H2 generation by a modified Fe-steam process is carried out by reacting scrap Fe with steam to H2 and Fe304 in a shaft furnace of the usual type and recycling the Fe304 to iron and steel mfr.. Pref. the Fe304 is oxidised with 02 to Fe203 in another process stage and the heat ...
In this work, the use of ethanol as a reducing agent in the steam iron process will be investigated. Ethanol, at high temperature, decomposes mainly in syngas but can also form coke, which can compromise the process effectiveness, reacting with water and producing CO together with H...
A chromium-free catalyst for reacting carbon monoxide with steam to give hydrogen and carbon dioxide contains as active combination of substances: (a) 30 to 98 % by weight iron oxide represented by Fe2O3; (b) 0.1 to 20 % by weight copper... SCHNEIDER MICHAELDE,KOCHLOEFL KARLDE,MALETZ ...
6.5.1 Reactions with Gases Before moving on to describe the formation of porosity from gases in solution or reacting with its environment, it is worth emphasising that most porosity I have seen in most castings, including cast irons, is mostly air bubbles entrained by the poor design of fillin...
This is closely related to the specific volume of hydrogen reacting with the pellet’s internal surface. In cases of low porosity and small surface pore dimensions, gas encounters numerous obstacles in penetrating the pellet. Consequently, solid-state diffusion from the surface becomes more ...
New artificial intelligence capable of reacting to hundreds of different situations Scenarios: Grand campaign scenarios (where it is possible to choose any of the nations involved): 1914 The Great War (starting on June 27, 1914) 1933 Day of Decision (starting on March 4, 1933) ...
This includes not only properly directing the units, but also reacting skillfully to the dynamically changing, destructible environment. All the characters, as well as the machines have been carefully designed, reflecting well the unique climate of the interwar times. Try out various game modes ...

To evaluate these effects, the RI values for the different reacting gases and the crushing strength of the particles were plotted as a function of ΔXs in Fig. 5. Reactivity with O2 barely varied regardless ΔXs. But the reactivity with H2 or CO increased when it was highly reduced, i.e...
Effective performance of these processes depends on sound process design and engineering to ensure that good contact is obtained between reacting gases and solids. Ultimately, their performance depends on how closely they can approach the theoretical energy requirements for the reaction system at throughpu...
