Abstract:
Heavy oil contains significant amounts of asphaltenes and resins, which makes its processing difficult and expensive. Traditional recycling methods such as thermal cracking and hydroconversion have low efficiency and high costs. In this regard, the development of new methods for refining heavy oil is an urgent task. The experiments were carried out at a temperature of 360 ° C and pressures up to 12 MPa in an atmosphere of superheated water vapor, including with the participation of various additives such as nickel oxide, monocarboxylic acid and polymer waste represented by high molecular weight polyolefins. It was found that during the degradation of heavy oil components on the surface of kaolin, the proportion of low-boiling compounds in the products increases, while the content of saturated and aromatic compounds, as well as resins and asphaltenes, decreases. The addition of monocarboxylic acid leads to an increase in the amount of alcohol-benzene resins and asphaltenes in cracking products. However, the addition of nickel oxide leads to an increase in the content of the nickel oxide fraction-200 ° C, which, in turn, leads to a decrease in viscosity and improves the mobility of liquid refining products. The combined cracking of heavy oil and polyolefins in the presence of kaolin and NiO leads to a significant increase in the content of benzene resins in the final product. The use of NiO and poly-α-olefins in the process of heavy oil refining makes it possible to obtain products with optimal rheological properties and a high yield of low-boiling fractions. The use of kaolin additives in the process of refining heavy oil through low-temperature cracking in an atmosphere of superheated steam is a promising area of research that may lead to the development of more efficient and environmentally friendly processing methods. The use of technologies for refining heavy petroleum raw materials in combination with poly-α-olefins makes it possible to expand the resource base of energy production, reduce dependence on the development of traditional hydrocarbon deposits and ensure the sustainable development of the petrochemical industry. Research in the field of refining heavy petroleum raw materials using polymer waste is a promising area that can lead to the development of new methods of oil refining and reduce the negative impact on the environment.
