Title:
二酸化炭素の排出を低減させた流動接触分解法
Document Type and Number:
Japanese Patent JP5766434
Kind Code:
B2
Abstract:
This invention concerns a fluid catalytic cracking (FCC) process with reduced carbon monoxide emission which modifies the regeneration phase of the spent catalyst by using pure oxygen without the need for dilution when burning coke adhering to the catalyst. In addition, this invention improves the reconditioning stage of the catalyst, incorporating a reconditioner supplementary to a conventional reconditioner which employs nitrogen as a carrier gas in the reconditioning of the already regenerated catalyst.
