   Sammanfattning : In the transition to a sustainable energy supply there is an increasing need to use biomass for replacement of fossil fuel. A key challenge is to utilize biomass conversion technologies in an environmentally sound manner. LÄS MER

3. 2. The relationship between fly ash chemistry and the thermal formation of polychlorinated pollutants during waste incineration

   Författare :Duong Ngoc Chau Phan; Stellan Marklund; Bogdan Dlugogorski; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Incinerations; dioxins; PCDD Fs; PCBs; PCNs; flue gas; fly ash; sampling; particle characterization; XPS; XRD; SEM EDX; formation; chlorination; PCA; OPLS; OPLS-DA;

   Sammanfattning : The thermal formation of polychlorinated dibenzo-p-dioxins (PCDDs), dibenzofurans (PCDFs), biphenyls (PCBs), and naphthalenes (PCNs) is a major problem in waste incineration. Ideally, rather than relying on air cleaning systems and treatment techniques, their formation should be minimized or, if possible eliminated. LÄS MER
