Title:
FLUID CATALYTIC CRACKING CATALYST, FLUID CATALYTIC CRACKING METHOD, FLUID CATALYTIC CRACKING APPARATUS, AND METHOD FOR EVALUATING STRIPPING PERFORMANCE OF FLUID CATALYTIC CRACKING CATALYST
Document Type and Number:
Japanese Patent JP2021037444
Kind Code:
A
Abstract:
To provide a fluid catalytic cracking catalyst excellent in stripping performance capable of reducing stripping coke, a fluid catalytic cracking method using the fluid catalytic cracking catalyst, a catalytic cracking apparatus equipped with the fluid catalytic cracking catalyst, and a method for evaluating a stripping performance of a fluid catalytic cracking catalyst.SOLUTION: There is provided a fluid catalytic cracking catalyst used in a fluid catalytic cracking method, in which a cracking reaction of raw material oil, a stripping treatment, and a regeneration treatment by heating are repeated in this order. In a gas chromatography and a mass spectrometry analysis, a difference between in the case where the fluid catalytic cracking catalyst after the cracking reaction and before the stripping treatment is pretreated under a specific pretreatment condition 1 and in the case where the fluid catalytic cracking catalyst after the cracking reaction and before the stripping treatment is pretreated under a specific pretreatment condition 2 in a ratio (A/T) of a total peak (A) area derived from an aromatic hydrocarbon having 12 or more carbon atoms to a total peak area (T) derived from an aromatic hydrocarbon remaining in the fluid catalytic cracking catalyst is a constant value or less.SELECTED DRAWING: Figure 1
