TL;DR: In this paper , the structural effect of the Ni/TiO2 catalyst on CO methanation was investigated, and it was shown that the Ni particle size and higher Ni dispersion improved coke resistance and enhanced anti-sintering ability.
Abstract: CO methanation over a supported Ni catalyst has attracted increasing attention for its applications in synthetic natural gas production, CO removal for ammonia synthesis and fuel cells, among others. However, the deactivation of the Ni catalyst caused by sintering and carbon deposition hinders further application of the Ni catalyst. The activity of Ni catalysts needs further improvement as well. In this work, the structural effect of the Ni/TiO2 catalyst on CO methanation was investigated. A plasma decomposition, initiated at room temperature and operated around 150 °C, of the nickel precursor was applied to prepare the catalyst. Compared to the thermally decomposed Ni/TiO2 catalyst, the plasma-decomposed catalyst shows improved activity with enhanced stability. The catalyst characterization shows that the plasma-decomposed Ni/TiO2 catalyst possesses smaller Ni particle size and higher Ni dispersion, resulting in improved coke resistance and enhanced anti-sintering ability for CO methanation. The present study confirms that a catalyst with good activity for CO methanation possesses good activity for CO2 methanation as well, if the CO2 methanation takes the CO methanation pathway.

TL;DR: In this article, a novel methanation catalyst consisting of an active component, a carrier, a first auxiliary, and a second auxiliary was proposed for producing synthetic natural gas from coal gas at high temperature and high pressure.
Abstract: The present invention discloses a novel methanation catalyst and a preparation method thereof, which can solve the problems that a current high temperature resistant methanation catalyst comes mainly from import, and the price of the methanation catalyst is high, but the high temperature resistant methanation catalyst is urgently required in China. The novel methanation catalyst comprises an active component, a carrier, a first auxiliary, and a second auxiliary. The raw materials and the preparation method of the catalyst are obviously different from those of the prior art, the novel catalyst can be used for producing synthetic natural gas from coal gas at high temperature and high pressure, and be used for methanation preparation of gas rich in CO, CO2 and H2. The catalyst comprises the active component, the carrier, the first auxiliary and the second auxiliary, is suitable for production of synthetic natural gas from coal gas at high temperature and high pressure, is high in high-temperature activity, stability and carbon deposit prevention so as to fully satisfy the production requirements of high temperature resistant methanation catalysts and has important significance in domestication of similar catalysts and reduction of production costs.
