“…Different precipitating agents have been employed for the common precipitation route, e.g. sodium carbonate [12][13][14][15][16][17][18][19], sodium aluminate [20] and oxalic acid [21][22][23][24][25]27]. Furthermore, the influence of preparation parameters, such as addition rate of the precipitating agent, temperature, pH [12,16,17] and the effect of calcination and reduction conditions [18,24] have been thoroughly investigated.…”

“…Este sistema catalítico tem atraído grande interesse acadêmico na elucidação da sua preparação, em especial da etapa de co-precipitação na qual importantes mudanças físico-químicas ocorrem, tais como a formação de diferentes fases de carbonatos, hidróxidos e hidroxicarbonatos, a depender das condições de preparação 1,3,4 . O processo de preparação do catalisador CuO/ZnO/M 2 O 3 (M = Al, Cr) é representado na Figura 1 através de um diagrama de causa e efeito, no qual as principais etapas da preparação juntamente com as suas variáveis são apresentadas.…”

“…Different catalysts have been developed for WGS reactions, including Fe-Cr based high temperature catalysts, Cu-Zn-Al based low temperature catalysts and Co-Mo based sulfur-tolerant catalysts [26,27]. Co-Mo catalyst can be used in a wide range of temperature.…”
