Development and application of LY-9302 type reformer prehydrogenation catalyst
The LY-9302 type reformer prehydrogenation catalyst is developed and applied in reformer prehydrogenation unit to replace the imported S-12 type catalyst. The result shows that under the conditions of reaction temperature of 295～308℃, pressure of 2.8～2.9MPa, the content of S≤346×10 -6 and N≤3.1×10 -6 in feedstock, volume space velocity of 4.4～7.0h -1 , and the hydrogen/oil volume ratio of 88.7～117, the contents of S and N in the prehydrogenation refining oil is lower than 0.5×10 -6 , the liquid yield of refining oil is higher than 97%, and can satisfy the production demand. Comparing with S-12 type catalyst, the activity of hydrogen desulfurization and denitrogenation of LY-9302 type catalyst is higher, the selectivity and life are corresponded. The LY-9302 type catalyst can replace the S-12 type catalyst.
