Integrated mathematical modeling of catalytic cracking and zeolite-containing catalyst oxidative regeneration

Development of a Two‐Fluid Hydrodynamic Model for a Riser Reactor

“…In their work, in addition to coking, the authors describe other undesirable thermal cracking reactions that occur in a high-temperature section of a riser. Understanding of kinetics and thermodynamics of the industrial FCC process is also the focus of our recent works [4][5][6][7][8].…”

Heuristic Approach to Fuzzy Control of the Reforming Process in Refining and Geology

“…The catalytic reforming process is designed to produce high quality motor fuels -high-octane motor road vehicle gasoline, household gas and raw materials for petrochemical synthesis (Orazbayev, et al, 2022). A number of papers are known on the development and improvement of modeling and control approaches for the catalytic reforming process (Gumen, 2018, Orazbayev, et al, 2022, Panchenkov, 2018, Rubekin, 2018, Zhorov, 2017, Nazarova, et al, 2020. The following is implemented in the known systems of the catalytic reforming process control: optimal temperature distribution at the inlet of reforming reactors (Rakhmetov, et al, 2022); optimization of process modes of the reforming unit operation (Bekibayev, et al, 2022), catalyst quality control in the stabilization unit of the catalytic reforming unit (Dzhambekov, et al, 2022); situational control of the reforming process (Moldasheva, et al, 2022).…”

“…Since the problem of controlling the modes of the research object operation is characterized by multi-criteria and fuzziness of constraints the methods of modeling, multi-criteria optimization and decision making (Orazbayev et al, 2019:, Orazbayev, et al, 2022, Nazarova, et al, 2020, Bekibayev, et al, 2022, Makhazhanova, et al, 2020, Ospanov, et al, 2016, methods of fuzzy set theories and expert evaluations (Orazbayev, et al, 2022, Dzhambekov, et al, 2022, Orazbayev, et al, 2020:, Turekulova, et al, 2022, Jovanovic, et al, 2022, Gutsykova, et al, 2017 are applied for formulation and solution of this problem in a fuzzy environment.…”

“…Input, mode parameters used to control the reforming process have their boundary values, which are set by the technological regulations of the unit: ts solution, which would take into account and use the experience, knowledge and intuition of the DM, his rences when choosing any solutions. Since the problem of controlling the modes of the research object operation is characterized by multiria and fuzziness of constraints the methods of modeling, multi-criteria optimization and decision making zbayev et al, 2019:, Orazbayev, et al, 2022, Nazarova, et al, 2020, Bekibayev, et al, , Makhazhanova, et al, 2020, Ospanov, et al, 2016, methods of fuzzy set theories and expert evaluations zbayev, et al, 2022, Dzhambekov, et al, 2022, Orazbayev, et al, 2020:, Turekulova, et al, 2022, novic, et al, 2022, Gutsykova, et al, 2017 are applied for formulation and solution of this problem in a y environment.

“…The formalized problem of decision-making as to control of the reforming unit operation modes under conditions of multi-criteria and fuzziness can be written in the form of the following decision-making problem: take into account and use the experience, knowledge and intuition of the DM, his y solutions. ntrolling the modes of the research object operation is characterized by multiraints the methods of modeling, multi-criteria optimization and decision making , Orazbayev, et al, 2022, Nazarova, et al, 2020, Bekibayev, et al, 020, Ospanov, et al, 2016, methods of fuzzy set theories and expert evaluations zhambekov, et al, 2022, Orazbayev, et al, 2020:, Turekulova, et al, 2022, kova, et al, 2017 are applied for formulation and solution of this problem in a with the goal and objectives of the study the following basic findings were mulation of the problem of reforming process control based on the models of the itions of multi-criteria and fuzziness.…”
