“…This provided a detailed solution to the hydrocracking of heavy oils. The authors also studied pressure and temperature effects on the hydrocracking of heavy crude oil (Elizalde et al 2010, Mederos et al 2012. This method was also used to investigate the hydrotreatment modeling of a variety of vacuum gas oil (VGO) feedstocks (Becker et al 2015) and to investigate catalyst deactivation during the hyrdocracking of atmospheric residue (Elizalde and Ancheyta 2014).…”

AbstractKinetic predictions for complex reaction systems of hydrocarbons are theoretically and technologically crucial to the petrochemical industry. Among several proposed kinetic models, a lumping kinetic model is a comparatively simple and developed method wherein a complex system is lumped into several pseudo-components. To acquire more accurate mechanistic information, kinetic models at the mechanistic level are developed, such as single-event kinetic and structure-oriented models. However, the number of kinetic parameters increases exponentially in these methods. Lumping kinetic methods are then reexamined, and kinetic models, such as relumping single-event kinetic methods, bimolecular methods, and special pseudo-component methods, are proposed to simplify the reaction system. Many mathematical methods, such as annealing algorithm or artificial neural networks, have also been developed to solve these complex reaction problems. Although a number of complex intrinsic reaction studies have been introduced, the combination of excellent prediction performances and practical industrial applicability remains a central challenge facing this field. This situation motivated this study, to review the recent development of reaction prediction models and their application in industrial processes. Furthermore, the practical applications of these possible pathways of kinetic predictions for mechanistic studies are addressed.

“…Temperature and concentrations change only as a function of time and axial position in the bed. Hydrodesulfurization product H 2 S is reported to inhibit the reaction kinetics in the literature (Mederos et al, 2006(Mederos et al, , 2012Sau et al, 1997). However, since there is no way of independently verifying it in the plant, we have assumed that there is no H 2 S inhibition.…”

“…Results showed negligible radial effects and one-dimensional modeling was recommended. Mederos et al (2006) and Mederos et al (2012) developed a heterogeneous one-dimensional model that consisted of dynamic mass and energy balance equations for the liquid and solid phases. All the reactions of different sulfur compounds were lumped to a single HDS reaction.…”

“…Entre as abordagens de modelagem de reatores químicos envolvendo reações de hidrotratamento, as mais comuns são aquelas que fazem a análise baseada no modelo a parâmetros concentrados, geralmente desenvolvidos como modelos de reatores pseudohomogêneo e heterogêneo em estado estacionário, enquanto que estudos sobre modelagem e simulação transiente sejam com modelos de reatores pseudo-homogêneos ou heterogêneos são escassos [16].…”

“…Esse método consiste em transformar as EDPs em um conjunto de equações diferenciais ordinárias (EDO) de primeira ordem pela discretização das derivadas espaciais na direção axial usando expressão de diferença finita atrasada e mantendo as derivadas parciais no tempo sem discretizar [16].…”

Um modelo de reator heterogêneo unidimensional em regime transiente foi desenvolvido para simular um reator de leito gotejante aplicado à hidrodessulfurização de petróleo. O modelo incorpora a resistência à transferência de massa nas interfaces gás-líquido e líquido-sólido e uma expressão da taxa da reação baseada no modelo cinético do tipo Langmuir-Hinshelwood. Mediante estimativa de parâmetros, o modelo foi ajustado com base em dados experimentais de um reator em escala piloto e, então, validado sob diferentes condições de operação. Por fim, estudou-se tanto o efeito de inibição de H2S como também o efeito das condições operacionais sobre a conversão de HDS, tais como: pressão, temperatura, velocidade espacial horária líquida (LHSV).
