The effect of gaseous carbon monoxide on the hydrogenation of acetylene over Ni supported on MgAl 2 O 4 in the presence and absence of zinc dopants has been investigated. Both carbon monoxide and zinc inhibit activity to a considerable extent. Carbon

A literature proposal that the reduction of nitrous oxide by carbon monoxide over rhodium catalysts proceeds by cleavage of the N N bond has been tested through the use of 15N14NO as the reactant. The results disprove the suggestion in that 14N15N is

The generation of essentially pure hydrogen through a redox cycle using methane and then water has been investigated for a series of tungsten oxides stabilised by ceria–zirconia. The calcined starting materials were largely monoclinic WO3 with CeO2

The effect of small amounts of carbon monoxide on the oligomerization of acetylene over a low loaded Ni/SiO 2 catalyst has been investigated. Although CO does not participate in the reaction it has two beneficial effects if oligomer products are desi

The characteristics of nickel on silica catalysts for the reaction of acetylene in the presence of hydrogen in a flow system are investigated. Samples containing 2 wt% Ni are capable of complete acetylene conversion over a period of 5 h at 140 °C wh

Here we compare the uptake of CO 2 on BaO–Al 2 O 3 with that of NO 2 for nine samples made by one, two or three incipient wetness impregnations using acetate and nitrates as the precursor salts. The amounts of CO 2 and NO 2 adsorbed to the point of

Nickel–tungsten-based hydrotreating catalysts have been prepared with different metals impregnation profiles and tested for the hydrodesulphurisation, hydrodenitrogenation and hydrogenation of model compounds. Penetration of the catalyst by the mod

In this study, we compared the NO x storage reduction characteristics of four systems: BaO/Al 2 O 3 alone, a sequential system with Pt/SiO 2 ahead of the BaO/Al 2 O 3 , a combined system with the Pt/SiO 2 and BaO/Al 2 O 3 physically mixed, and BaO/Al

The hypothesis that ammonia concentrations can be amplified by reaction with NO in excess CO to form isocyanic acid (HNCO) which is then hydrolysed back to NH3 has been tested. With 1000 ppm NO and 400 ppm NH3 in 3400 ppm CO, the HNCO produced in a d

The reaction between NH3 and NO in excess CO over silica-supported platinum, palladium, and rhodium has been investigated for temperatures from 100 to 450 °C. As found previously for the corresponding reactions of H2/NO/CO mixtures, isocyanic acid (
