The CO concentration of the gas leaving the reformer must be reduced up to a specified level, with two main goals: (1) to increase the H 2 production rate and (2) to purify the process stream. To these ends, the water鈥揼as shift reaction (WGSR) is widely used. An attractive ...

The methane/steam reforming process can be reduced to two dominant reactions: the methane/steam reforming reaction, Eq. 1, and the water-gas shift reaction, Eq. 2. $$ \mathrm{CH_{4}}+\mathrm{H_{2}O} \rightarrow 3\mathrm{H_{2}}+\text{CO}, $$ (1) $$ \text{CO}+\mathrm...

We hypothesized that acclimation in the CWD area will result in an upward shift of the thermal tolerance limits of clams, and this shift will be associated with upregula- tion of stress protection mechanisms at high temperatures. To test these hypotheses, we determined the expres- sion of ...
of two phase model was worked out.The results showed that the most complicated part is at the bottom of the riser reactor.The flow field,turbulent energy and catalyst concentration field of both gas and solid phases are characteristic of big gradients in the radial,axial and tangential ...
During the discharging process, sorbent and sorbate react producing an exothermic reaction that releases heat. The main advantages of sorption heat storage are higher energy density and negligible heat losses compared to a conventional thermal storage based on sensible heat. A conventional water storage...
Production pressure is higher for a two-phase system of air-water with respect to that of a single-phase system. Also, as the quantity of the injected gas increases, production pressure increases. • Increasing the mass flow rate increases the production temperature. There is an optimum mass...
understanding the role of heat is critical since the rates of chemical reactions usually present an exponential dependence on the temperature, as dictated by Arrhenius law13. Therefore, small temperature variations could lead to significant changes in the reaction rates. For this reason, significant ef...
