“…In particular, the dehydrogenation of ethylbenzene to produce styrene has motivated many studies, due to the great economic importance of this monomer, as an intermediary in the production of several plastics, including polystyrene, synthetic rubber, copolymeric resins, unsaturated polyesters and elastomers. These derivatives, in turn, are used in countless finished products, such as packaging, parts for appliances, telephones, car accessories, toys, disposable materials and other products, besides their use in the production of biocomposites (Oliveira, de, Souza, Pereira Neto & Lima, 2020) and as environmental catalysts (Silva, et al, 2020). The styrene monomer is one of the main chemical intermediates and its production and importance is only lower than that of polyethylene (Addiego, Liu & Borger, 2001).…”
