Abstract:
A process for the activation of a CoMo supported catalyst, comprising;a) heating the catalyst to a first temperature of about 350.degree. F. to about 450.degree. F. in a first effective amount of time, in the presence of hydrogen and hydrogen sulfide, and in the presence of a substantially olefin-free virgin naphtha at a firt effective pressure such that the environment is not a reducing environment;b) holding the catalyst at 350.degree. F. to about 450.degree. F. for a second effective amount of time so that at least 20% of the metals capable of sulfiding will sufide; andc) further healing said catalyst to a second temperature from about 550.degree. F. to 700.degree. F. in the presence of hydrogen and hydrogen sulfide and in the presence of the virgin naphtha and at a second effective pressure such that the environment is non-reducing, so that substantially all of the metals are sulfided in order to form an activated CoMo supported catalyst.
