考察了不同的沸石催化剂、不同反应条件和不同的共反应烃类化合物对含噻吩烃类裂化脱硫的影响。结果表明 ,有利于氢转移反应的条件亦可促进含噻吩烃类的裂化脱硫。烃类化合物与噻吩间的双分子氢转移反应看来是裂化脱硫的可信的反应途径。四氢噻吩的形成与分解是该反应的关键步骤
The effects of different zeolite catalysts, different reaction conditions and different co-reacted hydrocarbons on the cracking and desulfurization of thiophene-containing hydrocarbons were investigated. The results show that the conditions favoring the hydrogen transfer reaction also promote the cracking desulfurization of thiophene-containing hydrocarbons. The bimolecular hydrogen transfer reaction between hydrocarbon compounds and thiophene appears to be a credible reaction pathway for cracking desulfurization. The formation and decomposition of tetrahydrothiophene is a key step in this reaction
