Kinetic study of upgrading extra-heavy oil in supercritical water conditions with and without a zinc nitrate precursor was investigated. Reactions were carried out at 653 K, 673 K, 693 K, and 713 K in a batch reactor. Kinetic parameters including reaction rate constants were calculated based on a phase separation kinetic (PSK) model. Compared to pyrolysis, the rate of maltene decomposition and solubility limits were significantly low. Addition of the zinc nitrate precursor changed the amount of volatile from reacted maltene and the amount of coke from excess asphaltene cores. Coke induction period where coke formation is suppressed was obtained. Maltene selectivity was calculated based on the amount of maltene and volatile and the highest maltene selectivity value was 6.96 at 693 K, without the zinc nitrate precursor.

研究了在有和没有硝酸锌前体的情况下在超临界水条件下提质超重油的动力学研究。反应在间歇反应器中以653 K，673 K，693 K和713 K进行。基于相分离动力学（PSK）模型计算包括反应速率常数在内的动力学参数。与热解相比，丙二烯的分解速率和溶解度极限非常低。硝酸锌前体的添加改变了反应后的丙二烯的挥发物量和过量的沥青质核的焦炭量。获得了抑制焦炭形成的焦炭诱导期。根据麦芽和挥发物的量计算出麦芽烯的选择性，在没有硝酸锌前体的情况下，最高的麦芽烯选择性在693 K时为6.96。
