“…However, after oil bleaching, the presence of oil residual and solvent-rich components greatly increases the potential risk of spontaneous combustion of the spent bleaching earth powders, which is a fire hazard [7]. Proceeding from an inexpensive aspect, most of the spent bleaching earth powders are disposed of in landfills without further treatment or oil recovery, causing contamination of the soil and groundwater through environmental degradation and damage to living organisms [1,7,8]. In addition, the production of disposable bleaching earth usually requires chemical modifications, which may generate massive contaminants during production [6].…”

Novel hierarchical metal-organic framework/chitosan aerogel composites were developed for oil bleaching. UiO-66-COOH-type metal organic frameworks (Zr-MOFs) were synthesized and integrated onto a chitosan matrix with different contents and named MOF-aerogel-1 and MOF-aerogel-2. Due to the compatibility of chitosan, the carboxylic zirconium MOF-aerogels not only maintained the inherent chemical accessibility of UiO-66-COOH, but the unique crystallization and structural characteristics of these MOF nanoparticles were also preserved. Through 3-dimensional reconstructed images, aggregation of the UiO-66-COOH particles was observed in MOF-aerogel-1, while the MOF was homogeneously distributed on the surface of the chitosan lamellae in MOF-aerogel-2. All aerogels, with or without immobilized MOF nanoparticles, were capable of removing carotenoids during oil bleaching. MOF-aerogel-2 showed the most satisfying removal proportions of 26.6%, 36.5%, and 47.2% at 50 °C, 75 °C, and 100 °C, respectively, and its performance was very similar to that of commercial activated clay. The reuse performance of MOF-aerogel-2 was tested, and the results showed its exceptional sustainability for carotenoid removal. These findings suggested the effectiveness of the MOFaerogel for potential utilization in oil bleaching treatments.

“…To overcome the current challenges in the recycling of end-of-life tires, thermochemical recycling (i.e., pyrolysis) of the used tires is a promising option. The pyrolysis process converts non-recyclable polymers such as rubbers to valuable products (Abbas-Abadi et al, 2020, 2021bSeifali Abbas-Abadi and Nekoomanesh Haghighi, 2017). Several studies have been performed on tire pyrolysis (thermal, catalytic) (Chao et al, 2020;Taleb et al, 2020), degradation mechanisms (Li, D. et al, 2020), optimum process conditions (temperature (Nisar et al, 2018), heating rate (Wang et al, 2020), residence time (Ma et al, 2020), catalysts (Miandad et al, 2018), carrier gas (Kaminsky et al, 2009)), and structural parameters (Campuzano et al, 2021), as well as pyrolysis reactors (Campuzano et al, 2020;Xu et al, 2021).…”
