Abstract:
A hydroprocessing process comprising:a) reacting a hydrocarbonaceous feed with hydrogen in a first hydroprocessing reaction stage in the presence of a first catalytically effective amount of a hydroprocessing catalyst, under first catalytic conversion conditions, to form a first stage effluent comprising a hydroprocessed hydrocarbonaceous liquid and a vapor; b) passing said first stage effluent to a stripping stage wherein it is contacted with a stripping gas to form a stripped first stage liquid effluent and a vapor effluent comprised of the first reaction stage vapor and said stripping gas; c) removing said vapor effluent; d) passing said stripped liquid and hydrogen into a second reaction stage in which they react in the presence of a second catalytically effective amount of a second hydroprocessing catalyst under second catalytic conversion conditions, to produce a second stage effluent comprising a hydroprocessed liquid product and a vapor which contains unreacted hydrogen, the first hydroprocessing stage, second hydroprocessing stage, and stripping stage being in a common vessel; e) passing said second stage vapor effluent into said first stage; and f) removing said hydroprocessed liquid product from said vessel.
