摘　　要：为了使催化剂在化学反应加热提高采收率(CHEOR)技术中更为可靠、高效,研究了利用钴基和铁基催化剂作为CHEOR技术中定向化学反应的催化剂新方法。该方法通过一维模拟实验,在多孔介质中对化学反应生热状况进行了研究。结果表明,多孔介质中纳米钴基、铁基催化剂均能催化化学反应。在298℃、1 MPa条件下,化学反应释放的热量最高可将多孔介质中的温度升高48℃;当合成气注入流量为400 mL/min时,铁基催化剂催化化学反应能够持续稳定释放热量,但在含油多孔介质中,铁基催化剂的活性会受到影响。研究结果表明,纳米催化剂的反应生热技术在多孔介质中的可行性,同时为后续催化剂的研制及参数选择提供了依据。In order to make catalysts more reliable and efficient in chemical reaction heat enhanced oil recovery(CHEOR)technology,a new method using cobalt based catalysts and iron based catalysts as catalysts for directional chemical reactions in CHEOR technology is developed.The results show that both cobalt-based catalysts and iron-based catalysts can catalyze chemical reactions in porous media.Under the condition of 298℃and 1 MPa,the heat released by chemical reactions can raise the temperature in porous media by up to 48℃.When the syngas injection flow rate is 400 mL/min,iron-based catalysts can continuously release heat after catalyzing chemical reactions.However,in oil-bearing porous media,the activity of iron-based catalyst will be affected.The results of this study demonstrate the feasibility of reaction heat generation technology based on nanocatalyst in porous media,and provide a basis for the development of subsequent catalysts and injection parameters control.
