Abstract

The hydrogenation of 1,2,4-trimethylbenzene (1,2,4-TMB) was carried out over the zeolite catalysts of HZSM-5,HCOK-5, HBeta and HMCM-49 and bifunctional catalysts 2 %Ni/zeolite, which were prepared by incipient wetness impregnation. High catalytic performance was obtained on COK-5 zeolite under testing conditions. The conversion of 1,2,4-TMB rose from 59.4 % over HCOK-5 to 70.2 % over 2 %Ni/HCOK-5, so did the selectivity to BTX 37.6 % over HCOK-5 to 55.8 % over 2 %Ni/HCOK-5. In order to correlate their catalytic performances with their physicochemical properties, the catalysts were characterized by the joint use of various physicochemical characterization methods, such as XRD, TPD and TPR. The results showed that the excellent properties of both catalysts may be mainly assigned to the presence of a number of weakly acidic and intercrossing channels of 12MR + 10MR of HCOK-5. Improvement of the catalytic properties of 2 %Ni/HCOK-5 was related to the reduction of the nickel species bounded with the active zeolite Al-framework.
