Light naphtha is one of the products from distillation column in oil refineries used as feedstock for gasoline production. The major constituents of light naphtha are (Normal Paraffin, Isoparaffin, Naphthene, and Aromatic). In this paper, we used zeolite (5A) with uniform pore size (5A) to separate normal paraffin from light naphtha, due to the suitable pore size for this process and compare the behavior of adsorption with activated carbon which has a wide range of pores size (micropores and mesopores) and high surface area. The process is done in a continuous system-Fixed bed column-at the vapor phase with constant conditions of flow rate 5 ml/min, temperature 180 o C, pressure 1.6 bar and 100-gramweight of each adsorbent according to many other experiments on zeolite (5A) and choose the best conditions for comparison. The molecular sieve (5A) separated the normal paraffin (C 4 -C 8 ) from light naphtha feed with highest percentage removal reaching a (92.36 %) at the beginning of the process. Activated carbon separated naphthene and aromatics with highest percentage removal reaching a (95.3 %) for naphthenes and a (100 %) for aromatics at the beginning of the separation process. The study shows the difference in physical adsorption behavior and the effect of pore size on these processes.

The study included the use of two path in the process of preparation.The first pathway included preparation of the AC from Baiji asphalt by an oxidation process done at 350 °C using 2% FeCl 3 for 3hours, after that the resulting product was distillated normal and vacuum distillation, and then the resulted of vacuum distillation were carbonized at a temperature of 400°C for 2hours and treated with KOH at various ratios ranging from (0.5:1) ,(1:1) and(2:1) (potassium hydroxide: carbonized materials) using microwave radiation at power of

Praise be to Allah, and prayers and peace be upon our master Muhammad, the Messenger of  Allah , and his family and companions and those who follow him, and after: This research aims to explain the impact of the difference of jurists, may  Allah  Almighty have mercy on them, in the verses of rulings contained in Surat Al-Kahf, the issues of the orphan as a model, and the interpretation of the verses of rulings is characterized by that it contains Benefits in various sciences, as it includes the sciences of the Qur’an, the science of jurisprudence and its origins, the science of education and behavior, and the general meanings of the Qur’anic verses. And comment and weighting as required by the place. And that Surat Al-Kahf included many jurisprudential rulings, which the jurists derived from its noble verses, and among these are the issues and rulings of the orphan. And some provisions contained in the Holy Surah.
