Catalysts for hydrodemetallization of hydrocarbons containing metallic compounds as impurities and process for hydro-treating such hydrocarbons using such catalysts |
摘要 |
A catalyst obtained by admixing red mud with alumina or/and an alumina-containing substance, optionally adjusting the water content of the admixture and/or adding an organic binder to the admixture, kneading and shaping the admixture into pellets having suitable size and shape, and calcining the pellets of 600 DEG C to 1,100 DEG C. The catalyst has a high compression strength and can, when used in the hydrodemetallization of hydrocarbons, achieve a high rate of demetallization and a low yield of low boiling fractions. The rate of demetallization is enhanced when the process is carried out using a hydrogen feed containing hydrogen sulfide.
