الملخص

في هذه الدراسة، تم دمج عمليتي الاستحلاب والامتزاز لازالة الكبريت من وقود الديزل لمصفى البصرة. تم تقييم مواصفات الديزل المحسن المستخرج من هاتين العمليتين والبديلة لعملية الهدرجة باستخدام العامل المحفز حيث تم تحسين خصائص الديزل باستخدام تقنية التصميم التجريبي (طريقة احصائية)RSM. تم إجراء 20 تجربة مختبرية في كل عملية. تمت أكسدة وقود الديزل عالي الكبريت بنسبة 1.4538% نسبة وزنية من مصفى البصرة بشكل فعال باستخدام H₂O₂ وحمض الأسيتيك (AcOH) كعامل محفز لتقليل محتوى الكبريت إلى 1.0875% نسبة وزنية قبل دخوله الى عملية استحلاب. تم ادخال وقود ديزل مصفى البصرة المؤكسد ذو المحتوى الكبريتي 1.0875% وزنا الى عملية الاستحلاب. تم دراسة تأثير إزالة الكبريت بواسطة الاستحلاب على وقود الديزل المؤكسد باستخدام خافض الشد السطحي ألكيل بنزين سلفونيت. تم تحقيق نسبة كبريت للديزل 0.83886% وزنا في الظروف المثلى التالية: تركيز الكيل بنزين سلفونيت 20% وزنا، درجة الحرارة 57.56 درجة مئوية ، وسرعة الخلط المتجانس 5695 دورة في الدقيقة. تم ادخال الديزل الناتج من عملية الاستحلاب الى عملية الامتزاز باستخدام طين البنتونايت المنشط في نظام الدفعات. تم تطبيق تقنية التصميم التجريبي (RSM) لتحديد تأثير زمن التلامس (1-10 ساعة) وكتلة الطين (5- 20 جم / 50 مل) ودرجة الحرارة (30-100 درجة مئوية) على إزالة الكبريت. أظهرت النتائج أن محتوى الكبريت 0.57% وزنا قد تحقق في الظروف التالية: زمن الامتزاز 7.18 ساعة ودرجة الحرارة 53.3 درجة مئوية وكتلة الطين 15.24 غم / 50 مل. تمت دراسة جودة وقود الديزل بواسطة تحاليل GC وIREX .
