Irregularly shaped non-spherical supported catalyst, and a process for hydroconversion heavy oil fractions
摘要:
A catalyst for hydrotreating and/or hydroconverting heavy metal-containing hydrocarbon feeds, comprises a support in the form of mainly irregular and non-spherical alumina-based agglomerates the specific shape. The catalyst is prepared by a specific order of steps: crushing, calcining, acidic autoclaving, drying, further calcining and impregnation with catalytic metals.
