Abstract: Paraffin�s and olefins in the cracked naphtha can be transformed into aromatics and iso-paraffins to reduce the olefins content as well to improve the octane number of the gasoline commercial fraction. In this work Ni-HZSM-5 bifunctional catalyst was prepared by ion exchange with Ni(NO3)2 aqueous solution. The activity of Ni-HZSM-5 (wt.% 1.34% Ni) catalyst prepared by ion exchange method was investigated in the conversion of light hydrocarbons resulted as by-products of petroleum refining process (mixtures o… Show more

“…From the diffractogram [33][34][35][36][37][38][39], the interplanar distances dhkl and the corresponding relative intensities (I/I0) were calculated. The calculated dhkl values agree very well with that reported for ZSM-5 (MFI) zeolite [89].…”

“…Many studies have focused on the ability of the monofunctional acid catalyst HZSM-5 to convert light hydrocarbons to BTX [18,19,21,23,25,33,39,51,73]. HZSM-5 transforms light alkanes and alkenes to products of very similar composition consisting mainly of C6 -C10 aromatics (with low selectivity, about 12%) and C1 -C4 aliphatics (especially methane and ethane).…”

“…Zn 2+ and Ni 2+ cations increase the reversibility of hydrogen adsorption-desorption steps. As in the case of gallium exchanged HZSM-5 zeolites these reactions appear to proceed via bifunctional pathways involving acid -OH groups and exchanged metal cations [25,26,43,53,54,60,82].…”
