The alkylation of thiophenic compounds with olefins in real fluid catalytic cracking (FCC) gasoline was carried out over three kinds of acidic catalysts: HY zeolite, phosphoric acid supported on both kieselguhr and purely siliceous MCM-41 zeolite. The results showed that the MCM-41 supported phosphoric acid catalyst was the most promising to be utilized in the reaction in terms of its activity and stability. Based on its excellent catalytic performance, apparent kinetic models for alkylation of the major thiophenic sulfides were proposed, thus allowing use of the simulation in reaction distillation (RD) technology. Furthermore, numerical regression led to kinetic parameters with narrow spans, suggesting that the proposed models satisfactorily simulate the sulfides removal under the suggested reaction conditions.

“…It can be handled under relatively mild conditions, with a minimal loss of octane number and without any hydrogen consumption. The desulfurization efficiency can be enhanced by increasing the alkylating agent/sulfur ratio [8][9][10]. The performance of this process is influenced by side reactions such as olefin polymerization and Saudi Aramco: Company General Use 5 alkylation of aromatic hydrocarbons.…”

“…various zeolites (HY, USY, MCM-22 etc.) [4][5][6] and supported heterogeneous acid [7,8]. In the initial phase of the process, some of these solid catalysts have high catalytic activity and selectivity, but later the formation of carbon deposition will cause rapidly decaying reactivity, especially at high temperature [9].…”
