Title:
触媒を用いた転換によるイソブタンおよびイソパラフィンの含有率が高いガソリンの製造方法
Document Type and Number:
Japanese Patent JP3996320
Kind Code:
B2
Abstract:
A catalytic transform process for reducing the content of olefin in liquefied gas and gasoline features that in the complex reactor composed of lifting tube or lifting tube and fluidized bed, preheated raw oil comes into lifting tube from its lower end and is contacted with catalyst, the oily gas generated after reaction is lifted up to middle or top of lifting tube, where it is in contact with cooled catalyst for continuous reaction, the resultant flowing out after reaction comes into settler, the reaction resultant is separated. The catalyst is divided into two portions after stripped and regenerated, one coming into lower end of lifting tube and another into middle or top of lifting tube. With said process, the butylene in liquefied gas is decreased to 17.5 wt.% and the isobutane in it is increased to 37.04 wt.%, and the olefin in gasoline is decreased to 12.32 wt.% and the isoparaffin in it is increased to 41.83 wt.%.
