Title:
生成物分布を改善するための触媒変成処理
Document Type and Number:
Japanese Patent JP2013537926
Kind Code:
A
Abstract:
The present invention relates to a catalytic conversion process for improving the product distribution, characterized in that a feedstock oil of good quality is contacted with a hot regenerated catalyst having a lower activity in a reactor to carry out a cracking reaction, the reaction product is separated from the spent catalyst to be regenerated, then the reaction product is fed into a separation system, and the spent catalyst to be regenerated is stripped, regenerated and recycled in the process. The isobutene content in the liquefied petroleum gas (LPG) produced by the process is increased by a factor of more than 30%, and the olefin content in the gasoline composition may be increased to more than 30 wt. %. The product distribution is optimized, and the yields of dry gas and coke are decreased, so as to sufficiently utilize the petroleum resources.
