摘　　要：超临界多元热流体(scMTF)组分含量特征受不同因素的影响,目前其影响规律不明。为此,通过文献研究获得大量超临界水环境下的有机物气化产物数据,基于这些数据分析scMTF组分含量与其相关因素的关系。研究发现:1)反应原料类型和反应温度对scMTF组分含量的影响有一定关联。对于不同类型原料,分子量越大越难以裂解,当反应温度低于使原料完全裂解的温度阈值时其影响显著,反之则其影响大幅减弱;对于同类型原料,当反应温度低于某一阈值时其影响显著,而高于此阈值时其影响大幅减弱。2)原料质量分数、反应压力、反应时间和催化剂类型对scMTF组分含量的影响规律不统一,甚至相互矛盾。3)催化剂质量分数对scMTF组分含量的影响甚微。The component content characteristics of supercritical multi-thermal fluid(scMTF)are impacted by different factors,but its influence law has been unknown so far.Therefore,a large amount gasification products data of organic matter in supercritical water environment was collected through literature research,based on which the component contents of thermal fluid components under different reaction conditions were calculated,and the effects of different factors on the component content characteristics were compared from many aspects.The change law of the component content with the reaction conditions was studied.Results show that:1)There exists a certain correlation between the reaction material type and reaction temperature on the component contents of scMTF.For different types of raw materials,the larger the molecular weight of the reactant is,the more difficult it is to crack.For the same type of raw materials,if the reaction temperature is lower than the temperature threshold for complete cracking of raw materials,the effect is significant,and,and vice versa-if above this threshold,the effect is significantly weakened.2)The influence law of the mass concentration of raw materials,reaction pressure,reaction time and catalyst type on scMTF component content is inconsistent and even contradictory.3)It has little effects on the mass concentration of catalyst.
