الملخص

     يتعامل هذا العمل مع تحضير عامل مساعد مركب (Pt / HY-H-Mordenite) لأزمرة النفثا الخفيفة العراقية المنتجة من مصفاة بيجي الشمالية في مفاعل بطبقة ثابتة في وحدة تجريبية تحت ظروف التشغيل بالنطاقات التالية: درجة الحرارة 150-250 درجة مئوية، سرعة السائل الفراغي 2.46-4.7 ساعة-1، الضغط 6 بار، ونسبة الهيدروجين إلى الهيدروكربون 3.7 مول / مول. تم فحص المحفزات المحضرة مختبريا ومنها نانوسيليكا، Na-موردينايت، H-موردينايت، وPt / HY-H-موردينايت، بواسطة حيود الأشعة السينية (XRD)، الفحص المجهري الإلكتروني لمسح الانبعاث الميداني ((FE-SEM، مطيافية الأشعة تحت الحمراء لتحويل فورييه (FTIR)، وتحليل المساحة السطحية (BET). أظهرت نتائج البحث أن نسبة تحويل أزمرة النفثا الخفيفة وزيادة الإنتاجية تزداد مع ارتفاع درجة الحرارة وانخفاض سرعة السائل الفراغية. اعلى تحول وانتاجية تم الحصول عليها عند 250 درجة مئوية وسرعة السائل الفراغي2.46 ساعة -1 والتي هي 89.38٪ و76.36٪، على التوالي.
