ZEOLITE-CONTAINING CATALYST Zhuragat G. Research supervisor: C.C.S., associate professor Omarova A.A . Al-Farabi Kazakh National University, Almaty, Kazakhstan Oil and its products are the main raw materials in energy production, its global economic and political value has increased. The presence of oil reserves in the state, the ability to export oil and petroleum products, allows the state to achieve great success in economic and social prosperity. The depletion of natural resources and high requirements for the quality of motor fuels due to the constant tightening of environmental requirements by the the Global Community and Organizations came to the international treaty such as Paris Agreement. This leads to the need for deep hydrotreating and further improvement of fuel quality. Upgrading can be made by designing and developing new catalysts with higher activity and selectivity[1-3]. Kazakhstan has large reserves oil with different values of the sulfur and paraffin contents. It complicates processing methods of the oil and affects to the cost and quality of oil and its products. Currently, the technologies of Catalyst and hydro-treatment processes around the world do not meet the requirements for the quality of motor fuel produced. For instance, the transition to new technologies requires large investments, oil production plants in the United States and a number of other countries are closing. To solve these problems, it is necessary to create new single-stage Hydro-treatment technologies based on a high-performance multifunctional catalyst. Single-stage Hydro-treatment of gasoline fractions allows you to simplify refinery models, produce low-carbon motor fuel, which is cheaper in cost, but meets Euro-4, Euro-5 standards in quality, and improve the environmental situation. In this thesis the influence of temperature on the processing process of straight run gasoline under conditions P=4.0 MPA, V=2H-1 on the catalyst MSK-1 (COO-MoO3-SKM(rare earth metals)-P2O5-ZSM-Al2O3) would be discussed .Based on the results of the experiment on the basis of one catalyst discussion would be held, because the general trend of other catalysts is the same. According to the results of the experiment, when the temperature rises from 320° C to 400 ° C, the content of aromatic hydrocarbons decreases from 50.3% to 8.3% for straight-run gasoline, the yield of naphthenic hydrocarbons-from 31.4% to 19.1%. The content of olefins has not changed, and does not depend on the temperature of the process and is 4-4.9%. The liquid phase yield ranges from 96.0 to 60.6% in for straight-run gasoline, with a temperature increase from 320 to 400 ° C. The octane number of gasoline of direct distillation up to 400 ° C is a maximum of 92.8 (Z.D.) and 73.5 (M.D.) (Table 2). Concluding the results of the experiment, the transition to a single-stage process based on a multifunctional catalyst, simplifying the structure of petroleum products by removing unnecessary steps from the process, reducing the cost of motor fuel and increasing the efficiency of oil refining production. жүктеу/скачать 2,6 Mb.
