“…This can be related to a lower open porosity of particles III and larger amount of macro pores. Previously, 100%-Co showed good performance in deep oxidation of hydrogen in hydrogen-air mixtures [4]. Figure 3 demonstrates its performance in deep oxidation of СО and propane.…”

“…Most suitable for the purpose seem to be the oxide and complex-oxide systems both in the form of catalyst [1] or as a support for active phase [2], including those prepared by solutioncombustion synthesis [3]. Good catalytic performance and stability have been shown by Ni-Co-based polymetallic catalysts derived from SHS-produced complex intermetallics [4] and supported polymetallic catalysts prepared by self-propagating surface synthesis [5].…”

“…The ingot of synthesized xCoAl 3 ⋅yVAl 3 intermetallic was broken to pieces and crushed to obtain a powder with a particle size of 100-300 μm. The powder was then leached with NaOH solution, washed, and stabilized with Н 2 О 2 solution to get catalysts II and III (see Table 1) as described in detail elsewhere [4,12].…”

“…Catalytic activity of synthesized catalysts was measured using the silica flow reactor with a fixed bed of catalyst (1 cm 3 ) described in [4,12]. In the process of deep oxidation, we used the following gaseous mixture (vol %): 0.2% propane, 0.6% СО, 2% О 2 , and N 2 the rest.…”

Polymetallic Co90-V10 catalyst was derived from an SHS-produced Co-V-Al precursor and its performance in the deep oxidation of СО, propane and in the СО 2 hydrogenation was determined and compared with that of previously synthesized Co100 and Co95-V5 polymetallic catalysts. The precursor and catalyst were characterized by XRD, SEM, and BET analyses. In the processes of deep oxidation, Co90-V10 catalyst showed the best results. The CO 2 hydrogenation turned independent of V content of catalyst. A maximum of CO 2 conversion (65% at 350°C) was exhibited by Со100 catalyst. The СО 2 conversion over Co100 and Co95-V5 catalysts was found to show a maximum at a gas hour space velocity (GHSV) of 6000 h -1 .
