Abstract:

The modification of Ni and Co is carried out for the catalyst carriers prepared with type A, B, C and D molecular sieves and various kinds of catalysts are used to do the hydrocracking reaction experiment of PRO resid. The analysis shows that the total conversion rate of condensed aromatics and selection of monocyclic ring compound are related with the pore diameter of catalyst, the metal content has also the effect on them, while the relationship of the selectivity of dicyclic compound and these factors is not obvious.
