“…The volatiles produced at this stage of thermal decomposition are the main sources for producing the pyrolytic liquid, which could be employed as a liquid fuel or a source for chemicals. Also, this stage is considered the active pyrolysis zone where the breaking of the weaker chemical bonds, intermolecular association, and side aliphatic chains occurs (Mohan et al, 2023). The third stage of thermal cracking occurred between 450 °C and 600 °C.…”

This research examines the catalytic performance of the catalyst developed from natural kaolin clay as a cheap catalyst for the thermal pyrolysis of date stones (DS). Firstly, the natural kaolin clay was acid-treated, followed by thermal activation at 600 °C for 2h to obtain the activated kaolin catalyst (AKC). Several techniques, like BET surface area, pore volume distribution, XRD, FESEM, and EDX, were utilized to identify the AKC. The BET surface area of the AKC was 119.49 m 2 /g, while its mean pore diameter amounted to 7.13 nm, indicating its mesoporosity. The catalytic activity of the AKC was examined via the thermal pyrolysis of DS. Effect of pyrolysis temperature (400-500 °C), catalyst loading (2.5-10.0 wt.%), pyrolysis period (30-120 min), and particle size of DS (0.25, 0.297, 0.4, 0.595, and 0.841 mm) on the pyrolysis products yield was investigated. The highest yield of pyrolytic liquid was produced at 425 °C for 1h using 2.5 wt.% of the AKC and 0.40 mm participle size of the feed. At these conditions, the pyrolytic liquid yield amounted to 60.64%. The analysis of the bio-oil (BO) fraction stripped from the pyrolytic liquid was achieved by FTIR spectroscopy, 1 H NMR spectroscopy, and GC-MS analysis, which indicated that the BO fraction was mainly composed of hydrocarbons and oxygenated hydrocarbons. Results from the GC-MS analysis exhibited that hydrocarbons (48.28%), oxygenates (41.42%), aromatics (10.44%), and nitrogenates (2.13%) were the main components of the BO. Alkenes and n-alkanes were the main constituents of the hydrocarbon part of the BO, while acids were the main component of oxygenates. Non-catalytic thermal cracking of DS at the optimal conditions exhibited a lower pyrolytic liquid yield than the catalytic process. Finally, the fuel properties of the BO produced via catalytic pyrolysis of DS were superior to those measured for that produced by the thermal pyrolysis process.

“…The third stage of thermal cracking occurred between 450 °C and 600 °C. This stage is usually slow and nearly steady, leaving behind a solid residue (biochar) (Mohan et al, 2023).…”

“…For example, Fadhil et al [9] explored the pyrolysis of DS under various conditions and established that 500 °C produced the best yield of BO. Mohan et al [10] also studied the pyrolysis of DS between 450 and 650 °C and concluded that 600 °C was the perfect temperature to produce the maximum yield of BO. On the other hand, cherry (Cerasus pseudocerasus G. DON) belongs to the Rosaceae family and the Prunoideae subfamily.…”

The essential objective of this work was to co‐pyrolyze a binary mixture of date and cherry seeds in a fixed‐bed reactor. The experimental variables influencing the output of products, such as the pyrolysis temperature, pyrolysis duration, particle size, and heating rate, were optimized. The maximum liquid fraction yield (55.55 % with a bio‐oil yield of 29.70 %) was attained at 500 °C for 60 min at a heating rate of 40 °C min−1 and a particle size of 0.25 mm. The Fourier transform infrared and gas chromatography‐mass spectrometry results revealed that the bio‐oil was predominantly composed of oxygenated hydrocarbons, primarily higher acids (52.05 %), esters (23.67 %), and phenols (13 %). Biochar was converted into activated carbon, which possessed a Brunaer‐Emmett‐Teller surface area of 1055.55 m2g−1. The amorphous structure of this carbon was confirmed by field emission‐scanning electron microscopy and X‐ray diffraction measurements.
