Method of upgrading oils containing hydroxyaromatic hydrocarbon compounds to highly aromatic gasoline

A multi-stepped method for producing highly aromatic gasoline, comprising the steps of:

• deoxygenating unsaturated multiple ring hydroxyaromatic hydrocarbon compounds in a raw oil material at a temperature of 300.degree. C.-450.degree. C. to produce a deoxygenated oil material containing multiple ring aromatic compounds;
• removing water from the deoxygenated oil material;
• cracking the multiple ring aromatic compounds in the presence of hydrogen and a dual function cracking catalyst having a strongly acidic support to produce a cracked oil material containing single ring aromatic compounds;
• and
• distilling the cracked oil material to remove the single ring aromatic compounds as gasoline.

A multi-stepped method for producing single ring aromatic compounds, comprising the steps of:

• deoxygenating a raw material containing unsaturated multiple ring hydroxyaromatic hydrocarbon compounds at a temperature of 350.degree. C.-450.degree. C. to produce a deoxygenated material containing multiple ring aromatic compounds;
• removing water from the deoxygenated material;
• and
• cracking the multiple ring aromatic compounds in the deoxygenated material in the presence of hydrogen and a dual function cracking catalyst on a strongly acidic support to produce a material containing single ring aromatic compounds.

A multi-stepped method of producing highly aromatic gasoline, comprising the steps of:

• deoxygenating unsaturated single and multiple ring hydroxyaromatic hydrocarbon compounds in a raw oil material, by contacting the material with a sulfided cobalt-molybdenum catalyst on an alumina support at a pressure of 1500 to 3000 psig and a temperature of 300.degree. C. to 450.degree. C., to produce a deoxygenated oil material containing single and multiple ring aromatic compounds;
• removing water from the deoxygenated oil material;
• distilling the resulting deoxygenated oil material to remove the single ring aromatic compounds as gasoline and leave a tenate;
• after the distilling, cracking the multiple aromatic compounds remaining in the tenate, by contacting the tenate with a sulfided nickel and molybdenum catalyst on a silica alumina support in presence of hydrogen at a pressure of 1500 to 3000 psig and a temperature of 300.degree. C. to 450.degree. C., to produce a cracked oil material containing single ring aromatic compounds;
• and
• distilling the cracked oil material to remove the single ring aromatic compounds as gasoline.
