  1. 1. Towards Abatement of Selected Emissions from Metals Manufacturing

    Detta är en avhandling från Stockholm : KTH

    Författare :Diana Orrling; KTH.; [2010]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mercury; zinc; iron; copper; sulfur dioxide; adsorption; pollution; spectroscopy; thermal desorption; polycrystalline; surfaces; TECHNOLOGY Materials science; TEKNIKVETENSKAP Teknisk materialvetenskap;

    Sammanfattning : Although the metallurgical industry has made great strides in the reduction of unwanted emissions to the atmosphere as a result of production processes, significant challenges still exist. From a global perspective, even large reductions in emissions per produced ton become immaterial when considering that the total world production of metals continues to increase. LÄS MER
