TORH-1 Reforming generation oil hydrogenation deolefin catalyst and process technology
TORH-1 Reforming generation oil hydrogenation deolefin catalyst adopts a new type of alumina with a special pore structure as the carrier. The carrier has a high specific surface area and a high pore volume, and the proportion of 4-10nm pores is more than 30% higher than that of conventional SB alumina. The special pore structure is conducive to reaction mass transfer and heat transfer, and it is easy to burn and regenerate. The catalyst does not require additional pre-sulfurization at the initial stage of operation, the startup process is simple, time-saving, and environmentally friendly.
The preparation method of TORH-1 catalyst is a co-impregnation method, which optimizes the introduction of active components of the catalyst, and uses competitive adsorbents to achieve uniform dispersion of active components Pt and Pd, so that the active components can function more effectively. TORH-1 catalyst Appearance is a cylindrical bar with a diameter of 1.2~1.8mm and a heap ratio of 0.60±0.05g/mL.
Using Reforming generation oil with a bromine index of 1500~4600 mgBr/100g as the reaction raw material, under the conditions of reaction pressure of 1.7~2.0MPa, volumetric space velocity of 12.5h-1, and hydrogen-oil volume ratio of 250:1, the catalyst's deolefin conversion rate Up to 99.9%, with high deolefin activity, low aromatic loss and less than 0.5w%. TORH-1 catalyst has good activity, selectivity and stability.
