Experimental studies and comprehensive reactor modeling of hydrogen production by the catalytic reforming of crude ethanol in a packed bed tubular reactor over a Ni/Al22O33 catalyst

Simulation and control of water-gas shift packed bed reactor with inter-stage cooling

“…This model consists of mass and energy balance equations with the incorporation of intra-particle mass and heat transfers. The assumptions that govern these equations are: (1) only the axial temperature change is taken into account, (2) the radial temperature change is neglected due to the fact that the diameter of the reactor is small and adiabatic (no heat loss from the surface of the reactor); see [15], (3) momentum conservation equation has been disregarded in this model because the bed height is too small to create a significance amount of pressure drop, i.e., see [16], (4) is neglected. Equations (5) - (7) show the mass and energy balance equations for the PBTR system.…”

“…The transfer function is obtained through linearizing the control variable against the manipulated variable which in this case is the flowrate of the inter-stage coolant. Equation (15) shows the transfer function obtained from linearizing the abovementioned variables. Conventional feedbackfeedforward control structure.…”

A Catalyst Supporter to Lower the Carbon Monoxide Content in Ethanol Reforming

“…К настоящему времени выполнено множество ра-бот по изучению процесса конверсии этанола в газо-вую смесь, богатую водородом [1][2][3][4][5][6][7][8][9][10][11]. Как правило, в смеси, кроме водорода, наблюдается присутствие метана, моноокиси и двуокиси углерода, а также не-прореагировавший этанол, вода и ацетальдегид.…”

Effect of WO_x Over Ni/Hydrotalcite Catalysts to Produce Hydrogen from Ethanol

“…CH 3 CHO and the CH 2 =CH 2 are intermediary products that could be formed during reaction at relatively low temperatures before the formation of H 2 and CO 2 and it is also possible to form coke over the surface of the catalyst.…”

“…The catalytic ethanol steam reforming has been reported to produce hydrogen and low amounts of CO and CO 2 [3][4]. Another attractive point of this reaction is related with the energy required to produce H 2 .…”
