5. 4. Enhanced Catalytic Pyrolysis of Biomass for High-Quality Biofuel Production

   Författare :Devy Kartika Ratnasari; Weihong Yang; Pär Jönsson; Tobias Richards; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Al-MCM-41; lignocellulose biomass; H-ZSM-5; kinetic study; catalyst regeneration;

   Sammanfattning : The rapid increase in energy demand, the extensive use of fossil fuels, and the urgent need to reduce carbon dioxide emissions have raised concerns in the transportation sector, since transportation has been primarily dependent on fossil fuels. Biofuel from biomass can make significant contributions to overcome the expected depletion of fossil fuels and reduce carbon emissions. LÄS MER
