Optimization Test of Catalyst in Pre-refining Process of Molecular Sieve Dewaxing Unit

The catalyst used in hydrogenation refining process in the production of aviation kerosene of the grade of imported product displacement is selected by comparison evaluation of four kinds of hydrogenation refining catalyst produced at home and abroad. The optimal technical parameters are studied and the regeneration properties are evaluated. The results of the test show that the catalyst selected has good stability, good anti-carbon deposit capability and good regeneration properties. It is suitable for use in different kinds of raw material aviation kerosene.
