“…The results of FTIR analysis also revealed that the spectrum bands related to the oils were predominantly similar to both that of commercial diesel fuel [15] and those of other catalytic oils obtained from the catalytic cracking of the waste transformer oil with the use of a catalyst such as fly ash [6] and hydroquinone [16]. Furthermore, the comparative spectra belong to the oils of TO and BCTO was in agreement with those of other studies [17,18] containing the used engine oil and the spent lubricant engine oil with the use of a catalyst of coal ash and barium-strontium ferrite.…”

In this study, the main target was to obtain the liquid fuel‐like product from the catalytic cracking of the used transformer oil over bentonite as a low‐cost catalyst. For this aim, a series of cracking runs were performed under certain experimental conditions (450 °C cracking temperature, 10 °C/min of heating rate, and catalyst in the range of 0–8.0 wt %) in a fixed‐bed reactor. In catalytic cracking runs, the use of bentonite as a catalyst led to a considerable increase in yield of the cracking oil comparable to that of the noncatalytic oil. The highest yield value of 98.64 wt % was achieved at catalyst ratio of 4.0 wt %. Furthermore, the liquid product obtained in the highest yield was characterized by FTIR and GC–MS to evaluate its composition in terms of compound distributions as a comparison with the noncatalytic run. Also, its fuel properties such as cetane index, higher heating value, viscosity, density, water content, elemental content, and so forth were analyzed using standard test techniques. Based on these results obtained, the catalytic liquid product can be utilized to prepare liquid fuel blends with diesel for the diesel engines. © 2018 American Institute of Chemical Engineers Environ Prog, 38:e13080, 2019

“…The mechanisms of catalytic pyrolysis reactions including those use to eliminate some undesired compounds can be categorised into decarbonylation, decarboxylation, hydrocracking, hydrodeoxygenation and hydrogenation [7][8][9]. In recent studies, the catalysts that have been used in pyrolysis of waste engine oil include natural magnetite [10], barium-strontium ferrite [11], and zeolites [12]. Some of these studies focused on the influence of the catalysts on the production of diesel fractions while others focus on eliminating oxygenated compounds during the catalytic pyrolysis.…”

Cheap alumino-silicate materials such as clay materials and Y zeolite were selected for the catalytic pyrolysis of waste engine oil in a fixed bed reactor. A cheaper route of Y zeolite synthesis involving hydrothermal activation of the raw clay and hydrothermal synthesis was employed. X-ray diffraction technique, scanning electron microscopy, Fourier transform infra-red, and nitrogen desorption method were used to characterize the intermediate phases formed during the hydrothermal treatment of the clay and the synthesized Y zeolite during the hydrothermal processes. The chemical compositions of the liquid phase of catalytic pyrolysis were characterized by gas chromatography coupled with mass spectroscopy (GC-MS). The results revealed that the alkaline concentration strongly influenced the activation of the raw clay to obtain a useful phase for the subsequent synthesis of the Y zeolite. The synthesis improved the surface area from 29 m 2 /g for the clay to 745 m 2 /g for the zeolite. The catalytic pyrolysis resulted in diesel fractions of 64.8 and 54.7%, respectively for the Y zeolite and the clay. It was observed that the gasoline fractions increased to 20.5 and 19.1%, respectively for the zeolite and the clay. In the diesel fraction, the zeolite selectively improved the yield of the cyclo-alkanes which are key constituents in terms of the quality of diesel. Y zeolite was successfully derived from a natural clay and tested in the pyrolysis of waste engine oil. The synthesis route provides the opportunity to improve the catalytic property of the natural clay.
