2. 21. On the oxidation of kraft pulp - Formation of carbonyl groups during acidic hydrogen peroxide oxidation

   Author : Axel Martinsson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bleaching; Hydrogen Peroxide; wet-strength; cellulose oxidation;

   Abstract : A shift from fossil based to bio based raw material is necessary if the needs of a growing population are to be fulfilled sustainably. Today, the packaging industry is heavily dependent on products originating from fossil feedstocks. READ MORE

4. 22. Integration of first and second generation bioethanol processes using edible filamentous fungus Neurospora intermedia

   Author : Ramkumar B Nair; Högskolan i Borås; []
   Keywords : First- and second-generation bioethanol; Integration; Neurospora intermedia; Edible filamentous fungi; Wheat straw; Wheat bran; Whole stillage fiber; Biochemistry; Biokemi;

   Abstract : Establishing a commercial, lignocellulose-based, second-generation ethanol process has received several decades of attention by both researchers and industry. However, a fully economically viable process still remains a long-term goal. READ MORE

   Author : Jerry Luis Solis; Yohannes Kiros; Mohammad Taherzadeh; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Second-generation biofuels; biodiesel; heterogeneous catalysts; non-edible oils; ethanol; residual biomass; native yeast strains.; Andra generationens biobränslen; biodiesel; heterogena katalysatorer; oätliga oljor; etanol; rester av biomassa; naturliga jäststammar; Chemical Engineering; Kemiteknik; Energy Technology; Energiteknik;

   Abstract : Despite the global positive impacts of soybean-, maize- and sugarcane-based (first-generation) liquid biofuels, several drawbacks pertaining to increased use of agricultural land, causing deforestation in some countries and extensive practice of fertilizers have been observed. As a result, developing advanced (second- and third-generation) liquid biofuels have been identified as better alternatives and are considered to be of great importance in the future. READ MORE

6. 24. Techno-economic analysis of integrated biomass gasification for green chemical production

   Author : Jim Andersson; Anders Hultgren; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

   Abstract : Production of renewable motor fuels and green chemicals is important in the development towards a more sustainable society where fossil fuels are replaced. The global annual production of methanol and ammonia from fossil fuels is very large. READ MORE

7. 25. Generation of synthesis gas for fuels and chemicals production

   Author : Per Tunå; Avdelningen för kemiteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Synthetic fuels and chemicals; gasification; gas conditioning; simulation; tar-cracking;

   Abstract : Many scientists believe that the oil production will peak in the near future, if the peak has not already occurred. Peak oil theories and uncertain future oil deliveries have stimulated interest in alternative sources of fuel and chemicals. READ MORE
