Discussion on the Improvement of Cleaning Gasoline and Diesel in China
QIAO Li (Research Institute of Petroleum Processing, Beijing 100083, China)
Automobile emission is one of major sources of air pollution.The main pollutants contained are carbon monoxide, hydrocarbons and oxides of nitrogen.New pollution control standard requires improvement both on automobiles and fuels. To efficiently control auto emission pollution, we can upgrade gasoline and diesel by various means such as removing lead in gasoline, reducing contents of benzene, aromatics, olefins and sulfur, lowering RVP and 90% point distillation, and adding oxygenates and cleaning dispersant additives. A series of technology reforms are needed in refineries to achieve this goal. Refineries must advanced on adjusting refining plant and constitutes of products. Cracking catalytic gasoline accounts for more than 80% of total gasoline in China. It's difficult to meet the demand of clean fuels. Referring to the experience of U.S.A and Europe, we must increase catalytic reforming plant, alkylation plant, isomerization plant and adjust structure of setting step by step. But we should consider carefully about MTBE issue.
