Fundamental studies on thermal cracking have deen done to get low-sulfur fuels from petroleum residue.
Vacuum bottom and propane deasphalten were converted with batch reactor to gases, oil and coke in the temperature range of 500°C-800°C.
As the temperature rose, the coke yield decreased and the liquid yield increased sharply up to 700°C, and they scarcely changed above 700°C. Gas yield increased slightly as the temperature rose.
Sulfur yield showed the same tendency with the product distribution, but sulfur yield to gas did not change above 600°C.
CaO, MgO and dolomite were added to the feed stock and they reacted with H2S during the reaction. Among them, CaO was found to be the best effective desulffurizer at 800°C.
