This patent describes an apparatus for producing distillates of lubes from paraffins, which comprise: (a) a dehydrogenation reactor including means for passing a paraffinic feedstock stream into a dehydrogenation zone at conditions of pressure and temperature selected to convert the paraffins to an olefin rich effluent stream comprising at least one of the group consisting of propylene and butylene; (b) a low pressure oligomerization catalytic reactor including means for contacting the olefin rich effluent stream in a low pressure oligomerization catalytic reactor zone with a crystalline zeolite oligomerization catalyst at conditions of pressure and temperature selected to convert olefins to a first reactor effluent stream rich in liquid olefinic gasoline range hydrocarbons; (c) a first means for separating the first reactor effluent stream to form a substantially liquid C/sub 5/+ rich stream and a C/sub 4/- rich stream; (d) means for passing the C/sub 5/+ rich stream to a high pressure oligomerization catalytic reactor zone; (e) a high pressure oligomerization catalytic reactor including means for contacting the substantially liquid C/sub 5/+ rich stream in the high pressure oligomerization catalytic reactor zone with a crystalline zeolite oligomerization catalyst at conditions of temperature and pressure selected to produce a second reactor effluent stream which is rich in distillate; (f) second means for separating the second reactor effluent stream to recover an olefinic gasoline stream and a distillate stream; and (g) a hydrotreating reactor including means for contacting the distillate stream with hydrogen in a hydrotreating unit to produce a hydrotreated distillate stream comprising lube range hydrocarbons.
