Abstract. Ni catalysts promoted with 0.5 and 1.0 wt% boron were synthesized, characterized and tested during steam methane reforming, to evaluate the effect of boron on the deactivation behavior. Boron adsorbs on the γ -Al2O3 support and on the Ni particles and 1.0 wt% boron is found to enhance the stability without compromising the activity. Catalytic studies at 800 ◦C, 1 atm, a stoichi…
Abstract. The liquid-phase hydrogenation of citral was studied at 393 K and 10 bar on Pt–Co/C catalysts, having different Pt/(Pt + Co) ratios and containing a total metal load of about 2%. The monometallic and bimetallic Pt–Co/C catalysts were prepared by impregnation and co-impregnation, respectively, with cobalt tris(acetylacetonate) and platinum bis(acetylacetonate). Monometallic Pt/…
