Abstract

This paper studies the effect of methanol on catalytic conversion for Yemeni gasoline distillate. In this investigation, a modified zeolite catalyst carried by aluminum-silicate is used for increasing of reaction area and decreasing of operation temperature. Operation conditions are and atmospheric pressure. In presence of methanol, it is noted that the conversion percentage increases up to higher level (from 47 % to 86 %). This positive effect leads to increase the yield of aromatic (from 22 % to 34 % wt.) and olefins (from 20 % to 40.1 % wt.). Beside that, it is found that the addition of methanol allows decreasing the temperature of process from to with the conservative of the same conversion point and required productions at catalytic conversion for individual gasoline.
