In line with Egypt’s vision for 2030 and the global trend towards a green and sustainable environment. This thesis focuses on refining waste lubricating oil using the acid/clay method involving H2SO4. The goal is to compare the refined oil characteristics with the Egyptian standards while applying zero waste discharge. Additionally, the thesis aims to improve oil characteristics by adding jojoba oil in varying percentages. Subsequently, the refined oil was tested in a car engine to ensure that its performance was comparable to the commercial oil.
تماشياً مع رؤية مصر 2030 والتوجه العالمي نحو بيئة خضراء ومستدامة، تركز هذه الأطروحة على تكرير زيوت التشحيم المستعملة باستخدام طريقة الحمض/الطين التي تتضمن H2SO4. والهدف هو مقارنة خصائص الزيت المكرر بالمعيار المصري مع تطبيق مبدأ عدم وجود نفايات. بالإضافة إلى ذلك، تهدف الأطروحة إلى تحسين خصائص الزيت عن طريق إضافة زيت الجوجوبا بنسب متفاوتة. بعد ذلك، تم اختبار الزيت المكرر في محرك سيارة للتأكد من أن أدائه قابل للمقارنة بالزيت التجاري.
