The successful application of zeolites in diverse fields largely relies on their high stability, unique catalytic activity, and adsorptive properties. However, the property requirements for zeolites have become severe due to their diverse and demanding applications. Novel post-synthetic treatment of zeolites show that properties of zeolites can be tuned by simple liquid-mediated treatments, in which new concepts such as pore-filler stabilization and pore-opening migration have been proposed. For example, development of extremely stable zeolites that can withstand over 1000°C steaming and dealumination of small-pore zeolites, which had been believed to be impossible, were reported and further superior zeolite-based catalysts with longer catalytic life and/or improved selectivity have been realized.

CO2 methanation is a technology that produce CH4 using CO2 and H2 as raw materials through the Sabatier reaction. In the present study, the effects of temperature characteristics and CO2 conversions in the two types of catalyst reactors (i.e., granular catalyst reactor, catalyst coated reactor) were evaluated. For the catalyst coated reactor, the base substrate was formed to a circular tube composed of agglomerates of metal particles by the Additive Manufacturing method. The catalyst layer was produced by the slurry coating method. The fine particles in the slurry were obtained by pulverizing the commercially catalyst with a hammer mill. The thickness of the catalytic particle layer was increased by multiple coating process, and the catalyst base-substrate was not exposed. The temperature rise of nearly 50°C occurred in the granular catalyst reactor at a set temperature of 300°C, while in the coated catalyst reactor the temperature was almost flat along the gas flow direction. Furthermore, it was clarified that the CO2 conversions were determined by the maximum temperatures of the catalyst reactors. The proposed reactor in this study showed the possibility for solving the problem in the methanation process that is the temperature rises during the reaction.
