A series of 40% Ni/Ce_xCr_1-xO₂ catalysts with x = 0, 0.1, 0.3, 0.5, 0.9 and 1 were synthesized using one-pot hydrolysis method as catalysts for the methanation process. The reaction was carried out in a packed-bed and micro-channel reactors. 40 wt% Ni/Ce_0.5Cr_0.5O₂ showed the best catalytic performance towards the methanation process at 270 °C, giving 92.63% of CO₂ conversion and 90.53% of CH₄ yield. The catalyst exhibited great stability after 50 h of time-on-stream with carbon deposition around 0.0056 mg h⁻¹ was observed. The micro-channel reactor showed better performance than the packed-bed reactor in term of methane production rate which offered amount of methane production rate 109.1 mL min⁻¹ gcat⁻¹ which nearly 8 times greater than that packed-bed reactor.

使用一锅法水解法合成了一系列x = 0、0.1、0.3、0.5、0.9和1的40％Ni / Ce _x Cr _1-x O ₂催化剂作为甲烷化过程的催化剂。该反应在填充床和微通道反应器中进行。40 wt％Ni / Ce _0.5 Cr _0.5 O ₂在270°C下对甲烷化过程显示出最佳的催化性能，可实现92.63％的CO ₂转化率和90.53％的CH ₄产率。催化剂在运行50小时后表现出很高的稳定性，碳沉积量约为0.0056 mg h ^-1被观测到。就甲烷产生速率而言，微通道反应器表现出比填充床反应器更好的性能，其提供的甲烷产生速率的量为109.1mL min ^-1 gcat ^-1，是填充床反应器的近8倍。
