“…For example, the total amount of coke in the catalysis is 34.92 % higher than the one, which could be observed during optimal operation. The most selectivity of the catalyst is achieved during the working on the optimal activity 14,15 . According to this, as a result of "Catalyst's Control" program application should be output product's increasing with constant level of productions' costs.…”

Catalytic reforming of naphtha is one of the most important processes for high octane gasoline manufacture and aromatic hydrocarbons production. The application of computer modelling system “Catalyst's Control” for monitoring of catalytic reforming unit of Achinsk oil-refinery is stated. The mathematical model-based system takes into account the physical and chemical mechanisms of hydrocarbon mixture conversion reaction as well as the catalyst deactivation. The models created can be used for optimization and prediction of operating parameters (octane number, reactors outlet temperature and yield) of the reforming process. It is shown, that the work on the optimal activity allows increasing product output with a constant level of production costs, and get the information about Pt-Re catalyst work efficiency

“…As is known, more than 90% of all investments in the field of catalysis are spent on resolving problems associated with the deactivation of catalysts, and about 50% of scientific developments are made in the study of coke formation mechanism by the example of individual coxogenic substances [3]. To a lesser extent, patterns of pressure and temperature influence on the formation of coke deposits in the course of processing of hydrocarbon materials of variable composition in industrial reactors have been studied [2,4]. The researchers of Tomsk Polytechnic University carried out work aimed at improving the efficiency of existing plants using computer simulation systems which are especially relevant for semi-regenerative processes where carbonization of catalysts does not determine the stationary state of the targeted chemical reforming reactions [4].…”

“…The use of the nonstationary kinetic model proved the feasibility of computer control over industrial processes CHEMICAL PROBLEMS 2020 no. 3 (18) where coke accumulation during operation of the plant at the current and optimal activity is significantly different for different catalysts [4,5]. When creating the algorithms, the authors took into account the balance of acid and metal functions of Pt-containing catalysts according to the monitoring of the reforming process in industrial reactors of a particular type [6,7].…”

This research pursues an objective to explore the composition and physicochemical characteristics of the domestic adsorbent obtained through processing alumina waste from the local industry upon completion of testing in the course of purification of hydrogen-containing gas from chlorine-containing compounds. Also, changes in the quantitative ratio of the main chemisorption products of harmful impurities (NaCl, AlCl 3 , AlCl 3 .6H 2 O and AlxCly (OH) z .nH 2 O) depending on modifiers of various nature were determined. The NaCl content in the adsorbents used rose symbatically in the concentration of main centers due to surface aluminates and sodium carboaluminate in the initial samples. The amount of coke-like deposits with a high hydrogen content С n Н 1.75-1.8n satisfactorily correlated with the concentration of strong secondary acid sites arising from the formation of aluminum chlorides and hydroxychlorides. The accumulation of coke-like deposits with graphitic structure during the testing of adsorbents under industrial conditions for gas purification in the regeneration of catalyst reforming did not exceed 1.5% of the mass.
