(2bu) MOFs-Derived Carbon (MDC) for Organic Chloride Removal in the Waste Plastic Pyrolysis Oil (WPPO) and Its Modeling Studies (Kinetic, equilibrium, and thermodynamic analysis)

Globally, plastic waste is pointed out as one of the new environmental problems, and the economical and efficient circular recycling of waste plastics is urgently required. Chemical recycling is positively considered in that it is possible to produce waste plastic pyrolysis oil (WPPO) and to recycle it as a chemical raw material. Therefore, the oil refining industry is actively engaged in the research and development of technologies for WPPO as a chemical raw material. However, organic chlorine compounds in WPPO are the cause of corrosion to process facilities and deterioration of WPPO quality, which are pointed out as one of the problems to be solved. In this study, the physical adsorption performance of organic chlorine compounds in WPPO was evaluated using porous carbon materials, MOFs-derived carbon (MDC). Parent MOFs are porous materials with high porosity, ultra-high surface area, and highly ordered structure and are concerned as feasible physical adsorbents. However, thermodynamic instability and low adsorption performance under humid conditions, and structural collapse have limited its industrial use. MDCs designed through the calcination and etching process utilize the structure and advantages of MOFs and solve the limited points of MOFs by converting them to carbon materials. As well, this designed meso- and macro pore size material and can selectively adsorb molecules with a large kinetic diameter. The physical adsorption performance of MDC in batch experiments was evaluated with model oils and actual WPPO. The experimental results indicated that the adsorption efficiency in model oils reaches up to 7.5 mg of organic chloride per g of adsorbent. The adsorption equilibrium analysis was evaluated with Langmuir, Freundlich, Temkin, and Dubinin-Radushkevich model to provide a better fit and the predication based on experimental data. The pseudo-first-order, pseudo-second-order, and intra-particle diffusion models were used as kinetic models in the experiment. According to above mentioned results reported that MDC would be an effective adsorbent for organic chloride components in WPPO.

Research Interests: I am mainly interested in porous materials, mainly metal organic frameworks (MOFs) and MOFs-derived carbon(MDC) and its application for gas separation and supercapacitor electrode. As well, I have been experience the process control and optimization with A.I so, also interested in this field. in particular, how AI is being applied to the chemical engineering industry and research fields.
