3. 12. CO, CO2 and N2 hydrogenation reactions probed by operando x-ray photoelectron spectroscopy

   Författare :David Degerman; Anders Nilsson; Miquel Salmeron; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Operando Catalysis; Hydrogenation reactions; High-Pressure X-Ray Photoelectron Spectroscopy; Syngas; kemisk fysik; Chemical Physics;

   Sammanfattning : Catalytic reactions are essential for generating the chemical products required by the modern society. In particular, reactions related to clean energy storage and generation as well as fertilizer production are facilitated by catalysts. However, the processes are often insufficiently understood at a mechanistic level. LÄS MER

4. 13. Black liquor gasification : burner characteristics and syngas cooling

   Författare :Mikael Risberg; Mats Lindblom; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

   Sammanfattning : Black liquor gasification at high temperature is a promising alternative to the conventional recovery boiler process used in chemical pulp mills today. Compared to a conventional recovery boiler a black liquor gasifier can increase the total energy efficiency of a chemical pulp mill and produce a synthesis gas that can be used for production of motor fuel.

5. 14. Biomass to Biofuel : Syngas Cleaning and Biomass Feedstock

   Författare :Ramiar Sadegh-Vaziri; Matthäus Bäbler; Per Alvfors; Lilian de Martin; Longcheng Liu; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gas-Solid Reaction; ZnO Sul_dation; Outward Growth; Hollow Particles; Algae Flocculation; PBEs; Fractal Clusters; Restructuring of Clusters; Deposition of Clusters; Primary Particle Aggregation.;

   Sammanfattning : This thesis builds around the idea of a biofuel production process that is comprised of biomass production, biomass gasification, gas cleaning, and fuel production. In this work, we specifically looked into H2S removal as a part of cleaning the producer gas and flocculation of microalgae which is involved in the harvesting of microalgae after biomass production.
