    Abstract: PURPOSE: A water gas converting chrome-free-based catalyst containing alkali metals is provided to efficiently eliminate carbon monoxide and to suppress the generation of methane in a water gas converting reaction by being composed of iron, nickel, and alkali metals. CONSTITUTION: A water gas converting chrome-free-based catalyst is a chrome-free complex catalyst which is obtained by carrying alkali metals in a catalyst composed of iron and nickel. The contents of iron and nickel are respectively between 55 and 85 weight% and between 15 and 45 weight% in the catalyst. The contents of iron, nickel, and the alkali metals are respectively between 60 and 80 weigh%, between 15 and 35 weight%, and between 1 and 10 weight%. The alkali metals are potassium or cesium. The catalyst eliminates carbon monoxide and suppresses the generation of methane after the vapor modification of liquefied natural gas.

    Abstract: 본발명은알칼리금속을함유하는비-크롬계수성가스전환반응용촉매에관한것으로, 더욱구체적으로수성가스전환반응용촉매에있어서, 철과니켈로구성된촉매에알칼리금속이담지되고크롬을함유하지않는복합촉매인것을특징으로하는수성가스전환반응용촉매에관한것이다. 본발명에따르면, 철, 니켈및 알칼리금속으로구성되는촉매는탄화수소류연료의수증기개질반응을통하여생성된일산화탄소의제거를위한수성가스전환반응에서기존의크롬계촉매보다더 높은일산화탄소제거효과를보이며촉매내 크롬및 귀금속이포함되어있지않아안전하고경제적이다. 또한, 수성가스전환반응에서생성될수 있는메탄의생성억제에도효과가있다.
