    Sammanfattning : Catalytic combustion is an environmentally benign technologywhich has recently reached the stage of commercialization.Palladium is the catalyst of choice when considering gasturbines fuelled with natural gas because of its superioractivity for methane oxidation. LÄS MER

  3. 2. Oxygen formation in the chlorate process and preparation and deactivation of ozone selective anodes

    Författare :Staffan Sandin; Ann M. Cornell; Paul Christensen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATO; EOP; ozone; electrode preparation; elec- trode deactivation; hypochlorite; chlorate; oxygen; chromium VI ; sodium dichromate; electrocatalysis; catalysis; Chemical Engineering; Kemiteknik;

    Sammanfattning : This thesis presents experimental studies concerning two differ-ent electrolytic processes. One part deals with the electrochemicalformation of ozone and focuses on the preparation and deactiva-tion of a highly ozone-selective metal oxide anode (NATO - nickeland antimony doped tin oxide).
