Although China has adopted the domestic gasoline standard as a reference, the quality of gasoline produced by domestic refineries is difficult to meet the standard requirements. There are two main reasons for this:

First, the raw materials are poor. The two major groups of Sinopec and PetroChina can basically represent domestic suppliers of refined oil. Among them, Sinopec processing crude oil mainly comes from high-sulfur medium-quality crude oil in the Middle East, such as Saudi Arabia, United Arab Emirates, Iran, etc.; PetroChina processing crude oil is mainly domestic high-sulfur medium crude oil, including Daqing Oilfield and Shengli Oilfield. More oil information oil information oil transfer technology, please pay attention to WeChat public number oil circle. The European refinery processing North Sea crude oil and the US WTI crude oil are all low-sulfur light sweet crude oil, which is easy to produce and process. The quality of gasoline produced by domestic enterprises is inevitably inferior.

Second, the level of production technology is not high. At present, China’s gasoline production process is mainly based on catalytic cracking, while catalytic gasoline has relatively low octane number, high sulfur content and high olefin content. In Europe and America, reforming process is adopted, and the quality of oil is high. In addition, China’s refineries also have a certain gap in foreign countries in terms of product desulfurization and refining.
