1. 1. On Heat and Paper : From Hot Pressing to Impulse Technology

   Författare :Marco Francesco Carlo Lucisano; KTH; []
   Nyckelord :Paper; Impulse Drying; Heat Transfer; Phase Change; Heat-Pipe Effect; Delamination; Flashing;

   Sammanfattning : Impulse technology is a process in which water is removedfrom a wet paper web by the combined action of mechanicalpressure and intense heat. This results in increased dewateringrates, increased smoothness on the roll side of the sheet, andincreased density. LÄS MER

4. 3. Exit choice in fire emergencies - Influencing choice of exit with flashing lights

   Författare :Daniel Nilsson; Avdelningen för Brandteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Theory of Affordances.; green flashing lights; active evacuation systems; affiliation; exit choice; evacuation; egress; Fire;

   Sammanfattning : Fire accidents and evacuation experiments have revealed that people often use familiar exits in fire emergencies. However, the design of emergency exits has also been shown to impact people’s choice of exit. LÄS MER

5. 4. Superheated Steam Drying of Wood Chips in Pneumatic Conveying Dryers

   Författare :Christian Fyhr; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; superheated steam; drying; pneumatic conveying; convective; non-spherical particles; wood; heat transfer;

   Sammanfattning : This thesis contains a fundamental investigation of a pneumatic conveying dryer. The model presented can be used both for design and rating purposes and, although the main emphasis is put on the drying of wood chips in superheated steam, the results can be used for other systems as well.

7. 5. Citrus Waste Biorefinery: Process Development, Simulation and Economic Analysis

   Författare :Mohammad Pour Bafrani; Mohammad Pourbafrani; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; process simulation; encapsulated yeast; Citrus wastes; economic analysis; computational fluid dynamic simulation; pectin; limonene; methane; ethanol;

   Sammanfattning : The production of ethanol and other sustainable products including methane, limonene and pectin from citrus wastes (CWs) was studied in the present thesis. In the first part of the work, the CWs were hydrolyzed using enzymes – pectinase, cellulase and β-glucosidase – and the hydrolyzate was fermented using encapsulated yeasts in the presence of the inhibitor compound ‘limonene’.
