Process for the catalytic conversion of hydrocarbon oils.

摘要

Hydrocarbon oils of which more than 70% by volume boils above 360 DEG C and which have a C5-asphaltenes content of more than 2.5% by weight are contacted at elevated temperature and pressure in the presence of hydrogen with a supported molybdenum containing catalyst, in which process hydrocarbon oils containing substantial amounts of nickel are converted at a pressure of at least 80 bar, using a supported molybdenum containing catalyst having an average pore diameter in the range 30-80 nm.
