EFFECT OF PROMOTER METALS ON CATALYST ACTIVITY IN PROPANE-BUTANE FRANCOATION
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. Тадқиқотлар оқимли дифференциал каталитик қурилмада катализаторнинг ҳаракатсиз фазасида (катализаторнинг ҳажми 6 см3), 450-6500C да, одатдаги атмосфера босими (P = 0,1 МПа) да, дастлабки газлар аралашмасининг ҳажмий тезлиги 600-1000 соат-1 бўлган шароитда ўтказилди. Молибден асосида тайёрланган цирконий турли миқдори бўйича тажрибалар олиб борилди. Бундан ташқари Zr-Mo асосидаги таркибли катализаторга рух ва галлий оксидларини киритиш орқали пропан-бутан фракциясини каталитик ароматлаб ароматик углеводородлар олиш жараёни таҳлил қилинди. Катализаторларни тайёрлашда фойдаланилган металл окидларнинг ароматлаш жараёнига ва коксланишга таъсири ўрганилди.
