Catalytic reaction of ethanol into light olefins over 2wt%CuO-HZSM-5

There was increasing in the international needing for fossil fuel, which is formed from nonrenewable materials such as crude oil. Bio-ethanol considered one of the materials that can be produced from renewable sources like the fermentation of sugar cane. 2wt% CuO doped HZSM-5 has been modified by the impregnation method. All experimental runs have conducted at 500 °C, 1 atmosphere pressure and WHSV 3.5 h-1 in a fixed bed reactor. Catalyst, which modified in this work, was analyzed by SEM and XRD as well as TGA experiment. The analysis hydrocarbons products have done by gas chromatographs provided with flame ionization detector (FID) and thermal conductivity detector (TCD). It has been studied CuO doped HZSM-5 catalyst gives higher ethanol conversion and yield especially light olefins as compared to HZSM-5 parent catalyst. In addition, reduces the coke formation over HZSM-5, therefore, enhanced the life of HZSM-5 catalyst.
