التنشيط الكيميائي للكوك النفطي بالصهر البوتاسي

Abstract EN

Petcoke from refineries were activated by alkaline fusion.

Chemical activation by potassium hydroxide and sodium hydroxide at low temperature under ambient atmosphere were performed.

The results show that the chemical activation by potassium hydroxide gives the higher surface area and lower particles zise.

The effect of the ratio of potassium hydroxide to coke was studied and the ratio of 6:1 was found to be the best and gives the maximnm surface area (1500m2/g).

The decreasing in the metals content in the activated coke was noticed and FTIR spectrum identified the increasing of oxygen content on the surface of activated coke.

The X-ray diffraction indicated that a disorder occurred after activation process and the P63 space group C8 with cubic crystallized structure.
