“…It was determined that flow-through membrane reactors perform better due to the high contact efficiency between the propene, O 2 molecules, and catalytic active sites (Figure ii). This was further evidenced by Kajama et al, who also observed that the contactor flow-through membrane reactors were highly effective for this reaction.…”

“…In addition, a decrease in the average pore diameter was obtained which is possibly due to pore blockage caused by the metal platinum particles. However, no alteration was observed with respect to the pore volume on both the Al2O3 support and Pt/γ-Al2O3 membrane samples [36]. (Figure 3a).…”

Platinum-alumina (Pt/γ-Al2O3) catalytic membranes were obtained using the reservoir technique for the combustion of volatile organic compounds (VOCs). The membranes were characterized by scanning electron microscopy and energy dispersive X-ray analysis (SEM-EDXA) observation, Brunauer-Emmett-Teller (BET) measurement and gas permeation. Propane (C3H8) and n-butane (C4H10) combustion was obtained. Maximum VOC conversion for propane and n-butane of 93 and 48 (%) was achieved on 3.52wt% Pt catalyst at a temperature of 427 and 259 (0 C) and flow rates of between 185-222 and 295-379 (ml/min) without any changes in conversion. The combustion results of C3H8 and C4H10 corroborate with literature on Pt/γ-Al2O3 catalysts. The conversion was achieved using flow-through catalytic membrane reactor operating in the Knudsen flow regime.

“…Perovskite oxides have been extensively studied in the catalytic oxidation of VOCs and have shown high catalytic activity during the oxidation process [26,27]. LaFeO 3 is a typical perovskite that is widely used for catalytic oxidation [28][29][30][31] and gas and biosensors [32][33][34] due to its good catalytic activity and high stability. It is also used in solid oxide fuel cells [35] by virtue of its excellent catalytic activity, high electrical conductivity and oxygen mobility.…”

Porous LaFeO3 powders were produced by high-temperature calcination of LaFeO3 precursors obtained by hydrothermal treatment of corresponding nitrates in the presence of citric acid. Four LaFeO3 powders calcinated at different temperatures were mixed with appropriate amounts of kaolinite, carboxymethyl cellulose, glycerol and active carbon for the preparation of monolithic LaFeO3 by extrusion. Porous LaFeO3 powders were characterized using powder X-ray diffraction, scanning electron microscopy, nitrogen absorption/desorption and X-ray photoelectron spectroscopy. Among the four monolithic LaFeO3 catalysts, the catalyst calcinated at 700 °C showed the best catalytic activity for the catalytic oxidation of toluene at 36,000 mL/(g∙h), and the corresponding T10%, T50% and T90% was 76 °C, 253 °C and 420 °C, respectively. The catalytic performance is attributed to the larger specific surface area (23.41 m2/g), higher surface adsorption of oxygen concentration and larger Fe2+/Fe3+ ratio associated with LaFeO3 calcined at 700 °C.
