The studies on adsorption states of dibenzothiophene over CoMo/gamma-Al_2O_3catalyst

摘要

Due to more and more strict environmental regulations,the deep hydrodesulfurization(HDS) of diesel oil to produce "cleaner" fuel becomes a major challenge for scientists.Dibenzothiphenes (DBTs,such as dibenzothiophene(DBT),4-methyldibenzothiophene(4-MDBT),4,6-dimethyl-dibenzothiophene (4,6-DMDBT) are found the refractory compounds to HDS,so the studies of HDS mechanism of DBTs attributes more attention than ever (1approx5).
