2. 1. Dirty coal: Industrial populism as purification in Poland's mining heartland

   Author : Irma Allen; Sverker Sörlin; Sabine Höhler; Christopher Hann; KTH; []
   Keywords : HUMANIORA; HUMANITIES; HUMANIORA; HUMANITIES; coal; populism; Poland; Silesia; environmental humanities; postsocialism; History of Science; Technology and Environment; Historiska studier av teknik; vetenskap och miljö;

   Abstract : In the second half of the 2010s, far-right populist parties gained increasing power and influenceacross Europe, and around the world. Core to their ethnonationalist, anti-elite agenda, and theiremotive politics, has often been a defense of fossil fuels, threatening action to address the climatecrisis and raising the spectre of fascism.

4. 2. Leaching of Polycyclic Aromatic Hydrocarbons Using a Column Method

   Author : Anja Enell; Avdelningen för kemiteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kemiteknik och kemisk teknologi; Naturvetenskap; Chemical technology and engineering; Natural science; Miljöstudier; Environmental studies; coal tar; PAHs; desorption; soil; combustion residues; remediation; availability;

   Abstract : Polycyclic aromatic hydrocarbons (PAHs) are a group of organic pollutants of great environmental concern, due to their toxicity, carcinogenicity and long persistence in the environment. To determine the potential risk associated with PAHs released from contaminated soil or waste materials, knowledge is required on the leachable concentrations of PAHs and the amounts available for release.

5. 3. Catalytic tar cleaning of biomass-derived gas with simultaneous catalyst regeneration

   Author : Fredrik Lind; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Tar cleaning; Catalytic gas cleaning; Biomass gasification;

   Abstract : Tar cleaning of raw gas from biomass gasification is a necessary operation before the gas can be used as feedstock for synthetic fuels. The technology for gas cleaning that is commercially available today (scrubber systems), is associated with problems like heat penalties and loss of the chemically stored energy within the tars.

6. 4. Thermally homogenous gasification of biomass/coal/waste for medium or high calorific value syngas production

   Author : Anna Ponzio; Wlodzimierz Blasiak; Petr Stehlik; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Metallurgical process engineering; Metallurgisk processteknik;

   Abstract :  Today’s problems with emissions of green house gases, land filling of waste and depletion of the oil reserves calls for new energy systems based on alternative fuels like biomass and waste. Gasification is an attractive technology for the use of such solid fuels. READ MORE

7. 5. Egypt Ignited : How Steam Power Arrived on the Nile and Integrated Egypt into Industrial Capitalism (1820s-76)

   Author : Amr Ahmed; Humanekologi; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Energy history; history of technology; environmental history; steam power; capitalism; Industrial Revolution; Global warming; Egypt; modern history; agrarian production; biofuels; Sugar industry; cotton; Energihistoria; Teknikhistoria; Miljöhistoria; Ångmaskin; Kapitalism; Industriella revolutionen; global uppvärmning; Egypten; Modern historia; Jordbruksproduktion; biobränslen; Sockerindustrin; Bomull;

   Abstract : How did fossil-fuelled technology find its way to Egypt on its way to global dominance? This thesis presents a socioecological history of energy technologies in agrarian production in pre-colonial Egypt (1820s – 76). It situates them in the nineteenth century, understood as the beginning of the epoch of the Capitalocene; and in Egypt’s case, this is simultaneously part of the rise of Britain’s fossil empire.
