Sulfur removal of commerical transportation fuels over a nickel based adsorbent

摘要

Deep desulfurization has become an increasingly difficult problem as the average quality of crude oils become poorer,and sulfur restrictions become tighter.Hydrodesulfurization (HDS) is the traditional method of removing sulfur,but it needs to work at high temperature and pressure and consumes a large amount of hydrogen.This limits its use in on-site and on-board fuel cell systems.The conventional HDS process is also difficult to produce the ultra-clean fuels with sulfur level less than Ippmw.
