Title:
A METHOD FOR RECOMBINING CATALYTIC HYDROCARBONS
Document Type and Number:
WIPO Patent Application WO/2005/003261
Kind Code:
A1
Abstract:
The present invention discloses a method for recombining catalytic hydrocarbons, which is fed onto the main catalytic fractional column for fractionating to get gasoline, diesel and a medium fraction. The medium fraction or the mixture of medium fraction and gasoline fraction is divided into aromatics and nonaromatics after the processing of aromatics extraction. Then the aromtics is fractionated to get high octane value gasoline, which is blended with the former gasoline fraction to increase its octane value, on the other hand, the nonaromatics is fractionated to get diesel, which is blended with the former diesel fraction to increase its cetane value and yielding. Compared with the prior art, the method with less investment and lower production cost is not limited by raw material and also can increase the final production items.
