Performance of RP-3 kerosene cracking over Pt/WO3–ZrO2 catalyst

Synthesis of a High-Stability Nanosized Pt-Loaded MgAl2O4 Catalyst for n-Decane Cracking with Enhanced Activity and Durability

“…Appropriate catalysts can increase the heat-absorption capacity by improving the selectivity of preferred products (like low-carbon alkenes) and conversion. Based on related literatures, − two kinds of catalysts, including pseudo-homogeneous catalysts − and wall-coated catalysts, − are broadly studied for the EHF cracking reaction.…”

“…Wall-coated catalysts are another kind of commonly used catalysts in EHF cracking at present, and the coatings are mainly concentrated in zeolites and composite oxides. − On the one hand, Liu et al, Ji et al., Sang and Li, Konno et al, and Diao et al . all found that ZSM-5 and modified ZSM-5 zeolites had a good catalytic effect on EHF cracking.…”

“…On the other hand, Pt- or/and Ni-based composite oxide catalysts with a large specific surface area and adjustable acidity have also become a research hotspot in this field; meanwhile, the light alkenes selectivity can be improved by adjusting the acidity and acid sites distribution. − Our group has studied the effects of various composite oxides catalysts, such as Pt/CeO 2 –Al 2 O 3 , Pt/WO 3 –ZrO 2 , Pt/ZrO 2 –TiO 2 , Pt­(MoO 3 )/ZrO 2 –TiO 2 –Al 2 O 3 , − and Pt–Ni/MoO 3 –La 2 O 3 –Al 2 O 3 on the cracking of RP-3 jet fuel and n -decane. Pt-based composite oxides significantly enhanced the heat sink, which is much better than thermal cracking (the highest heat sink is 3.93 MJ/kg at 750 °C), as well as can run stably for 20 min under high temperature, high pressure, and large flow rate conditions (750 °C, 3.5 MPa, 1.0 g/s).…”

Synthesis of MgO-ZrO2 Mixed Nanoparticles via Different Precursors: Identification of their Destructive Action for Organic Pollutants

“…Nanooxides play an important role in applied chemistry due to their vast applications such as semiconductors [1], biodiesel applications [2], catalytic application [3,4], biological applications [5], glaze applications [6], purification of oils [7] and photocatalytic degradation of organic pollutants [8][9][10][11][12]. Though many sorbents were tried for the decontamination of CWA's; viz activated carbon [13,14] or polymer [15,16], but the use of mixed metal oxide nanoparticles showed more satisfactory results [17,18] due to their high surface area, crystallinity, different morphologies and easily separation of electron hole pairs which are necessary for generating free radicals which decompose these organic pollutants [19].…”

Synthesis of MgO Nanoparticles from Different Organic Precursors; Catalytic Decontamination of Organic Pollutants and Antitumor Activity

“…Researches on the synthesis and application of nanomaterials had experienced tremendous growth in recent years, owing to their unique properties making them suitable for applications in almost every field of science [1][2][3][4][5][6][7][8][9][10][11]. Photocatalytic degradation of dyes and toxic organic materials from aqueous solution is considered one of the most effective methods for water treatment especially using nanosized metal oxides as catalysts [12][13][14][15][16][17][18].…”
