Abstract
Light aromatic compounds such as benzene, toluene, xylenes are valuable products which can be produced from upcycling processes of plastic waste. Light olefins, especially ethylene, tends to be the side product from these upcycling processes. Ethylene, which can also be derived from other non-conventional resources like biomass, natural gas etc., can be subjected to aromatization using zeolite catalyst (ZSM5) in order to increase the overall yield of aromatics from these upcycling processes. Moreover, using a suitable promoter along with HZSM-5 catalyst,higher selectivity of para-xylene can be obtained which in turn would prove to be beneficial in terms of the economics of the process since para-xylene is one of the most sought-after aromatic compounds. In this study, phosphorus is studied as the promoteron HZSM-5 as it has the potential to be an effective catalyst considering its behaviour in aromatization of methanol, which has a similar reaction mechanism as that for ethylene. The result from this work showed that the use of small amounts of phosphorus in the catalyst does improve the selectivity and overall yield of para-xylene as compared to unmodified ZSM-5. Different amounts of phosphorus catalyst were tested to find the most optimum ratio to obtain better selectivity of p-xylene. These catalysts were characterized using NH3-Temperature programmed desorption, X-ray diffraction, and N2-physisoprtion techniques.
