    Abstract: The invention realizes a catalyst which is hardly deteriorated even when volatile catalyst-poisoning compounds such as P and As are accumulated and which can reduce the rate of oxidation of SO2 to a level as low as a fraction of that of the catalyst in the prior art, and provides an exhaust gas purification catalyst which can maintain a high activity and a low rate of oxidation of SO2 for a long time even with any diversified coal, a method of producing the same, and an exhaust gas purification method using the same. Disclosed is an exhaust gas purification catalyst having a composition comprising oxides of titanium (Ti), molybdenum (Mo) and/or tungsten (W), vanadium (V) and bismuth (Bi), wherein the atomic ratio of Ti:(Mo and/or W):V is 75 to 98.9:1 to 0.1 to 10 and the atomic ratio of Bi/(Mo and/or W) is 0.1 to 0.8.

    Abstract: The present invention relates to a cobalt/phosphorus-alumina catalyst in which cobalt is supported as an active component on a phosphorus-alumina support wherein phosphorus is supported on alumina surface. With a bimodal pore structure of pores of relatively different pore sizes, the catalyst provides superior heat- and matter-transfer performance and excellent catalytic reactivity. Especially, when Fischer-Tropsch (F-T) reaction is performed using the catalyst, deactivation by the water produced during the F-T reaction is inhibited and, at the same time, the dispersion and reducing property of cobalt and other active component are improved. Therefore, the cobalt/phosphorus-alumina catalyst for F-T reaction in accordance with the present invention provides good carbon monoxide conversion and stable selectivity for liquid hydrocarbons.
