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

   Master-uppsats, KTH/Kraft- och värmeteknologi

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

   Sammanfattning : 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. LÄS MER

3. 2. Catalytic Graphitization of Biomass : For the Production of Graphite Materials

   Kandidat-uppsats, KTH/Materialvetenskap

   Författare :Daniel Andersson; André Brunnberg; Emil Lind; [2021]
   Nyckelord :;

   Sammanfattning : In recent years the material graphite has been heavily studied since its use in widespread applications have increased, for example batteries, vehicles, and solar cells. When the need for this type of material increases the efficiency and the sustainability of the production methods must be taken into consideration. LÄS MER

4. 3. Iron-catalyzed graphitization of biochar to produce graphitic carbon materials

   Master-uppsats, KTH/Materialvetenskap

   Författare :Ziyi Shi; [2021]
   Nyckelord :graphite; biochar; catalyst; catalytic graphitization; grafit; biokol; katalysator; katalytisk grafitisering;

   Sammanfattning : Demand for high-quality graphite is expected to experience an extraordinary growth rate, in large part due to its wide range of industrial applications such as adsorbents, lubricants, electrodes, etc. This thesis developed a novel sustainable approach to produce green-graphite materials by applying biochar, acarbon-rich valuable by-product obtained from biomass, as a carbon precursor.
