| Abstract: | The industrial application of RVHT technology in a 1.30 Mt/a wax oil hydrogenation unit was introduced. The results showed that the presulfu- rization effect of the speciality catalyst was better, the sulfurization ratio reached 98.1%. The operation for RVHT technology was stable, and the products were superior in quality. When the average reaction temperature was 347.5 ℃, the hydrodesulphurization ratio of raw material could reach 85%. The hydrogenated wax oil, as the feedstock of catalytic cracking unit, could significantly reduce the sulfur content in each of its products, for example, the sulfur content in gasoline reduced from 480 ug/g to 66 ug/g. |
