Title:
FCC法における金属不動態化のためのLa/Nd-スピネル組成物
Document Type and Number:
Japanese Patent JP3734274
Kind Code:
B2
Abstract:
Catalytic cracking catalysts and additives which comprise a metals passivation component containing: 15-60 parts by weight MgO, 30-60 parts by weight Al2O3, and 10-30 parts by weight rare earth compound selected from the group consisting of La oxide, Nd oxide, and mixtures thereof, wherein at least a portion of the MgO and Al2O3 are in the form of an Mg-Al oxide spinel, are especially useful for catalytic cracking processes involving hydrocarbon feedstocks containing high metals (e.g. vanadium) content. The La/Nd compound may be one which forms La and/or Nd oxide during the FCC process cracking or regeneration step.
