Abstract
The effect of different zeolites as catalysts, reaction conditions, and the type of hydrocarbons as co-reactants on the cracking-desulfurization of thiophene contained in hydrocarbons were investigated. Experimental results showed that the reaction conditions favoring the hydrogen transfer reaction also promoted the cracking desulfurization of thiophene. Hydrogen transfer through a bimolecular reaction between hydrocarbons and thiophene species seems to be the convincible reaction pathway for achieving desulfurization. The formation and decomposition of tetrahydrothiophene are the key steps in the reactions.
