Abstract: The components of coke, which were deposited on the MgO modified H-Mordenite zeolite, were studied by the 13C CP/MAS NMR spectral editing method in the present paper.The result shows that the major coke components were alkyl carbon and aromatic carbon,and the amount of deposited coke was dramatically reduced by the modified H-Mordenite zeolite.
