“…Incineration can result in the generation of highly toxic polychlorinated dibenzofurans/dibenzodioxins [16,17] and the primary measures in combustor design and technology to minimize the generation of "products of incomplete combustion" (PICs) cannot guarantee compliance with future legislated emissions [18]. Photocatalysis, ozonation and supercritical water oxidation represent advanced oxidation technologies that are showing promise as remediation technologies [19][20][21] but are still hampered by practical considerations and have a high-energy demand [22]. Catalytic steam reforming is emerging as a feasible methodology [23] but is again destructive in nature, albeit there is the possibility of generating synthesis gas as product.…”

“…The inner cavity has a diameter of 12 Å . The ZSM-48 zeolite has a ten-membered ring channels with a one-dimensional pore system and medium pore size (5.3-5.8 Å ) [17]. The Pt/HY catalysts have large pore openings and accordingly produce multi-branched iso-paraffin relatively easily, which is highly prone to cracking.…”

“…Numerous solids have been evaluated as catalysts for SCWO [45]. Copper(I)oxide on zeolites with different pore systems was tested as catalyst for SCWO of 2-chlorophenol, a highly toxic and degradation-resistant model contaminant [46,47]. Product shape selectivity observed during conversion over these zeolites was evident from the lower selectivities for polychlorinated and polyaromatic compounds compared to the noncatalytic reaction (see Tab ZSM-48 with a unidimensional pore system proved superior to the likewise medium-pore zeolite ZSM-5 with a three-dimensional pore system and the large-pore zeolite Y.…”
