Different daily used products depend on catalytic processes: fuel, energy, plastics, cosmetics, pharmaceuticals products, etc. Considering the wide spread application of catalytic processes, and knowing that transport and environment are priority for some researches; this paper is focus on production of fuel (especially gasoline), that needs two important catalytic processes unit: Fluid catalytic cracking and catalytic reforming. Studies and development of design and modeling of fluid catalytic cracking and catalytic reforming were reviewed in this paper. At last, some paths were lighted in aim to pursue a design and modeling study further. Keywords: Catalytic process, Fluid catalytic cracking (FCC), Catalytic reforming (CR), design, modeling, Gasoline. INTRODUCTION It has been many centuries since the catalyst technology was used in wide sectors. Firstly used in 1875 in production of sulfuric acid, catalyst usage have been developed in several fields such in production of nitric acid (1903), ammonia synthesis (1908-1914), catalytic cracking process (1935-1940) that change the energy evolution, catalytic hydrocarbon process (reforming in 1950) and hydrotreating (1960)(Guwahati, 2014). With the propriety of not altered reversible of equilibrium of reactions, and to accelerate both forward and reverse reactions, the presence of catalyst can result in different product distribution. That is why we have operation such as decomposition some molecules and reforming of others. Gas and oil is one of the sector need the most such properties held by catalyst. In fact, in refining and petrochemical industries, presence of catalyst is a very important in reforming process for producing high octane gasoline, aromatic feedstock and hydrogen in petroleum (Hu, Su and Chu, 2002). And the process of catalytic cracking is used to convert higher- molecular-weight hydrocarbons to lighter. As ensure by Sadeghbeigi (2012), amongst conversion processes cracking is the key unit used in modern refinery. The
