| Abstract: | The operation process of heavy C+9 cut pyrolysis in the first stage hydrogenation unit in Beijing Yansan Branch of Sinopec Catalyst Company under the condition of low pressure,low space velocity,high hydrogen/oil ratio,and high recycling ratio was introduced.Based on the condition change of feed properties,reaction temperatures and pressure drop of reactor inlet and outlet over YN-1 nickel based catalyst without regeneration,the change of bromine valence and diene contents of the first stage hydrogenation product were statistically analyzed.The commercial application results showed that YN-1 nickel based catalyst had excellent hydrogenation activity and stability during the long period operation. |
