MOF-177£¬MOF-5£¬HKUST-1£¬ MOF-505£¬ and UMCM-150 were synthesized and activated according topublished procedures. Surface areas and pore volumes of the studied MCPs have been previously tabulated. Na(Y) zeolite (powder) wasobtained from Strem Chemicals and activated carbon (50-200mesh) was obtained from Fisher. Both were used as received.Dibenzothiophene (99%, Acros), 4,6-dimethyldibenzothiophene(97%, Aldrich), isooctane (HPLC grade, Fisher), and toluene (ACSreagent grade, Fisher) were used as received. Ultralow sulfur dieselwas obtained from Citgo in Ann Arbor£¬MI and was found tocontain 32 wt % aromatic compounds using H NMR methods and 21.5 ppmw S (13.2 ppmw S dibenzothiophene and 8.3 ppmwS 4,6-dimethyldibenzothiophene) using GC-FPD. Ultralow sulfur diesel was spiked to 300 ppmw S with DBT and DMDBT to obtain the solutions used in the experiments. Microporous coordination polymers (MCPs) are demonstrated to be efficient adsorbents for the removal of the organosulfur compounds dibenzothiophene (DBT) and 4,6-dimethyldibenzothiophene (DMDBT) from model diesel fuel and diesel fuel.Õâ¾ä»°ÖеÄMCPsµÄÖÐÎÄÎïÖÊÃû×Ö |
