As results, API of liquid product increases but the liquid yield decreases with increasing conversion due to the higher formation of gas and coke. Compared to the reaction at a lower temperature with longer time, the one at a higher temperature with short time showed a slightlyÂ better liquid yield, API improvement and MCR removal keeping the low hydrogen consumption but the sulfur and metal removals are inferior relatively at the same conversion. When the concentration of catalyst increases, the improvement of conversion was prominent at the low temperature. API increment and desulfurization was higher than that at low concentration of catalysts. Asphaltene in the liquid phase was analyzed in terms of colloidal stability so that it was shown to be worse with increasing the conversion. Based on the ratio of iC4 to nC4 in the gas products, the characteristics between thermal and catalytic cracking was compared with the change of conversion.
