HOW DOES VGO HDS ACTIVITY DEPEND ON FEED BOILING POINT?

摘要

Over the past years legislators have forced the oil industry to produce cleaner and more environmentally friendly fuel oils and transportation fuels [1,2,3]. Moreover further emphasis has been placed on the catalytic upgrading of heavy petroleum fractions and residues such as oils in the vacuum gas oil (VGO) range [4]. It is difficult to hydrotreat oils in this range down to low sulfur levels, as oils of that type normally contain significant amounts of the sulfur compounds, which are the most difficult to desulfurize [5].
