“…Therefore it is necessary to take into account the dilution of the feedstock by hydrogencontaining gas in hydrodewaxing process mathematical model, which was done by the authors in [13,14]. The values of the pre-exponential factors in the Arrhenius equation were estimated by solving the inverse kinetic problem, which lies in the selection of the values of the kinetic parameters which ensuring minimum deviations between the calculated and experimental parameters.…”

Abstract. The aim of the work is to carry out the research of diesel fuels dewaxing process. The study is based on fundamental mathematical model of the process, which takes into account poisoning of the metal centers and acid sites due to coking. Formed mathematical model was implemented for monitoring calculation with the aim of improving the efficiency of dewaxing catalyst loaded to the industrial reactor. Three operational modes were recorded for dewaxing unit. Optimization calculation of temperature at summer mode revealed that temperature in the dewaxing reactor could be decreased to 325°C without fuel quality loss.

“…The calculation results of the average values of the thermodynamic parameters of the most probable catalytic cracking reactions at the process conditions (T = 504 ° C, P = 0.108 MPa).are presented in table 3. The values of Gibbs energy reaction (ΔG) characterizes the probability of reaction and it value is necessary for formalization of the hydrocarbon chemical transformations scheme, which will be the foundation to the catalytic cracking kinetic model.…”

Abstract. The issue of improving the energy and resource efficiency of advanced petroleum processing can be solved by the development of adequate mathematical model based on physical and chemical regularities of process reactions with a high predictive potential in the advanced petroleum refining. In this work, the development of formalized hydrocarbon conversion scheme of catalytic cracking was performed using thermodynamic parameters of reaction defined by the Density Functional Theory. The list of reaction was compiled according to the results of feedstock structural-group composition definition, which was done by the n-d-m-method, the Hazelvuda method, qualitative composition of feedstock defined by gas chromatography-mass spectrometry and individual composition of catalytic cracking gasoline fraction. Formalized hydrocarbon conversion scheme of catalytic cracking will become the basis for the development of the catalytic cracking kinetic model. IntroductionAt the present stage of fuel chemical technology development the advanced petroleum refining processes are the most significant for refining, because the industrial sector is focused on the efficient use of natural fuel-power resources and the demand in fuel is increasing every year.Currently, the construction of modern technologies for advanced petroleum processing such as hydrocracking, catalytic cracking, hydrotreating of heavy hydrocarbon fractions, hydrodewaxing and hydroisomerization is organized at the major refinery plants. Modernization of the refinery industry is principally connected with the aim to create a competitive refining and petrochemical sector, corresponding the high level of modern foreign refineries (oil refining depth -85-95%).Advanced petroleum processing is aimed to the production of light hydrocarbon fractions (mainly gasoline and diesel fractions) from the heavy fraction of petroleum feedstock.Exploitation of advanced petroleum processing units in the energy and resource-efficient modes should be carried out with the application of the mathematical models which are based on the hydrocarbon conversion mechanism reflecting the physical and chemical essence of process [1,2].It is important to take into account factors that influence the quality and quantity of production (multi-component of feedstock, catalyst types, process conditions, associativity of flowsheet devices and others.) during the development of mathematical model of the reactor. In addition, in petroleum fractions with boiling point above 200 °C the cyclic hydrocarbons are of mixed (hybrid) nature. Usually cyclic hydrocarbons contain the side paraffinic chains and, simultaneously, a part of naphthenic and aromatic rings.
