Carbon materials mainly capture sulfur dioxide (SO2) from gas through physical adsorption, therefore their SO2 capture performance will decrease with the increase in desulfurization temperature. In order to meet the stringent requirements of deep desulfurization, further improvements on carbon materials are necessary, …
The current industrial method for removal of sulfur from fuels is hydrodesulfurization (HDS), which is a high temperature, high pressure catalytic process. This makes HDS a very costly option for deep desulfurization. Moreover, HDS is not effective for removing heterocyclic sulfur compounds such as dibenzothiophene (DBT) and its derivatives, especially 4,6 …
X-ray diffraction (XRD) patterns of ZIF-8, CuO and CuO-ZIF-8-n were shown in Fig. 2 a. It can be seen from the Fig. 2 a, the pattern of the synthesized ZIF-8 well matches that of simulated ZIF-8, indicating its high crystallinity and identical ZIF-type crystal structure. In addition, sample CuO exhibits two characteristic peaks at around 35.6 and …
