Abstract

Abstract A method for the two-step catalytic hydrogenation treatment of a heavy hydrocarbon oil which comprises first contacting the heavy hydrocarbon oil with a first solid catalyst comprising a metal component having catalytic activity for hydrogenation supported on a zeolite having catalytic activity for cracking a hydrocarbon, said zeolite having a (i) pore size distribution curve with two peaks, one peak in the range of 5 to 50 nm pore diameter and the other peak in the range of 50 to 1000 nm pore diameter and (ii) the volume of the pores having a diameter of 100 nm or larger is at least 0.05 ml/g; and then contacting the heavy hydrocarbon oil which had been contacted with said first catalyst, with a second catalyst, said second catalyst having hydrogenation activity and which is different from said first catalyst.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 142 words
A method for the two-step catalytic hydrogenation treatment of a heavy hydrocarbon oil which comprises first contacting the heavy hydrocarbon oil with a first solid catalyst comprising a metal component having catalytic activity for hydrogenation supported on a zeolite having cataytic activity for cracking a hydrocarbon, said zeolite having a (i) pore size distribution curve with two peaks, one peak in the range of 5 to 50 nm port diameter and the other peak in the range of 50 to 1000 nm pore diameter and (ii) the volume of the pores having a diameter of 100 nm or larger is at least 0.05 ml/g; whereby a hydrocracked product is formed; and then contacting said hydrocracked product with second catalyst, said second catalyst being a catalyst having hydrogenation activity and which is different from said first catalyst, whereby a hydrogenated product is formed.
Claim 2
Independent Claim 142 words
A method for the two-step catalytic hydrogenation treatment of a heavy hydrocarbon oil which comprises first contacting the heavy hydrocarbon oil with a first solid catalyst comprising a metal component having catalytic activity for hydrogenation supported on a zeolite having cataytic activity for cracking a hydrocarbon, said zeolite having a (i) pore size distribution curve with two peaks, one peak in the range of 5 to 50 nm port diameter and the other peak in the range of 50 to 1000 nm pore diameter and (ii) the volume of the pores having a diameter of 100 nm or larger is at least 0.05 ml/g; whereby a hydrocracked product is formed; and then contacting said hydrocracked product with second catalyst, said second catalyst being a catalyst having hydrogenation activity and which is different from said first catalyst, whereby a hydrogenated product is formed.
Claim 3
Dependent Claim 27 words
The method of claim 1 wherein the volume of the pores of said zeolite having a diameter of 100 nm or larger is at least 0.08 ml/g.
Claim 4
Dependent Claim 44 words
The method of claim 2 wherein in said first solid catalyst, said metal component having catalytic activity for hydrogenation belongs to the VIB Group of the Periodic Table and is in an amount from 8 to 20% by weight of said first solid catalyst.
Claim 5
Dependent Claim 44 words
The method of claim 2 wherein in said first solid catalyst, said metal component having catalytic activity for hydrogenation belongs to the VIII Group of the Periodic Table and is in an amount from 1.5 to 8% by weight of said first solid catalyst.
