الملخص

يتناول هذا البحث تصنيع الزركونيا المكبرتة باعتبارها كعامل مساعد حامضي ناجح بطريقة الترسيب و التشريب, العامل المساعد المصنع تم توصيفه بواسطة التحليل الطيفي للاشعة تحت الحمراء XRD، الاشعة السينية FTIR، تحليل المساحة السطحية BET، المسح الالكتروني المجهري FESEM. يتم ترسيب الانابيب النانوية الكاربونية على سطح الزركونيا المكبرتة اثناء التصنيع وتظهر النتائج ان اضافته تزيد من المساحة السطحية للزركونيا المكبرتة من 80.2 م2\غم الى 87.74 م2\غم، اظهرت زيادة معقولة بحجم المسامة وصل الى 0.0936 سم³\غم، اعطى توزيع اضيق مع تقليل لقطر المسامة ليصل الى 3.2417 نم، واعطى حجم كرستالي اقل 10.5 نم، بينما الزركونيا المكبرتة اعطت حجم كرستالي 11.06 نم، حجم بور 0.0789 سم3\غم ومعدل قطر المسامة كان 3.9682 نم. بينما اظهرت النتائج ان الزركونيا المكبرتة بدون اضافة الانابيب النانوية الكاربونية هي اكثر ملائمة لعملية الازمرة لان المجاميع الفعالة فيها اعلى كما ظهر في تحليل الاشعة السينية ال FTIR. ان العامل المساعد المحضر بكميات وزنية متساوية من الزركونيا المكبرتة و الزيولايت نوع HY اعطى اعلى قيمة لتحول النفثا الخفيفة بعملية الازمرة هي 70,76 مول % عند حرارة 160 درجة سيليزية و ضغط 15 بار و 1 ساعة^-1.
