INVESTIGATION OF SULFURIZATION OF WATER-SOLUBILITY DISPERSED NI CATALYST DURING HEAVY OIL HYDROCRACKING

摘要

So far,the development and application in slurry-bed hydroprocessing of residue is more attention-getting than before.In slurry-bed hydroprocessing ,the dispersed-phase exiguous catalyst or additions be added into the reactor together with sulfuric agent,raw oil and hydrogen.In most research man viewpoint ,the catalyst can promote cracking and restrain coking of the big molecule compound in the reaction,simultaneously,catalyst can become carrier of cokes and decrease the coking of reactor wall obviously.
