2. 1. Steam Explosion of Wood

   Author : Muhammad Muzamal; 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; finite element model; Steam explosion; biorefinery; pretreatment; wood;

   Abstract : The rising price of petroleum and environmental concerns regarding CO2 emissions has increased interest in alternative renewable resources. Biomass can be considered as an excellent alternative raw material. A biorefinery uses biomass and produces fuel, energy and value-added chemicals. READ MORE

4. 2. Mild Steam Explosion of Norway Spruce

   Author : Kerstin Jedvert; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; kraft cooking; biorefinery; steam explosion; galacto glucomannan; Norway spruce;

   Abstract : The most common wood species in Sweden, and one of the most important renewable raw materials in Northern Europe, is Norway spruce (Picea abies). Today, it is utilized mainly for sawed timber and the production of pulp and paper. READ MORE

5. 3. Molecular-level Simulations of Cellulose Dissolution by Steam and SC-CO2 Explosion

   Author : Faranak Bazooyar; Högskolan i Borås; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; molecular modelling; cellulose; steam explosion; SC-CO2 explosion; Resource Recovery; Resource Recovery; Resursåtervinning;

   Abstract : Dissolution of cellulose is an important but complicated step in biofuel production from lignocellulosic materials. Steam and supercritical carbon dioxide (SC-CO2) explosion are two effective methods for dissolution of some lignocellulosic materials. Loading and explosion are the major processes of these methods.

6. 4. Turbulent burning, flame acceleration, explosion triggering

   Author : V'yacheslav Akkerman; Vitaly Bychkov; Geoffrey Searby; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Turbulent combustion; flame acceleration; detonation explosion triggering; direct numerical simulations; Physics; Fysik;

   Abstract : The present thesis considers several important problems of combustion theory, which are closely related to each other: turbulent burning, flame interaction with walls in different geometries, flame acceleration and detonation triggering. The theory of turbulent burning is developed within the renormalization approach. READ MORE
