In: Mathematical Modeling of Complex Reaction Systems in the Oil and Gas Industry Felix Lugo Jose Guillermo; Trejo Fernando; Ancheyta Juarez Jorge Discrete and continuous lumping models have been largely used to represent the reaction kinetics. Recently, the use of more complex and fundamental microkinetic models to simulate hydrocracking has increased the interest of the research community. A significant number of researchers determine the reaction order from the experimental findings or adopt values documented in the literature. The most inferred reaction order in the kinetic model for the hydrocracking of heavy oil using dispersed catalyst is the first order. The kinetic model based on SARA fractions (6-lump) was employed as well as the regular solution model to calculate the molar volumes and solubility parameters of SARA fractions, and then estimate the content of sediments during the hydrocracking of heavy oil using molybdenite as catalyst. One advantage of utilizing this kind of catalysts is that the mineral catalysts are cheaper compared with commercial catalyst used in other technologies. 2024-01-01T00:00:00Z https://dspace.kpfu.ru/xmlui/handle/net/186133 Catalytic In‐Situ Upgrading of Heavy and Extra‐Heavy Crude Oils. Chapter 7: Catalytic mechanism and kinetics Felix Lugo Jose Guillermo; Tirado Kota Aleksis; Al-Muntaser Ameen Ahmed; Varfolomeev Mikhail Alekseevich; Yuan Chengdong; Ancheyta Juarez Jorge This chapter focuses on the analysis of the different kinetic models reported in the literature for the in situ and ex situ upgrading of heavy and extra‐heavy crude oils using dispersed phase catalysts in a hydrogen and steam atmosphere. Hydrocracking reactions can be carried out by different mechanisms depending on the catalyst type: In the absence of a catalyst, hydropyrolysis reactions can be achieved at high pressures and temperatures. The information reported in the literature on kinetic models for hydrocracking of heavy fractions for in situ and ex situ applications includes the operating conditions, the type of feedstock and catalyst used to obtain the experimental data, the reactions schemes, and the lumps employed in each kinetic model. Currently, there are three main types of approaches to kinetic modeling: discrete lumps, continuous mixture, and single events. 2023-01-01T00:00:00Z https://dspace.kpfu.ru/xmlui/handle/net/186132 Catalytic In‐Situ Upgrading of Heavy and Extra‐Heavy Crude Oils. Chapter 1: Properties of Heavy and Extra‐Heavy Crude Oils Tirado Kota Aleksis; Felix Lugo Jose Guillermo; Trejo Fernando; Varfolomeev Mikhail Alekseevich; Yuan Chengdong; Nurgaliev Danis Karlovich; Sámano Vicente; Ancheyta Juarez Jorge This chapter presents the definition and classification of crude oils according to their constituents and describes the main properties used to characterize them. Basically, heavy crude oil has a much higher viscosity and density than conventional crude oil and generally has sulfur content higher than 2 wt%. The importance of certain physical properties has been highlighted for the classification of crude oil and complications of recovery from reservoirs. Physical properties such as density, viscosity, and pour point may vary widely in crude oils from different locations. Chemical properties are indispensable to know the quality of heavy or extra-heavy crude oils in order to evaluate the refining capacity likewise the type of products generated. Heavy crude oils from different origins present similar ranges of properties because they are characterized as viscous liquids with high content of heteroatoms providing low API gravity values. 2023-01-01T00:00:00Z https://dspace.kpfu.ru/xmlui/handle/net/186126 Математика.
