Cracking of Heavy Hydrocarbons on the Shankanai Zeolite of Modified HPA for the Synthesis of Long-Chain α-Olefins

Abstract

The relevance of the subject of this scientific research is determined by the importance of the problem of using zeolites as catalysts of process of the heavy hydrocarbons’ cracking and studying the prospects for modifying heteropolyacids for the synthesis of long-chain α-olefins. The purpose of this scientific research is to study the prospects for the implementation of process of the heavy hydrocarbon cracking on Shankanai zeolite modified with heteropolyacids for the synthesis of long-chain olefins. The basis of the methodological approach in this research work is a combination of methods for system analysis of heavy hydrocarbon cracking processes using natural zeolites as catalysts for this process, with an analytical study of the prospects for implementing this process when modifying natural zeolites with heteropolyacids in order to synthesize α-olefins. In order to analyze the products of α-olefins, the method of gas-liquid chromatography and nuclear magnetic resonance spectrometry was used. The study is carried out under the condition of using the heavy hydrocarbon cracking process of natural zeolites of the Shankanai deposit as catalyst. The obtained results testify to the high efficiency of the practical application of the Shankanai deposit zeolites, upgraded with heteropolyacids when used as catalysts for the cracking of heavy hydrocarbons. The results obtained in the course of this scientific study, as well as conclusions formulated on their basis, are of significant practical importance for developers of chemical processes for oil cracking using natural zeolites modified with heteropolyacids as effective catalysts of this process, as well as for employees of oil refineries, whose professional duties include the quality control of the implementation of this process
