“…The findings indicated that a standard carbonization temperature of 700 • C and subsequent activation in a water vapor environment at 800 • C are required for pet coke. These ideal thermal treatment conditions can be considered a standard for producing granulated AC [99]. Heat treatment was also carried out to obtain oxygen-rich AC using pet coke as a starting material.…”

This comprehensive review addresses the need for sustainable and efficient energy storage technologies against escalating global energy demand and environmental concerns. It explores the innovative utilization of waste materials from oil refineries and coal processing industries as precursors for carbon-based electrodes in next-generation energy storage systems, including batteries and supercapacitors. These waste-derived carbon materials, such as semi-coke, coal gasification fine ash, coal tar pitch, petroleum coke, and petroleum vacuum residue, offer a promising alternative to conventional electrode materials. They present an optimal balance of high carbon content and enhanced electrochemical properties while promoting environmental sustainability through effectively repurposing waste materials from coal and hydrocarbon industries. This review systematically examines recent advancements in fabricating and applying waste-derived carbon-based electrodes. It delves into the methodologies for converting industrial by-products into high-quality carbon electrodes, with a particular emphasis on carbonization and activation processes tailored to enhance the electrochemical performance of the derived materials. Key findings indicate that while higher carbonization temperatures may impede the development of a porous structure, using KOH as an activating agent has proven effective in developing mesoporous structures conducive to ion transport and storage. Moreover, incorporating heteroatom doping (with elements such as sulfur, potassium, and nitrogen) has shown promise in enhancing surface interactions and facilitating the diffusion process through increased availability of active sites, thereby demonstrating the potential for improved storage capabilities. The electrochemical performance of these waste-derived carbon materials is evaluated across various configurations and electrolytes. Challenges and future directions are identified, highlighting the need for a deeper understanding of the microstructural characteristics that influence electrochemical performance and advocating for interdisciplinary research to achieve precise control over material properties. This review contributes to advancing electrode material technology and promotes environmental sustainability by repurposing industrial waste into valuable resources for energy storage. It underscores the potential of waste-derived carbon materials in sustainably meeting global energy storage demands.

Currently, the processes of the oil industry are focused on deepening oil refining. One of the ways to deepen oil refining is to obtain petroleum cokes at delayed coking plants. At the moment, the total productivity of delayed coking plants is increasing, while the output of petroleum coke with a high sulfur content is also growing, which does not allow it to be used in a typical consumption industry – the metallurgical industry. In this regard, researchers are actively exploring the possibility of qualified alternative use of petroleum coke. One of the promising directions is the use of petroleum coke as a raw material for the production of activated carbons, which will significantly expand the raw material base of their production. In this paper, studies have been conducted on the possibility of obtaining crushed activated carbons based on KES grade petroleum coke. During the experiments, samples of crushed activated carbons were obtained by single- and double-stage heat treatment (carbonation in an inert atmosphere and activation in an environment of superheated water vapor), and the characteristics of their porous structure were determined. The research results have shown that activated carbon obtained by two-stage heat treatment has a sufficiently high specific surface area (446 m2/g) and a maximum volume of sorption space (0.264 cm3/g). Thus, the proposed method of processing petroleum coke obtained by delayed coking into activated carbon can serve as one of the ways to expand its qualified use, and also opens up alternative raw material opportunities in the technology of activated carbon production.

This study aimed to create activated carbon thin film (ACTF) as a hybrid nanocarbon via a simple and efficient method through a single-step mixing process using thermal functionalization techniques. TEM, BET, BJH, FTIR, XRD, and TGA analyses were used to investigate the prepared ACTF. The results exhibited that ACTF has a porous structure with a high surface area of 318 m2/g and important functional groups, which are considered significant adsorption sites. The adsorption performance of ACTF for phenol and p-nitrophenol (PNP) removal from aqueous solutions using batch adsorption mode was studied. Evaluations were conducted on experimental factors influencing the adsorption process, such as pH, initial phenol and PNP concentrations, adsorbent dose, contact time, and temperature. Under the optimized conditions, the phenol and PNP were removed with a maximum efficiency of 89.98% and 92.5%, respectively. The results of linear and nonlinear isotherms and kinetic models of phenol and PNP showed that both pollutants were well fitted with the Freundlich model (R2 = 0.99, χ2 = 0.13, RMSE = 1.6), (R2 = 0.99, χ2 = 0.42, RMSE = 2.8), and the pseudo-second-order model (R2 = 0.999, χ2 = 0.03, RMSE = 0.31), (R2 = 0.99, χ2 = 0.01, RMSE = 0.24), for phenol and PNP, respectively. According to the calculated thermodynamic results, the adsorption of phenol and p-nitrophenol onto the ACTF surface was a spontaneous and exothermic reaction. The regeneration experiments showed that the spent ACTF could be reused up to the fifth cycle while maintaining noteworthy removal efficiency.
