“…Table 4 shows these parameters for the power-law models. According to Cheng et al (1986) and Ali (2012), the order of reaction with respect to styrene is 1, corroborating the hypothesis of the PL_β model, whereas Tukac et al (2007) estimated an order of 0.5 for styrene, ratifying the PL_αβ model. However, Jackson and Shaw (1995) estimated zero order of reaction with respect to styrene, suggesting that Langmuir-Hinshelwood models are plausible options to represent the reaction rate.…”

“…In both power-law models, the order of reaction with respect to hydrogen of 0.7 was close to the value of 0.6 estimated by Vale (2013), and the first order reaction assumed by Cheng et al (1986) and estimated by Tukac et al (2007). Nijhuis et al (2003) also observed a first order with respect to hydrogen for pressures below 20 bar; with higher hydrogen pressures, the reaction rate stabilized, suggesting the viability of Langmuir-Hinshelwood models.…”

“…Contudo, alguns autores estudaram a operação periódica em reatores químicos onde observaram que a modulação das condições dos reagentes pode melhorar o rendimento do reator (Silveston e Hanika, 2004;Lange et al, 1999;Rouge et al, 2001;Tukac et al, 2007). De acordo com Silveston e Hanika (2004), a operação periódica em reatores trifásicos pode mudar a seletividade e aumentar tanto a conversão quanto o rendimento.…”
