German coal exit : an argumentative discourse analysis of storylines and discourse coalitions

   University essay from SLU/Dept. of Urban and Rural Development

   Author : Amelie Andresen; [2023]
   Keywords : German coal exit; coal phase-out act; energy transition; discourse analysis; storylines; discourse coalition;

   Abstract : Germany passed a Coal Phase-out Act in 2020 to reduce carbon emissions and to achieve the objec-tives of the Paris Agreement, at a time when Germany was already phasing out nuclear energy. Thus, Germany faces a dual challenge: not only to break its dependence on coal as a resource, but also the overlap of the phase-outs of nuclear and coal energy. READ MORE

6. 5. Reprocessing and Characterization of Polybenzimidazole for High-Temperature Polymer Electrolyte Membrane Fuel Cells

   University essay from Lunds universitet/Centrum för analys och syntes

   Author : Douglas Björkengren; [2023]
   Keywords : polymer electrolyte membrane fuel cells; PEMFC; HTPEMFC; polymer technology; polymer characterization; reprocessing; recycling; polybenzimidazole; PBI; Technology and Engineering;

   Abstract : A reprocessing method of poly(2,2’-(m-phenylene)-5,5’-bibenzimidazole) (PBI) membranes recovered from the production line of High-Temperature Polymer Electrolyte Membrane Fuel Cells (HT-PEMFC) at Blue World Technologies (BWT) has been developed in order to reduce material loss in the production. Redissolution of scrap PBI membranes in poly(phosphoric acid) (PPA) and phosphoric acid (PA) was successful and the subsequent washing procedure produced PBI that could be redissolved in N,N-dimethyl acetamide (DMAc) and suitable for solution casting of new membranes.
