Abstract
The effects of reactions, different paraffins as reactants, and different zeolites as catalysts on the cracking-desulfurization of thiophene contained paraffins were studied. Low temperature, low space, velocity, and high catalyst/oil ratio were found to favor the cracking-desulfurization reaction. The activities of different zeolites for the cracking-desulfurization reaction were attenuated in the following order: HY, Hβ, and HZSM-5. The cracking of thiophene was closely related to the paraffin used and to its cracking ability. The reaction conditions, which favored the hydrogen transfer reaction, also promoted the cracking-desulfurization of thiophene.
