Catalyst performance evaluation:
The hydrodesulfurization performance of the comparative catalyst that Evaluation operation example 30-45 provides catalyst and comparative example 1-4 to provide, the results are shown in table 3.
Evaluating catalyst is to contain 4,6-dimethyl Dibenzothiophene (4,6-DMDBT) mixed solution of n-decane of 0.59 % by weight is raw material, in high-pressure micro-device (manufacturer: Beijing petrochemical industry information automation company, model: DADI) hydrodesulfurization activity of upper evaluate catalysts, become by catalyst breakage diameter to be 40-60 object particle, the loadings of catalyst is 0.15 gram.Before formal charging, first carry out presulfurization to catalyst with the cyclohexane containing 6 % by weight carbon disulfide respectively for sulfurized oil, the condition of presulfurization comprises: pressure is 4.14MPa, and temperature is 362 DEG C, time is 3.5 hours, and sulfurized oil feed rate is 0.2 ml/min.After sulfuration terminates, being cooled to reaction temperature is 280 DEG C, incision raw material.Reaction condition comprises: raw material feed rate is 0.2 ml/min, and pressure is 4.14MPa, and hydrogen to oil volume ratio is 900.React and sample in high-pressure separator exit after 3 hours.Gained sample Agilent6890N gas chromatograph is analyzed.Wherein, the hydrodesulfurization activity A of 4,6-DMDBT is calculated as follows:
A=ln[100/(100-X)],
In formula, X is the desulfurization degree (circular of X see " catalysis journal ", 2002,23(3) of 4,6-DMDBT: 271-275).
