| Abstract: | A non–noble metal hydro-upgrading catalyst was prepared using modified zeolites as acidic component, and catalytic performance evaluation was also carried out between the hydro-upgrading catalyst and the reference catalyst, which is a commercial catalyst. The evaluation results revealed that under the pressure of 8.0 MPa, the diesel product yield of the hydro-upgrading catalyst was 98.8 m%, cetane index increment was 7.3 units, diesel yield of the reference catalyst was 98.3 m%, and the cetane index increment was 7.2 units; under the pressure of 6.0 MPa, the diesel product yield of the hydro-upgrading catalyst was 99.1 m%, cetane index increment was 6.1 units, diesel yield of the reference catalyst was 98.7m%, and the cetane index increment was 5.3 units. In addition, preparation repeatability, activity stability, and regeneration performance tests of the hydro-upgrading catalyst were carried out. |
