The process of conversion of light alkanes into aromatic hydrocarbons on zeolite catalysts, modified with Zn, La, Fe and Zr was investigated in this work. The catalysts were tested in the conversion process of propane-butane and propane-propylene mixtures at atmospheric pressure, variation of temperature and space velocity (SV). It is observed that the maximum amount of aromatic hydrocarbons (34.6%) are formed in the conversion of propane-butane mixture over Zn-La-Fe-ZSMAl 2 O 3 catalyst at 550 o C, selectivity to aromatic hydrocarbons is 39,2%.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
