Abstract

Katalizatorlar tarkibining katalitik xarakteristikalarga ta’sirini aniqlash uchun 290⁰C haroratda, 0.5 MPa bosim, 1000 soat^-1 hajm tezligida va H₂/CO=2 nisbatda sinovlar o‘tkazildi.Katalizatorni ushlab turuvchi modda sifatida Navbahor O‘zbekiston Respublikasi bentonitidan olingan yuqori kremniyli seolit ishlatildi [1] Reaktordan chiqayotgan gaz, azotdan tashqari, katta miqdordagi komponentlar: reaksiyaga kirishmagan uglerod va vodorod monooksidi, alkanlar va C₁-C₄ olefinlarga ega. Sintezning chiqish moddalari va gazsimon mahsulotlar tahlili personal kompyuterga biriktirilgan “Kristallyuks-4000M” asbobida gaz-adsorbsion xromatografiya usulida o‘tkazildi. Detektor-katarometr. Bunda ikkita xromatografik ustun ishlatildi. CO va H₂ ni ajratish uchun CaA (3m x 3 mm) molekulyar elaklar bilan to‘ldirilgan ustun qo‘llanildi. Harorat rejimi: izotermik, 80⁰S. Gaz-tashuvchi-geliy, 20 ml/min. СO₂ va С₁-С₄ ni ajratish uchun HayeSep (3 m x 3 mm) bilan to‘ldirilgan ustun qo‘llanilgan. Harorat rejimi: dasturlangan, 80-200⁰S, 8⁰C/min. Gaz-tashuvchi-geliy, 20 ml/min. Tipik xromatografiya (1-rasm) da keltirilgan [2].
