“…The high contents of Portlandite and calcite may be the result of carbonation and/or hydroxylation of the combustion product, CaO, with ambient moisture and CO 2 in the atmosphere to form a permanent polymorph of them. calcite and Portlandite, respectively. ,, These compounds are the primary components that make up basic catalysts, which can be detected in XRD analysis. With the exception of portlandite and calcite phases, other elements known with XRF were detected at nonperfect peaks with a very low value of FOM, which may be attributable to their amorphous nature or quantitative insensitivity of the XRD machine as proved in the software.…”

“…Similarly, the bending stretching mode of the C−O bond symmetrically within calcareous compounds has been identified to exhibit both out-of-plane as well as in-plane vibrations at 872 and 711 cm −1 , respectively; 943 cm −1 is the distinctive band of Si−O bond. 8,10,32,33,38,39 All of the aforementioned compounds were prettily identified with XRF and XRD analysis. Moreover, the impregnation effects of the catalyst are observed around 2323 cm −1 enabling the evolution of a new, substantial O−H binding that remained stable through the conditions of calcination because of the strong chemical attachment properties on the RC-ITB catalyst, while elimination could be possible on the RC one due to the physisorbed nature.…”

Industrial and academic societies have been bothered with the generation and subsequent management of residues settled out from household bleach, due to its corrosive properties. Therefore, the aim of this research was to introduce a NaOH-impregnated calcium-based solid catalyst from the aforementioned sediments for waste cooking oil transesterification. To prepare the catalyst (RC-ITB), the wet impregnation technique was followed and successfully characterized via X-ray diffraction (XRD), X-ray fluorescence(XRF), differential scanning calorimetry (DSC), Brunauer–Emmett–Teller (BET), Fourier transform infrared (FT-IR), and scanning electron microscopy (SEM) methods. The study findings suggested that RC-ITB has a BET surface area of 9.312 m2 g–1 and is largely made up of calcium with its compound forms such as carbonates, hydroxides, and oxides. The evaluation of pH values verified that RC-ITB is more alkaline (i.e., pH = 12.65) relative to its precursor RC (pH = 10.66), largely attributable to OH impregnation. To study the catalytic performance, three numeric factors with three levels of treatment were used, and their influences were analyzed through a response surface approach. Accordingly, the optimal yield of biodiesel was found to be 80.04% at a reaction temperature of 61 ± 2 °C, catalyst weight of 6.33 wt %, and a molar ratio of 23.94. Moreover, FTIR analysis verified that the glycerol part of triglycerides had been replaced with a methoxyl unit. Also, the fuel quality parameters of the FAME product were examined, including density, kinematic viscosity, acid value, density, cetane number, cloud point, saponification value, and pour point; all of these values fall within the ASTM D6751-accepted limits. Thus, the findings showed that the sediments of household bleach production could be a candidate source to explore heterogeneous basic catalysts.

The high cost of commercial catalysts has hampered the commercialization and cost-effective production of renewable diesel in recent times. This research investigates the effect of silica (SiO2) reinforcement on bio-based thermal power plant fly ash (BBTPPFS) for hydrogenation. The BBTPPFS and the SIO2 were pulverized, calcinated, and subjected to various characterization processes. The value of micropore volume, surface area, and external surface area of sample due to the reinforcement by SiO2. These results show that the addition of SiO2 to BBTPPFS improved the potential of the BBTPPFS as a heterogeneous catalyst for hydrogenation.

“…Fly ash is used as a catalyst for catalytic cracking or catalytic upgrading of waste plastics, which can realize the comprehensive recycling of waste plastics and fly ash. [64,65] Gaurh et al [66] used fly ash (FA) as raw material to synthesize catalysts (FA, FA-600, FA-700, FA-800 and FA-900) at different temperatures. The catalyst effectively produced valuable aromatic hydrocarbons such as benzene, toluene, ethyl benzene and xylene (BTEX) from waste PE.…”

Waste plastics (e.g., polyethylene, polyvinyl chloride, polypropylene, polystyrene) and petroleum sludge (i.e., main residual from the petroleum industry) pose a severe threat to the environment and human health. These materials are basically nonbiodegradable, and it is difficult to realize the recycling of them and resources via traditional treatment methods. Catalytic pyrolysis as a new recycling treatment method has the characteristics of high efficiency, environmentally benign, no secondary pollution and high product utilization value. This paper mainly reviews the research progress of catalysts used in the catalytic pyrolysis of waste plastics and petroleum sludge. They include molecular sieves, transition metals, metal oxides, clays and activated carbons used for the recycling of plastic, and molecular sieves and M-series catalyst (M=Al, Fe, Ca, Na, K) for treating petroleum sludge. The mechanism of catalytic pyrolysis is also elucidated in this paper. In addition, the challenges faced by catalytic pyrolysis of waste polymers and the future development prospects are also presented.
