2. 1. Bio-SNG from Thermal Gasification - Process Synthesis, Integration and Performance

   Author : Stefan Heyne; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; process integration; process modelling; performance indicators; biomass; energy systems; synthetic natural gas; gasification;

   Abstract : Biomethane or synthetic natural gas (Bio-SNG) produced from gasified renewable woody biomass is a promising option for replacing fossil natural gas. The complete interchangeability with natural gas in all its conventional applications such as in the power generation, transportation and chemical industry sector is of particular interest.

4. 2. Biomass conversion through syngas-based biorefineries : thermochemical process integration opportunities

   Author : Katarina Åberg; Anders Nordin; Linda Pommer; Erik Dahlquist; Umeå universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biomass; biorefinery; thermochemical conversion; torrefaction; slow pyrolysis; gasification; process integration; carbon negativity;

   Abstract : The replacement of fossil resources through renewable alternatives is one way to mitigate global climate change. Biomass is the only renewable source of carbon available for replacing oil as a refining feedstock. Therefore, it needs to be utilized not just as a fuel but for both biochemical and thermochemical conversion through biorefining. READ MORE

5. 3. Shaping Future Opportunities for Biomass Gasification - The Role of Integration

   Author : Johan Ahlström; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hydrogen; heat integration; Gasification; sawmill; SNG; power-to-gas; Biomethane; Biorefinery; process integration;

   Abstract : A considerable number of studies indicate that biofuels produced from lignocellulosic biomass will most probably play a significant role in achieving the climate goals stated in the Paris agreement. Several candidate technologies could be implemented to produce these fuels, and one of the most promising is thermal gasification. READ MORE

6. 4. Process Integration Opportunities for Synthetic Natural Gas (SNG) Production by Thermal Gasification of Biomass

   Author : Stefan Heyne; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biomass; synthetic natural gas; energy systems; process integration; renewable energy;

   Abstract : Synthetic natural gas (SNG) from gasified biomass is one promising option to produce renewable transport fuels. This thesis presents a process integration study investigating thermal gasification of biomass for the production of SNG and identifies critical conversion steps for the overall process performance.

7. 5. Chemical and Biochemical Biorefineries in Kraft Pulp Mills – Process Integration and Economics for Three Concepts

   Author : Valeria Lundberg; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bottleneck; ethanol; biorefinery; energy efficiency; process integration; pulp mill; high gravity;

   Abstract : Some of the advantages of integrating biorefinery concepts with kraft pulp mills are that the utility system can be shared and that mass and energy streams can be exported from the pulp mill to the biorefinery or vice versa. These measures may result in lower investments and operating costs for the biorefinery compared with stand-alone operations. READ MORE
