Abstract: In order to adapt to the development trend of heavy and low quality wax oil feedstock and extend the operation period of the unit, Sinopec Dalian Research Insititute of Petroleum and Petrochemicals has developed FF-34 wax oil hydrotreating catalyst using special alumina carrier materials with large particle size, concentrated particle size distribution and high relative crystallinity as carrier material. FF-34 wax oil hydrotreating catalyst with larger pore size and pore volume and higher metal resistance and metal holding capacity is developed by using oil type Ⅱ active phase regulation technology. The commercial application of FF-34 catalyst in the 2.2 Mt/a wax oil hydrogenation unit of Sinopec Luoyang Company shows that under the conditions of inlet pressure of 10.0 MPa, space velocity of 1.00 h^-1, hydrogen oil volume ratio of 558, inlet reaction temperature of 334 ℃, the sulfur content of refined wax oil is 3 000 μg/g, the nitrogen content is 1 321 μg/g, and the chemical hydrogen consumption is 0.73%. The results show that FF-34 catalyst has good hydrodesulfurization and hydrodenitrogenation performance which is a suitable catalyst for refinery to process inferior wax oil at low hydrogen consumption.
