Oligomerization of C4 Fraction from FCCU on ZSM-5

In order to make more liquid products like gasoline, the oligomerition of a C4 feedstock taking place on catalyst containing ZSM-5 was studied in a pressurized reactor. The products were C5- gas, liquid hydrocarbons and coke. During the reaction on the catalyst BO-l, when the WHSV was 0.71h-1 and to...

description	In order to make more liquid products like gasoline, the oligomerition of a C4 feedstock taking place on catalyst containing ZSM-5 was studied in a pressurized reactor. The products were C5- gas, liquid hydrocarbons and coke. During the reaction on the catalyst BO-l, when the WHSV was 0.71h-1 and total pressure was 4.0MPa, the C5+ product yield reached a maximum at a temperature around 320℃. As oligomerization reaction was the dominating one, there were minor C9 hydrocarbons in liquid products and the main products were C7 and C8 olefins and n- C10 paraffins. When the temperature was higher than 286C, a small amount of C9hydrocarbons was formed and more normal and isomeric paraffins other than olefins were formed in products.Gasoline yield increased linearly with a rising total pressure under the same operating conditions.
