Abstract
A process is provided for converting a heavy hydrocarbon oil into light hydrocarbon fuels by thermal cracking or hydrocracking, which comprises adding to about 100 parts by weight of the heavy hydrocarbon oil feedstock (A) about 0.1 to 50 parts by weight of a substance (B) which is a hydrogenated oil obtained by aromatic ring hydrogenation of about 430.degree.-600.degree. C. thermal-treated or cracked petroleum feedstock product oil boiling higher than about 200.degree. C. to hydrogenate abot 20 to 90% of the aromatic rings present.
Claims18
A thermal cracking process for converting a heavy hydrocarbon oil into light hydrocarbon fuels, which comprises:
- to about 100 parts by weight of the heavy hydrocarbon oil feedstock (A) being added about 0.1 to 50 parts by weight of a substance (B) selected from hydrogen-donor substances each of which comprises a hydrogenated oil having a boiling point of about 330.degree.-600.degree. C. and obtained by aromatic ring hydrogenation of a thermal-treated product oil boiling higher than about 200.degree. C., said aromatic ring hydrogenation being conducted so as to hydrogenate about 20 to 90% by weight of the aromatic rings present in the product oil, said thermal treating being conducted at about 430.degree. to 600.degree. C. by using a catalytic-cracked or catalytic-reformed product boiling higher than about 200.degree. C., said catalytic cracking or catalytic reforming being conducted by using a petroleum feedstock and thereafter thermal cracking the composition containing A and B.
A hydrocracking process for converting a heavy hydrocarbon oil into light hydrocarbon fuels, which comprises:
- to about 100 parts by weight of the heavy hydrocarbon oil feedstock (A) being added about 0.1 to 50 parts by weight of a substance (B) selected from hydrogen-donor substances each of which comprises a hydrogenated oil having a boiling point of about 330.degree.-600.degree. C. and obtained by aromatic ring hydrogenation of a thermal-treated product oil boiling higher than about 200.degree. C., said aromatic ring hydrogenation being conducted so as to hydrogenate about 20 to 90% by weight of the aromatic rings present in the product oil, said thermal treating being conducted at about 430.degree. to 600.degree. C. by using a catalytic-cracked or catalytic-reformed product boiling higher than about 200.degree. C., said catalytic cracking or catalytic reforming being conducted by using a petroleum feedstock and thereafter hydrocracking the composition containing A and B.
