An Investigation into the Effects of Mn Promotion on

Mn is an effective promoter for improving the activity and selectivity of Co-based FischerTropsch synthesis (FTS) catalysts, but the mechanism by which this promoter functions is poorly understood. The work reported here was aimed at defining the manner in which Mn interacts with Co and determining how these interactions affect the activity and selectivity of Co. Detailed measurements are Investigation of the promoting effect of Mn on a Pt Abstract The catalytic performances in steam reforming (SR) and aqueous phase reforming (APR) of glycerol of a bimetallic Pt-Mn catalyst supported on activated carbon are investigated and correlated with the surface properties of the catalyst. Under SR conditions, Mn showed a significant promoting effect over Pt/C, both in terms of hydrogen production rate and conversion, with a higher

(PDF) INVESTIGATION OF THE BORON EFFECT ON THE HIGH

The base alloy had 0.04%C, 1.5%Mn and 0.31% Si, and four different levels of boron (between 29 and 105 ppm). This analysis is based in obtaining hot ductility and flow curves. Hot tensile tests were carried out at different temperatures (700, 800, 900 and 1000ºC) at a constant true strain rate of 0.001 s 1 .

Investigation of the promoting effect of Mn on a Pt/C

Request PDF Investigation of the promoting effect of Mn on a Pt/C catalyst for the steam and aqueous phase reforming of glycerol The catalytic performances in steam reforming (SR) and aqueous Molecules Free Full-Text Pt-Au/MOx-CeO2 (M = Mn, Fe A series of nanostructured Pt-Au/MO x -CeO 2 (M = Mn, Fe, Ti) catalysts were prepared and their catalytic performance for the co-oxidation of carbon monoxide (CO) and hydrogen (H 2) were evaluated at room temperature. The results showed that MO x promoted the CO oxidation of Pt-Au/CeO 2, but only the TiO 2 could enhance co-oxidation of CO and H 2 over Pt-Au/CeO 2. Noble Metal Promoted CoMn Catalysts for FischerTropsch Feb 05, 2018 · Characterisation and testing found promotion to increase catalyst activity without compromising the selectivity promoting effects of Mn. The noble metal promoted catalysts showed olefin and C 5+ selectivities that were slightly increased compared to the unpromoted catalysts indicating some degree of influence on the selectivity.

Promoting Effect of Ce in Ce/OMS-2 Catalyst for Catalytic

Nov 09, 2010 · On the other hand, no cerium oxide phases on the Ce/OMS-2 were detected after the thermal treatment, while a weak peak of Mn 2 O 3 phase at 33.0 o was detected when the Ce/Mn ratio was larger than 0.05. The intensity of Mn 2 O 3 increased with increasing Ce/Mn ratio until 0.07. When the Ce/Mn ratio was higher than 0.07, the intensity slightly decreased. Pt/CLiCoO2 composites with ultralow Pt loadings as Feb 22, 2016 · As shown in Fig. 2e, a significant improvement in mass activity was observed for the PtLiCoO 2 (1 :49) catalyst (2.04 A mg Pt 1) in comparison with the benchmark Pt/C (0.095 A mg Pt 1) at 0.8 V, which was almost 21 times higher than the corresponding value of Pt/C. The promoting effect of noble metal (Rh, Ru, Pt, Pd Noble metal (Rh, Ru, Pt, Pd) doped MnOxCeO 2 /graphene catalysts were prepared by a hydrothermal method, which exhibited promoting effects on the selective catalytic reduction (SCR) of NO with NH 3 at low temperatures. The catalytic activity test results suggested that MnOxCeO 2 Pd/GR exhibited the best catalytic performance. Moreover, the addition of Pd to MnOxCeO 2 /GR enhanced
