In order to enhance the four‐way purification performance of PM, NOx, CO and HC emitted by automobile exhausts over woody La0.8Ce0.2Fe0.3Co0.7O3 perovskite‐type catalysts. First, the woody La0.8Ce0.2Fe0.3Co0.7O3 perovskite‐type catalysts were modified by nonthermal plasma (NTP). The physicochemical properties of the catalyst surface were characterized utilizing x‐ray diffractometer, Fourier‐transform infrared spectroscopy, x‐ray photoelectronic spectroscopy, scanning electron microscope and Brunauer–Emmett–Teller to analyze the effect of NTP on surface character of the catalyst samples. Second, NTP was combined with woody La0.8Ce0.2Fe0.3Co0.7O3 perovskite‐type catalysts to form in‐plasma catalysis purification (IPCP) systems. Finally, the four‐way purification performance of perovskite‐type catalysts were evaluated in the presence and absence of the plasma by simulation test bench. The results showed that NTP can enhance the four‐way purification performance for PM, NOx, CO and HC emitted by automobile exhausts over woody La0.8Ce0.2Fe0.3Co0.7O3 perovskite‐type catalysts. NTP can increase the specific surface area and porosity. When the input voltage, frequency and filling rate of IPCP systems are 15 kV, 15 Hz and 0.3, respectively, the maximum purification efficiency for PM, NOx, CO and HC are about 96%, 95%, 95%, and 84%. Moreover, four‐way purification mechanism of IPCP was deduced according to the experimental results.

“…The ex-situ approach allows greater control over product selectivity (notably to desirable aromatics), through independent optimization of the pyrolyszer and catalytic reactor operating parameters but requires a higher capital investment. La(Co 0.5 Mn 0.5 )O 3 , La(Mn 0.5 Ni 0.5 )O 3 , and La(Co 0.5 Ni 0.5 )O 3 perovskite oxides have been used for catalytic pyrolysis, 314 lowering the activation energy, and hence reaction temperature, for the decomposition of date seed and mandarin peel, and improving selectivity to the desired bio-oil fuel precursor. Partial substitution of the B′ site enhanced catalytic activity, with La(Mn 0.5 Ni 0.5 )O 3 delivering the greatest bio-oil yields of 28% and 26% from dates and mandarin, respectively.…”

Perovskite Catalysts for Biomass Valorization

Biomass is a widely used renewable energy source, whose uptake is growing due to concerns about the impact of anthropogenic fossil fuel combustion on climate change. Waste biomass-derived fuels and chemicals offer a partial solution to reducing global reliance on fossil fuels in pursuit of Net Zero 2050 CO2 emissions, in concert with environmental, health, and economic benefits. Biorefineries aim to convert biomass resources such as forestry and agricultural waste into diverse product streams, akin to the processing of nonrenewable fossil fuels by petrochemical refineries. However, realizing this ambition requires design of hydrothermally stable catalysts with tunable redox properties and acid–base character to promote molecular deoxygenation or the interconversion of oxygen functionalities. Perovskite oxides of general formula ABO3 (where A = rare or alkaline earth cations and B = transition metal cations) exhibit structural flexibility and diverse surface chemistry; ∼90% of all metals can be introduced to perovskite oxides. Here, we review recent developments in the use of perovskite oxide catalysts for biomass valorization, focusing on structure–reactivity relationships in hydroprocessing, oxidation, steam reforming, and acid–base reactions. Prospects and challenges for the broader application of perovskite oxide catalysts to biomass valorization are also highlighted.

“…Plum waste generated after juice production corresponds to approximately 15% of the total production. The pyrolysis of several fruit wastes such as cherry stones [17], banana empty fruit bunch and delonix regia fruit pod [18], date seed and mandarin peel [19], and fruit pulps [20][21][22] has been studied so far to produce bio-oil or carbonaceous solids. However, so far, no detailed data have been collected on plum stone pyrolysis and catalytic pyrolysis.…”

Plum stone stands out as an alternative biomass source in terms of obtaining fuel and chemicals with or without catalysts under different conditions. Under variable heating rates (10, 50, and 100 °C min−1) and pyrolysis temperatures (400, 450, 500, 550, and 600 °C), plum stone was pyrolyzed at a constant rate in a constant sweep gas flow (100 cm3 min−1) in a tubular fixed-bed reactor. According to the results, an oil yield reaching a maximum of 45% was obtained at a heating rate of 100 °C min−1 and pyrolysis temperature of 550 °C in the non-catalytic procedure. The catalytic pyrolysis was carried out with two selected commercial catalysts, namely ZSM-5 and PURMOL-CTX and clinoptilolite (natural zeolite, NZ) under optimum conditions with a catalyst ratio of 10% of the raw material. With the addition of catalyst, the quantity and quality of bio-oil increased, including calorific capacity, the removal of oxygenated groups, and hydrocarbon distribution. In the presence of catalysts, an increase was observed in terms of desirable products such as phenol, alkene, and alkane, and a decrease in terms of undesirable products such as acids. Considering and evaluating all the results, the use of zeolite materials as catalysts in pyrolysis is a recommended option for obtaining enhanced chemicals and fuels.
