Nickel-based catalysts for steam reforming of naphthalene utilizing gasification slag from municipal solid waste as a support

Upcycling plastic waste into syngas: development of gasification slag supported NI catalysts for steam reforming of pyrolysis gas

“…In contrast, the doping of catalyst with Cr or W did not demonstrate positive effect in terms of coke resistance as reported in the literature (Bangala et al, 1998, Borowiecki and Gołcebiowski, 1994, Garcia et al, 2000. The novelty in Ni-Mo was the formation of reducible species (Ni2Mo3O8), which was not observed in previous study (Teoh et al, 2019a). This had led to the possible formation of Ni-Mo alloy and enhanced metal-support interaction, improving catalytic activity and coke resistance.…”

“…Figure 2a shows the XRD patterns of the slag support and Ni-based catalysts. In the XRD pattern of slag, no peaks corresponding to crystalline phases were present as this is a vitrified material with amorphous structure (Teoh et al, 2019a). For the Nibased catalysts supported on slag, NiO (PDF 89-7101), NiAl2O4 (PDF 10-0339) and gehlenite (Ca2Al2SiO7, PDF 87-0968) were the major crystalline phases detected (Table 1).…”

“…On the other hand, slag derived from gasification of municipal solid waste (MSW) was employed as the catalyst support to valorize the waste. Also, the components in slag including SiO2, MgO, Al2O3, CaO and TiO2 are suitable material as catalyst support (Tanigaki et al, 2012, Teoh et al, 2019b. It was also reported that Ni catalysts supported on slag have excellent coke resistance and high catalytic activity for tar conversion (Yu et al, 2017).…”

Catalytic Activity and Coke Resistance of Gasification Slag-Supported Ni Catalysts during Steam Reforming of Plastic Pyrolysis Gas

“…The slag was dried, crushed, and sieved to a particle size fraction of 100–300 μm. Based on previous studies of slag-supported catalysts and other types of catalysts, , metal loadings of 5–10 wt % were suitable to ensure efficient reforming. In terms of calcination conditions, it was shown that the mechanical strength and crystallization degree of catalysts increase as the calcination temperature increases but at the risk of sintering. − Hence, an intermediate calcination temperature of 700 °C under air atmosphere was selected.…”

“…This paper was cited in publications on the preparation of glass-containing foams from geopolymers [122] and vitrified MSWI bottom ash [123] in which the formation of wollastonite and the freezing of the microstructural evolution were mentioned. Other papers cited this publication with respect to the recycling of glass waste into foam glass [124][125][126][127][128][129], porous waste glass for lead removal in wastewater treatment [130], lead stabilization through alkali activation and sintering of Pb-bearing sludge [131], utilization of waste glass for the production of sulphuric acid resistant concrete [132], mechanical and alkali activation of MSWI fly and bottom ashes for the production of low-range alkaline cement [133] and foam glass-ceramics [134], inorganic gel casting for manufacturing of boro-alumino-silicate glass foams [135], porous glass-ceramics derived from MgO-CuO-TiO 2 -P 2 O 5 glasses [136], alkali activation of coal and biomass fly ashes [137], nickel-based catalysts for steam reforming of naphthalene utilizing MSW gasification slag as support [138], production of porous glass ceramics from titanium mine tailings and waste glass [139], porous bioactive glass microspheres [140], Al-SiO 2 composites [141], glass-ceramic foams from alkali-activated vitrified MSWI bottom ash and waste glasses [142]. Another study used vitrified MSWI bottom ash as input material to obtain similar porous glass ceramics [143] and was cited by some of the publications that also cited the first study.…”
