Destruction of chlorinated organic solvents in a molten carbonate with transition metal oxides

Steam gasification of printed circuit board from e-waste: Effect of coexisting nickel to hydrogen production

“…Yamawaki [29] concluded that gasification of plastic WEEE at high temperature (1423 K) followed by a shock cooling step is an effective process to decompose the brominated flame retardants (BFR) to comply with the minimum regulatory values. Yang et al [30,31] obtained similar results for the abatement of halogenated compounds by the oxidation of plastics at high temperatures (1173 K) in a molten carbonates reactor. Tongamp et al [32,33] studied a one-step mechanochemical treatment of plastics (673-823 K) to produce hydrogen gas, using Ni(OH) 2 as catalyst powder and CaO or Ca(OH) 2 for chlorine removal.…”

Scientific and Engineering Literature Mini Review of Molten Salt Oxidation for Radioactive Waste Treatment and Organic Compound Gasification as well as Spent Salt Treatment

“…The destruction of chlorinated organic solvents in a molten carbonate in the presence of floating powdered transition metal oxides was also reported [72,73,86]. At a given oxidation efficiency, the addition of the transition metal oxides to the molten salt reduced the operating temperatures.…”

Studies of Recycling of Poly(vinyl chloride) in Molten Na, Ca ‖ NO3, OH Systems

“…This allowed the formation of valuable liquid and solid fractions, such as liquid petroleum fractions, aromatic compounds, solid paraffins, and monomers. Yang et al [10] investigated the destruction of chlorinated organic solvents in a molten carbonate reactor, in which floating powdered transition metal oxides were present. The collection of chlorine in the molten salt did not change within the operating temperature range 750-950…”
