1. 1. Investigations on Membrane Fouling and Cleaning in Ultrafiltration Processes in Lignocellulosic Biorefineries

   Författare :Gregor Rudolph; Avdelningen för kemiteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Membrane fouling; Membrane cleaning; Ultrafiltration; Online monitoring; Galactoglucomannan; Wood extractives; QCM-D; Lignocellulosic biomass; pulp and paper;

   Sammanfattning : The current fossil-based economy must be transformed into a bio-based circular economy. A cornerstone of this transformation is the conversion of pulp and paper mills into lignocellulosic biorefineries that allow not only the production of pulp, paper, and electricity, but also novel biochemicals.

3. 2. Immersed flat-sheet membrane bioreactors for lignocellulosic bioethanol production

   Författare :Amir Mahboubi; Huu Hao Ngo; Högskolan i Borås; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lignocellulosic bioethanol; immersed membrane bioreactor; membrane fouling; reverse membrane bioreactor; Resource Recovery; Resursåtervinning;

   Sammanfattning : The rising awareness of the environmental, economic and socio-political impacts of over-exploitation of fossil-based fuel and energy sources, have motivated the transition toward more sustainable and renewable energy sources. Lignocellulosic materials (e.g. LÄS MER

4. 3. Membrane Filtration of Lignocellulosic Materials: In situ Monitoring of Membrane Fouling Using Fluid Dynamic Gauging

   Författare :Kenneth Gacutno Arandia; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wood components; Membrane fouling; Fluid dynamic gauging; Cross-flow filtration;

   Sammanfattning : The transition of process industries from utilizing fossil-based resources to bio-based ones necessitates energy-efficient and selective operations. One practical operation that can be employed for processing streams containing lignocellulosic biomass, such as forest and agricultural residues, is membrane separation. LÄS MER

5. 4. Membrane Filtration of Wood Components − Investigation of Fouling Layer Characteristics using Fluid Dynamic Gauging

   Författare :Kenneth Gacutno Arandia; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fluid dynamic gauging; wood components; cross-flow filtration; steam explosion; microcrystalline cellulose; membrane fouling;

   Sammanfattning : As process industries transition from using fossil-based to bio-based resources, energy-efficient and highly selective operations will be required to process lignocellulosic biomass. Membrane separation, as a highly efficient operation, can be employed in the fractionation and dewatering of streams containing lignocellulosic biomass. LÄS MER

7. 5. Fermentative hydrogen and methane productions using membrane bioreactors

   Författare :Julius Akinbomi; Högskolan i Borås; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Encapsulation; Inhibition; hydrodynamics; hydrogen; methane; fruit flavour; Membrane bioreactor; Resursåtervinning; Resource Recovery;

   Sammanfattning : The role of energy as a stimulant for economic growth and environmental sustainabilityof any nation has made the focus on green fuels, including fermentative hydrogen (bioH2) andmethane (bioCH4), to be a priority for the World’s policy makers. Nigeria, as the most populousAfrican country, with worsening energy crisis, can benefit from the introduction of the bioH2 andbioCH4 technologies into the country’s energy mix, since such technologies have the potential ofgenerating energy from organic wastes such as fruit waste.
