Methods for using pyrolysis oil as a feedstock for making naphthenic process and lube oils

A method for producing a naphthenic process or lube oil, the method comprising the steps of:

• blending residual bottoms from a naphthenic crude atmospheric distillation unit with a pyrolysis oil that has been pretreated to reduce the amount(s) of one or more of minerals, metals, halides, alkenes or olefins in the pretreated pyrolysis oil, in a feedstock blending and storage unit to produce a blended feedstock;
• vacuum distilling the blended feedstock to provide one or more blended vacuum gas oils in one or more viscosity ranges;
• and
• hydrotreating the one or more blended vacuum gas oils in the presence of hydrogen and a non-noble metal catalyst to provide the naphthenic process or lube oil.

A method for producing a naphthenic process or lube oil, the method comprising the steps of:

• blending naphthenic crude with pyrolysis oil in a feedstock blending and storage unit to provide a blended feedstock;
• atmospheric distilling the blended feedstock to provide one or more blended atmospheric gas oils in one or more viscosity ranges and residual bottoms;
• vacuum distilling the residual bottoms to provide one or more blended vacuum gas oils in one or more viscosity ranges;
• and
• hydrotreating, in combination or separately, the one or more blended atmospheric gas oils and the one or more blended vacuum gas oils to provide the naphthenic process or lube oil.

A method for producing a process or lube oil meeting naphthenic specifications, the method comprising the steps of:

• pretreating a rubber pyrolysis oil by hydroprocessing in the presence of hydrogen and a non-noble metal catalyst to provide a pretreated pyrolysis oil having reduced amount(s) of one or more minerals, metals, halides, alkenes or olefins;
• vacuum distilling or otherwise fractionating the pretreated pyrolysis oil to provide treated oil(s) having one or more viscosity ranges;
• and
• hydrotreating the treated oil(s) in the presence of hydrogen and a non-noble metal catalyst to provide process or lube oils, using hydroprocessing and hydrotreating conditions to provide process or lube oils meeting naphthenic specifications.
