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 proper-ties,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 cat-alyst had excellent hydrogenation activity and stability dUring the long period operation.
