As China's well-off will be fully completed in 2020, which will promote the improvement of people's living standards, environmental awareness and the attendant national automotive holdings will be increasing. Cars will be more demand for oil, but oil sulfur oxide sintered generated is a major pollutant, SO2 is the cause of which generate acid rain, much concerned with vehicle exhaust haze also related to serious harm ecological environment and human health. So people want to have environmentally friendly and convenient travel and urgent need, the state and the people of the sulfur content of fuel put forward higher requirements.

This study investigate the pore structure of adsorbent (CeX, CeL, CeMordenite, CeZSM-5, CeA) how to influence the thiophene adsorption for model gasoline. High adsorption rate depend on pore size, when pore size of adsorbent come close to or greater than the diameter of thiophene easy to get high sulfur uptake.
