Basic components of gasoline in various countries
Thread Content
The composition of gasoline in the United States is roughly one-third catalytic cracking gasoline, one-third catalytic reforming gasoline, and one-third other high-octane blending components. 27% in Western European catalytic cracking gasoline, 47% in catalytic reforming gasoline; the remainder consists mainly of other high-octane components. In China, catalytic cracking gasoline accounts for as much as 75% of total gasoline consumption, while the proportions of reformed gasoline, alkylated oil, MTBE, etc. are very low. This difference in the composition of gasoline results in a significant gap in gasoline quality between China and other countries.
The main problems with the quality of automotive gasoline in our country at present are high levels of olefins and sulfur.
Therefore, to change the current situation, developing friendly full hydrogenation processes is the way forward; processes similar to coking and catalytic processes will be further improved to reduce environmental pollution.
