    Abstract: Embodiments described herein generally relate to a composite carbonate utilized as a catalyst in coal gasification processes. Methods described herein also include suitable processing conditions for performing coal gasification with the composite catalyst. In certain embodiments the composite catalyst may comprise an alkali carbonate and a transition metal carbonate, for example, an FeCO3—Na2CO3 catalyst. An FeCO3—Na2CO3 catalyst, compared to raw coal, may increase the carbon conversion rate by about two times within the 700° C-800° C. range due to its ability to reduce the activation energy of gasification by about 30-40%. Compared to pure sodium and pure iron catalysts, the composite catalyst may increase the yields of desired products H2 and CO at 800° C. by 14.8% and 40.2%, respectively.

    Abstract translation: 本文所述的实施方案通常涉及用作煤气化过程中的催化剂的复合碳酸盐。 本文所述的方法还包括用复合催化剂进行煤气化的合适的加工条件。 在某些实施方案中，复合催化剂可以包含碱金属碳酸盐和过渡金属碳酸盐，例如FeCO 3 - Na 2 CO 3催化剂。 与原煤相比，FeCO3-Na2CO3催化剂可以在700°C-800°C范围内将碳转化率提高约两倍，这是由于其将气化活化能降低约30-40％的能力。 与纯钠和纯铁催化剂相比，复合催化剂可以将所需产物的H 2和CO在800℃下的产率分别提高14.8％和40.2％。
