Literature on COS hydrolysis research has been concentrated on kinetics of the catalyst or the reaction mechanism thereof. [PERSON] et al. performed extensive studies on kinetics and relevant mechanistic experiments using an alumina catalyst to determine COS hydrolysis performance [1]. [PERSON] et al. evaluated characteristics of a zinc-promoted alumina catalyst at 150 \({}^{\circ}\)C instead of the alumina catalyst of the previous paper [2; 3]. [PERSON] et al. analyzed the COS hydrolysis mechanism of alumina using infrared spectroscopy and a quantum chemistry calculation [4]. [PERSON] evaluated activity using various promoters (Na, Fe, Co, Cu, Ni, Zn) of \(\gamma\)-Al\({}_{2}\)O\({}_{3}\) catalyst, and Ni and Zn were found to have the best properties [5]. [PERSON] et al. investigated catalytic activity of various oxide catalysts (Z\({}_{\text{r}}\)O\({}_{2}\), TiO\({}_{2}\), Al\({}_{2}\)O\({}_{3}\)) [6]. [PERSON] et al. also performed COS hydrolysis studies, especially related to its advancement on catalytically active areas of alkali metal oxides at 45-100 \({}^{\circ}\)C [7]. [PERSON] et al. studied how to improve catalytic activity of Al\({}_{2}\)O\({}_{3}\) under low humidity conditions as well as how to remove COS by adsorption [8]. Similar adsorption of COS on activated carbon was also investigated by [PERSON] et al. [9; 10]. They also efficiently performed COS removal using a metallic catalyst and activated carbon. [PERSON] et al. evaluated adsorption and desorption of low concentrations of carbonyl sulfide by impregnating active carbon [11]. [PERSON] et al. investigated the effects of catalyst composition on catalytic hydrolysis of COS [12]. [PERSON] et al. evaluated the effects of Fe/Cu/Ce loading on the coal-based activated carbons for COS hydrolysis [13]. [PERSON] et al. performed a study on catalytic hydrolysis of carbonyl sulfide and carbon disulfide over an Al\({}_{2}\)O\({}_{3}\)-K/CAC catalyst at low temperature [14]. COS hydrolysis using noble metal catalysts was also performed by [PERSON] et al. [15] and [PERSON] et al. [16] who evaluated the catalytic removal efficiency of such noble metal catalysts. In the previous studies, the kinetics of the COS reaction catalysts or catalytic activation for the improvement of efficiency were mainly studied. However, in order to design an actual plant, evaluation data on the design parameters of the plant are needed. To evaluate the effect of design parameters, a detailed analysis model considering chemical kinetics as well as thermal-fluid flow of the COS reactor is required. Eventually, design direction can be presented through comprehensive evaluation in terms of heat and mass transfer. In this study, the COS hydrolysis reactor, which is an acidic gas removal system of an Integrated Gasification Fuel Cell system, performed the following procedure to predict the probabilistic performance change with various design parameters (space velocity, length ratio, and temperature per gas hour).
