ABSTRACT:
A hydrodesulfurization process for catalytically hydrosulfurizing highly aromatic feeds, especially catalytically cracked feeds such as light cycle oils from catalytic cracking processes and aromatic extracts, employs a hydrodesulfurization catalyst containing zeolite beta. The zeolite beta based catalyst is more effective for effecting desulfurization than comparable amorphous catalysts or catalysts based on other large pore size zeolite and is capable of achieving a high degree of desulfurization at relatively low levels of conversion. The hydrodesulfurization catalyst comprises a transition metal hydrogenation component, preferably Co/Mo, on zeolite beta together with an inert matrix. The zeolite beta based catalyst may be mixed with amorphous catalyst such as Co/Mo/alumina. The low sulfur products are useful as blending components for road diesel fuels and other distillate fuels.
