Definitions
- the present invention relates to a method for producing a catalyst used for hydrorefining of hydrocarbons such as petroleum fractions. Hydrodemetallization of heavy oils, that is, various heavy fractions obtained by normal or reduced pressure distillation of crude oil, evening sand, shale oil, or coal liquefied oil, etc., and residual oil
- the present invention relates to a catalyst used for: Background art
- Heavy oil such as residual oil from atmospheric distillation or vacuum distillation contains a large amount of metals such as nickel and vanadium. This metal component poisons the hydrorefining catalyst for desulfurization, denitrification, decomposition, etc., and lowers the catalytic activity.
