摘要: This study focuses on the modification of ZSM-5 in order to enhance catalytic cracking refinery naphtha produce light olefins. was metal modified using different loadings (0.5–5 wt%) Fe and Cr via impregnation method. The samples are compared effect loading physicochemical properties performance is investigated. had an both catalysts as well activity selectivity. Metal caused a decrease specific surface area which decreased further with increased loading. greater total acidity particular strong acid sites when Cr. optimum established promoted selectivity olefins, propylene. also dominant P/E ratio remarkable five achieved enhanced stability catalyst. found be good promoter for BTX products two-fold increase observed Fe-modified catalysts.
