Naphtha catalytic upgrading for production of environmentally- friendly gasoline

Abstract

The recent economic climate, impact of government regulation, and new market trends have impacted the catalyst designers to improve the performance of catalyst. To achieve this goal, a series of experiments were conducted to focus on the influence of Ga and Re addition on the catalytic activity of Pt-Re/Al2O3 naphtha reforming catalysts. To supported γ-Al2O3 the Ga-Re-Pt prepare by using incipient wetness impregnation method. Many characterization tests are used such as scanning electron microscopy, temperature programmed desorption, X-ray diffraction and BET surface area. The liquid product yield tested by PONA method. In this study the benzene content is used as main performance criteria throughout many experiments performed at different liquid hourly space velocity, hydrogen/hydrocarbon ratios and different operating temperature. According to the catalyst characterization tests the co-impregnation method showed good result in term of performance and properties. The catalyst exhibited good liquid product distribution and significant minimization of benzene content.
