The ...Currently the catalytic reforming units are playing an increasingly important role for gasoline quality upgrading, increased production of high add-value aromatic compounds and supply of cheap hydrogen resources. The high proportion of FCC gasoline in China＇s automotive gasoline pool has led to a quite significant gap in gasoline quality as compared to the demand of World Fuel Charter and even to the new Chinese standards for unleaded automotive gasoline. According to the statistical data, the ratio of FCC naphtha in the gasoline pool is 35% in the US and 27% in EU, whereas that number is 75% in China＇s gasoline pool. The share of reformate and other high-quality gasoline components in the gasoline pool is 65% in the US and 73% in EU, whereas that number is merely 14% in China＇s gasoline pool along with a definite share of low-octane （straight-run） gasoline.展开更多

Since the environmental regulations are increasingly strin gent than ever, the production of clean automobile fuel is a vital target in China, especially after China has become a WTO member. However, the sulfur content in gasoline pool of China is still very high. Over 95% of the sulfur in gaso line pool comes from FCC naphtha. It is necessary to remove sulfur in FCC naphtha.展开更多
