Problems solved by technology

However, the asphalt quality indicators in foreign countries are quite different from those in my country. It is difficult for asphalt products produced by using our traditional petroleum refining raw materials, formulas and processes to meet the quality standards of foreign asphalt.
[0003] For example, although the annual import demand of asphalt products in Australia is as high as one million tons, the asphalt products produced by my country's traditional petroleum refining raw materials and production process formula are mainly All of them meet the domestic asphalt product standards, but cannot meet the Australian asphalt quality index requirements, so the asphalt products produced cannot be exported to Australia, and an important asphalt export market has been lost in vain.

Abstract

The invention relates to an asphalt composition and a preparation method thereof. The asphalt composition is prepared from the following components in parts by weight: 69 to 83 parts of vacuum residue, 15 to 25 parts of heavy blended oil and 2 to 6 parts of light blended oil. The vacuum residual oil is produced by adopting specific and appropriate crude oil, a specific mixing ratio and a specific production process, and then the vacuum residual oil, the light blended oil and the heavy blended oil which meet specific requirements are stirred and blended according to a specified ratio to produce an asphalt product which meets the quality index requirements of Australian C-170 exported asphalt. The problem that asphalt products produced by adopting traditional petroleum refining raw materials, formulas and processes in China cannot reach export asphalt quality indexes is solved.

Description

technical field [0001] The invention belongs to the technical field of oil refining and chemical materials, and in particular relates to an asphalt composition and a preparation method thereof. Background technique [0002] In recent years, with the increasing oil refining capacity of domestic refineries, domestic asphalt production capacity has also increased rapidly, resulting in fierce competition in the domestic asphalt product market, especially homogeneous competition. In order to seek higher profits and sales, domestic oil refiners hope to produce asphalt products that meet foreign standards. However, there is a big difference between foreign asphalt quality indicators and our country's asphalt quality indicators. It is difficult for asphalt products produced by our traditional petroleum refining raw materials, formulas and processes to meet foreign asphalt quality standards. [0003] For example, although Australia’s annual import demand for asphalt products is as h...
