Abstract

The effects of concentrations of sulfur, nitrogen, bi-(BA) and monoaromatics (MA) in heavy atmospheric gas oil(HAGO), H2S and ammonia in gas phase on HDS rate at deep desulfuriation stage (Sin 1110-60 ppm) were studied with Co-Mo-Al and Ni-W-Si catalysts using HAGO with FBP of 390°C and initial sulfur content of 1.24 wt.%. The complete elimination of hydrogen sulfide, ammonia, polyaromatics and partial elimination of monoaromatics prior to the deep desulfurization stage increases the overall rate of deep HDS by a factor of about six.
