Effect of water addition and stoichiometry variations on temperature profiles in an autothermal methane reforming reactor with Ni catalyst

Fuel cell feed system based on H2 production by a compact multi-fuel catalytic ATR reactor

“…It is a thermal self-sustained catalytic process, in which the exothermicity of hydrocarbon oxidation reactions supplies to the system the heat needed for the SR reaction; therefore along the catalytic bed the temperature quickly raises the first zone, and then slowly decreases until the end [4,5]. The thermal balance of the ATR reaction as well as the hydrogen yield depend strictly on the feed ratio values x and y [6]. Auto-thermal operation point is the condition at which the energy requirements of the SR reaction are balanced by oxidation reactions [7].…”

Monolith and foam catalysts performances in ATR of liquid and gaseous fuels

“…Finally, the activity of catalytic foam was analysed, by using the JM catalyst for a total catalytic volume of 50 cm 3 In the Fig. 16 the thermal profile along the catalyst is reported.…”

“…It is a self-sustained catalytic process, in which the exothermicity of hydrocarbon oxidation reaction supplies to the system the heat needed for the SR reaction; therefore, as a typical ATR reactor behavior, along the catalytic bed the temperature quickly raises the first zone, and then slowly decreases until the end [2]. Exothermicity of the reaction as well as hydrogen yield depend strictly on feed ratio values x and y [3]. Auto-thermal operation point is the condition at which the energy requirements of the SR reaction are balanced by oxidation reactions [4].…”

Structured Perovskite-Based Oxides: Use in the Combined Methane Reforming

“…At 650˚C, after a 12 h induction period, a 67% methane conversion was obtained. At the beginning of the reaction, oxidation of metallic nickel could occur due to the high affinity between Ni and O 2 [23]; which is then progressively reduced by the H 2 produced in the reforming reaction, until stability is reached. 100% oxygen conversion was obtained during the entire tests, due to the fact that oxidation reactions are thermodynamically and kinetically favored [24].…”
