| Abstract: | The effects of ITQ-21 and ITQ-24 as zeolite additives on the catalytic pyrolytic oil using HMOR were investigated. The research was started by studying the effect of HMOR and its amount represented by the catalyst-to-tire ratio, and then followed by the effects of addition of the two ITQ zeolites into HMOR. The results showed that, with increasing the catalyst-to-tire ratio, the gasoline and kerosene yield increased in accordance with the reduction of the heavier fractions, and the concentration of the saturated hydrocarbons in the pyrolytic oil was found to be higher. However, increasing the catalyst-to-tire ratio decreased the yield of liquid product. The two ITQ zeolite additives have strong effects on the pyrolytic oil. For example, as compared with the case of pure HMOR, adding ITQ-21 enhanced the production of kerosene whereas the introduction of ITQ-24 resulted in the higher concentration of aromatic compounds in the derived oil. In addition, the use of catalyst was found to enhance the selectivity of mono-aromatic in the light fraction, but adding ITQ zeolites caused a reduction in the selectivity of HMOR toward the production of mono-aromatics. The differences on the effects of the two ITQ zeolites were explained in relation with the catalyst characterization results. It was found that, the acid properties and topology played very important roles on the influences of these additives. |
