Titania supported ruthenium as a coking-resistant catalyst for high pressure dry reforming of methane

Effective utilization of waste: development of CH4 dry reforming catalysts from spent nickel metal hydride battery for resource recovery

“…As the estimation indicates that the temperature range from 700 to 835 °C is appropriate for the CH 4 dry reforming, the reaction temperature was decided on 780°C in the present study. This temperature is consistent with those reported by a lot of researches [4,5,7,8,14]. Figure 4 shows the CH 4 conversion over NiO prepared from the anode material as a function of reaction time.…”

“…It has been known that noble metal (Pt, Rh, Ru, Pd and Ir) supported catalysts had good catalytic performance for the CH 4 dry reforming [1][2][3][4][5][6][7][8][9]. However, the development of cheap metal catalyst has been desired, because the noble metal catalyst is not suitable for utilizing on a large scale.…”

Energy efficient methane tri-reforming for synthesis gas production over highly coke resistant nanocrystalline Ni–ZrO2 catalyst

“…10). The conversion of reactants and selectivity of the products was dependent on number of active sites, size of the active metal (Ni) and the reducibility of the active (Ni) species [59,60,66,[73][74][75][76]. With increasing wt% of Ni loading Ni dispersion was increased upto 3.0 wt% Ni but above that the Ni dispersion was found to be decreasing.…”

Effect of Ce/Ti ratio on the catalytic activity and stability of Ni/CeO2–TiO2 catalyst for dry reforming of methane

“…A number of studies have claimed that the nature of the support strongly affects the catalytic behavior and carbon deposition during methane dry reforming [15][16][17][18][19][20]. The supports that have been explored in an effort to enhance catalyst performance and control carbon deposition are alumina, SiO 2 , ZrO 2 , and TiO 2 .…”

“…The supports that have been explored in an effort to enhance catalyst performance and control carbon deposition are alumina, SiO 2 , ZrO 2 , and TiO 2 . Among these, TiO 2 has been reported to be an excellent support for suppressing carbon deposition [15][16][17][19][20][21][22][23][24][25][26]. The TiO x species partially reduced by H 2 treatment, the pre-treatment for catalyst activation, migrate to metal particles, and then provide Me-O v -Ti 3+ sites.…”
