  1. 36. Turbo Charged Low Temperature Combustion - Experiments, Modeling and Control

    Författare :Hans Aulin; Förbränningsmotorer; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HCCI; PPC; CAI; NVO; low temperature combustion; torductor; ion current; control; modeling; combustion feedback; sensors;

    Sammanfattning : Both the global economy and the society in general are dependent on the availability of reliable transportation. Most transportation technology involves the use of internal combustion engines in one way or another. LÄS MER

  3. 37. Deactivation of emission control catalysts for heavy-duty vehicles : Impact of biofuel and lube oil-derived contaminants

    Författare :Sandra Dahlin; Lars Pettersson; Isabella Nova; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NH3-SCR; Cu-SSZ-13; V2O5-WO3 TiO2; catalyst deactivation; diesel oxidation catalyst; sulfur; phosphorus; biodiesel; heavy-duty; emission control; regeneration; alkali metals; NH3-SCR; Cu-SSZ-13; V2O5-WO3 TiO2; katalysatordeaktivering; dieseloxidationskatalysator; svavel; fosfor; biodiesel; tunga dieselmotorer; avgasrening; regenerering; alkalimetaller; Chemical Engineering; Kemiteknik;

    Sammanfattning : Catalytic emission control is used to reduce the negative impact of pollutants from diesel exhausts on our health and on the environment. For a heavy-duty truck, such a system consists of a diesel oxidation catalyst (DOC), a diesel particulate filter (DPF), a selective catalytic reduction (SCR) catalyst, and an ammonia slip catalyst (ASC).

  4. 38. New Perspectives in Multi-trophic Aquaculture

    Författare :Matthew Hargrave; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; aquaculture; kelp; seaweed; IMTA; mussel; bioremediation; Saccharina latissima; Mytilus edulis; extractive aquaculture; biofouling; epiphytes;

    Sammanfattning : Aquaculture, the farming of marine and aquatic organisms, is currently the fastest growing food production sector globally. As capture fisheries have stagnated and the fishing down of marine food webs has been seen to be unsustainable, aquaculture is filling the deficit in providing food to a growing world population.

  5. 39. Vehicle emissions abatement: NO oxidation and ammonia SCR

    Författare :Xavier Auvray; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SpaciMS; NO oxidation; Cu-Beta zeolite; sulfur dioxide; Platinum; ammonia SCR; aging;

    Sammanfattning : The design and the development of catalytic systems for reducing vehicle emissions is a complex task due to the variety of components in a wide range of gas flow and temperature. A complete system is, therefore, composed of a series of catalysts or catalytic systems, each of which is dealing with a particular aspect of the abatement process. LÄS MER

  7. 40. Chemical composition of Arctic aerosols and their link to clouds

    Författare :Yvette Gramlich; Claudia Mohr; Paul Zieger; Ilona Riipinen; Ulrich Pöschl; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Arctic; aerosols; cloud residuals; mass spectrometry; biomass burning; Environmental Sciences; miljövetenskap;

    Sammanfattning : The Arctic is a place particularly vulnerable to climate change, warming at an accelerated rate compared to the rest of the Earth. In this remote environment, the atmosphere, the ocean, the ice, and the land are all interlinked and are shaping a very complex system. LÄS MER
