摘要： The invention relates to a process to improve the stability of a catalyst to be used for lowering the cloud or turbidity point and the filterability limit temperature of gas-oils.The catalyst is formed of a composite system constituting 5 to 90% of a hydrodesulfuration type catalyst A and 95 to 10% of a hydroconversion type catalyst B, these two catalysts being either mixed or superposed, in which case catalyst A forms the top of the catalytic bed.
