Abstract:
An integrated hydroconversion process comprising:a) combining a first refinery stream with a first hydrogen-rich gaseous stream to form a first feedstock;b) passing the first feedstock to a first reaction zone maintained at conditions sufficient to effect a boiling range conversion of the first refinery stream of at least about 25%, to form a first reaction zone effluent comprising normally liquid phase components and normally gaseous phase components;c) combining the entire first reaction zone effluent, to form a second feedstock;d) passing the second feedstock to a second reaction zone maintained at conditions sufficient for converting at least a portion of the aromatics present in the second refinery stream, to form a second reaction zone effluent;e) separating the second reaction zone effluent into at least one distillate fraction and a second hydrogen-rich gaseous stream; andf) recycling at least a portion of the second hydrogen-rich gaseous stream to the first reaction zone.
