Method for producing hydrotreated oil and method for producing catalytic cracked oil

Abstract

There is provided a method for producing hydrotreated oil comprising: a step of passing heavy hydrocarbon oil through a reactor filled with a hydrotreating catalyst to obtain hydrotreated oil, wherein the hydrotreating catalyst contains phosphorus, an iron group element, and a group 6 element; the ratio C 2 /C 1 of a content C 2 of the iron group element to a content C 1 of phosphorus in the hydrotreating catalyst is less than 0.60 in a molar ratio; and the average pore diameter of the hydrotreating catalyst is larger than 7.5 nm and smaller than 9.5 nm.

1 . A method for producing hydrotreated oil comprising:
 a step of passing heavy hydrocarbon oil through a reactor filled with a hydrotreating catalyst to obtain hydrotreated oil, wherein   the hydrotreating catalyst contains phosphorus, an iron group element, and a group 6 element;   a ratio C 2 /C 1  of a content C 2  of the iron group element to a content C 1  of phosphorus in the hydrotreating catalyst is less than 0.60 in a molar ratio; and   an average pore diameter of the hydrotreating catalyst is larger than 7.5 nm and smaller than 9.5 nm.   
     
     
         2 . The production method according to  claim 1 , wherein, in the hydrotreating catalyst,
 a ratio C 2 /C 3  of the content C 2  of the iron group element to a content C 3  of the group 6 element is less than 0.45 in a molar ratio, and   a ratio C 1 /C 3  of the content C 1  of phosphorus to the content C 3  of the group 6 element is larger than 0.23 in a molar ratio.   
     
     
         3 . A method for producing catalytic cracked oil comprising:
 a step of obtaining hydrotreated oil by the production method according to  claim 1 ; and   a step of obtaining catalytic cracked oil by fluid catalytic cracking of the hydrotreated oil.
