ABSTRACT

Issledovaniya pokazali, chto sistemy na osnove oksida vanadiya na razlichnykh nositelyakh predstavlyayut bol'shoi interes dlya prigotovleniya katalizatorov v oblasti pererabotki prirodnogo gaza i organicheskogo sinteza. Vazhnym ehtapom v razvitii sernokislotnogo kataliza yavilos' sozdanie sul'fovanadievykh katalizatorov na diatomite. Katalizator prost v izgotovlenii, dostatochno prochen i imeet otnositel'no bol'shoi srok sluzhby. V vidu bol'shoi opasnosti otrabotannykh vanadievykh katalizatorov dlya cheloveka i okruzhayushchei sredy, a takzhe defitsitnosti i vysokoi tseny soedinenii vanadiya trebuetsya proizvodit' pererabotku dezaktivirovannykh vanadievykh kontaktnykh mass. V svyazi s ehtim voznikaet neobkhodimost' opredeleniya prichin dezaktivatsii sernokislotnykh vanadievykh katalizatorov marki SVD posle ikh ehkspluatatsii. Vse issledovannye obraztsy imeyut nizkuyu udel'nuyu poverkhnost' i poristost', chto ukazyvaet na razrushenie nositelya. Rentgenospektral'nyi analiz svidetel'stvuet o nizkom soderzhanii V2O5. Ehto svyazano s nalichiem primesei v diatomite. Oksidy alyuminiya i zheleza vzaimodeistvuyut s pirosul'fovanadatom kaliya, v rezul'tate ehtoi reaktsii obrazuyutsya alyumo- i zhelezokalievye kvastsy i, kak sledstvie, vydelyaetsya kristallicheskaya faza V2O5, chto privodit k rezkomu izmeneniyu sostava i svoistv aktivnogo komponenta i obuslovlivaet ponizhenie aktivnosti. Rezul'taty rentgenograficheskikh issledovanii pokazyvayut, chto vse issleduemye obraztsy soderzhat kristallicheskie formy diatomita preimushchestvenno v vide vysokotemperaturnoi modifikatsii – kristobalita. Znachitel'noe kolichestvo kristobalita privodit k narusheniyu mekhanicheskoi prochnosti granul i nizkoi udel'noi poverkhnosti
