| Summary: | Title screen The active development of the gas industry and an increase in the production and treatment of natural gas makes the problem of the effective use of the obtained by-products more and more actual, in particular, stable gas condensates, consisting mainly of hydrocarbons with5-7 carbon atoms. One of the promising areas for the use of stable gas condensates is their processing into components of motor fuels at low-tonnage autonomous units using zeolite catalysts. For the effective use of these technologies, a detailed study of the chemical conversion's directions, occurring on zeolite catalysts, is necessary. This research directly for the stable gas condensates is complicated by their diverse hydrocarbon composition. It is expedient to study the directions of chemical conversions for pure hydrocarbons, which make up most of the composition of stable gas condensates. In the work using a laboratory catalytic unit and the ZSM-5 structural type zeolite catalyst, the processing of pure npentane, n-hexane, and n-heptane was carried out. The process was carried out in the temperature range of 375-425oC with a step of 25oC, at a constant pressure of 0.35 MPa and a weight hour space velocity of 2 h-1. For the obtained products, the hydrocarbon composition was determined by the gas chromatography method. Based on the chromatographic analysis data, as well as theoretical aspects about the mechanism of the occurring chemical conversions on the ZSM-5 type zeolites, a list of theoretically possible reactions (865 reactions) was formed, for which thermodynamic parameters were calculated using the Gaussian software package under the conditions of the process realization. According to the results of thermodynamic analysis, it was found that under the process realization conditions on a zeolite catalyst, 777 reactions are thermodynamically possible. Based on the obtained results, a formalized scheme of C5-C7 hydrocarbons chemical conversions on ZSM-5 type zeolite catalyst has been developed. |
