ВЛИЯНИЕ МЕТАЛЛОВ-ПРОМОТОРОВ НА АКТИВНОСТЬ КАТАЛИЗАТОРА ПРИ АРОМАТИЗАЦИИ ПРОПАН-БУТАНОВОЙ ФРАКЦИИ
Abstract
Ишда пропан-бутан фракциясидан ароматик углеводородлар олиш реакциясининг тезлигига фаол компонентлар таркибининг таъсири ўрганилган. Ароматик углеводородлар олиш реакциясида танланган катализаторларнинг каталитик фаоллигига турли омилларнинг таъсири баҳоланган. Катализаторларни тайёрлашда металлар юттириш усули билан амалга оширилди. Таркибида молибден сақлаган мезоғовакли, юқори кремнийли алюмосиликатли пропан-бутан фракциясини оксидловчилар иштирокисиз катализатор иштирокида ароматлаб ароматик углеводородлар олиш учун танланган катализаторида цирконийнинг миқдори 2,0% га ошса, кислоталик марказлар концентрациялари 120 мкмоль/г га камайиши кузатилди. Натижада кислоталик марказларининг нисбатлари ўзгаради, бу эса мезоғовакли, юқори кремнийли алюмосиликатнинг кислоталик хоссаларининг ўзгаришига сабаб бўлади.
