摘要
With the standard of environmental protection becoming increasingly strict, it is required to remove sulfur and aromatics in diesel deeply. RIPP has developed several new hydrogenation catalysts and flexible processes, by means of which clean diesel fuel with low sulfur and low aromatic contents can be produced. From SRGO (Straight Run Gas Oil), which has an aromatic content of less than 30m%, a low sulfur and low aromatic diesel fuel or ultra-low sulfur diesel can be obtained by adopting a new process operating on highly active RN-series catalysts. From a feed with higher aromatic content (A=30～80m%),such as FCC-LCO, a low sulfur and low aromatic diesel fuel can be obtained by the SSHT, MHUG and DDA processes.
