Experimental Study of the Effects of Heating Type on the Oil Produced from Iranian Oil Shale Samples

This study investigates and evaluates the effects of heating type using microwaves and conventional heating on the yield and quality of oil-shale produced from the Qalikuh reservoir with total organic carbon TOC between 3.83 and 26.4% by the weight and average  16.5% by weight. With microwaves heating, Maximum oil produced is %5.9 by weight and  Based on the analysis of SARA shale oil compounds, asphaltene compounds decrease (24% by weight), saturated compounds increase (on average 40% by weight), and resinous and aromatic compounds also have fluctuating behavior. In conventional heating, Maximum oil Produced is 4.5% by weight, and  the amounts of saturated compounds (about 23% by weight) and asphaltic compounds (on average 14% by weight) in shale oil decrease, but resinous compounds (about 28% by weight) decrease and compounds Aromatic values also fluctuate. The highest desulfurization in shale oil produced using microwaves was observed, The amount of nitrogen in the shale oil also decreases with the heating by microwaves finally reaches to 8% by weight. In shale oil produced by normal heating, finally sulfur decreases by 31%, nitrogen increases by 21%, and oxygen increases by 60%.
