Abstract

The research included preparing the used catalyst (zeolite) for reforming of naphtha. The process was carried out by adding certain proportions of  naphtha and  the catalyst  to the autoclave reactor with a capacity of (300 cm³) under initial conditions (150, 200, 250, 300 ̊C, catalyst ratio was 0.5% and  reaction time was one hour). Naphtha samples were measured firstly by (1HNMR and FTIR), it was found that the best temperature for reforming  for naphtha was (300°C) .The optimal conditions for this process were adjusted by increasing the catalyst ratio and reaction time, and it was found that the best conditions are ( The catalyst ratio is 2.5% and the reaction time is 3 hours. The used catalyst showed the ability to cyclisation of paraffins and dehydrogenation of paraffins and naphthenes, which led to an increase the ratio of aromatic compounds from (7.09%) to (29.13%) . In addition to the previous measurements, the gas chromatography of one of the naphtha samples was measured and was identical to those measurements.
