Abstract
Engil olefinlar, shu jumladan etilen, propilen, butenlar va butadienlar kimyo sanoatida
polimerlar, erituvchilar, qurilish, sintetik tolalar va boshqalar ishlab chiqarish uchun
ishlatiladigan asosiy qurilish bloklaridir [1-6]. Etilendan polietilen, polivinilxlorid va
boshqalar ishlab chiqarish uchun foydalanish mumkin. Polietilenga talab ortib borishi
munosabati bilan etilen ishlab chiqarish 2017-yildagi 169 million tonnadan, 2023-yilda 230
million tonnagacha oshishi kutilmoqda. Propilen polipropilen, akrilonitril va boshqalar,
ishlab chiqarish uchun ishlatiladi [7-11]. Yillik buten ishlab chiqarish 132million tonna
atrofida bo'lib, ular orasida izobuten asosan alkilatlar ishlab chiqarish uchun xom ashyo
sifatida ishlatiladi [12-17].
