Hydrogen Production Using Ethanol-Steam-Reforming Reactor with Cu/ZnO/Al2O3 and Ru/Al2O3 Catalysts

C214 AN ANALYTICAL AND EXPERIMENTAL STUDY OF ETHANOL STEAM REFORMING WITH Cu/ZnO/Al_2O_3 CATALYST(Hydrogen and Reforming-1)

“…Previous studies on the etlianol refbrming are chemieal approaches on catalysts or calculations under ideal conditions, with experiments using compact-size reactors whose diameter is of 4m10mm, (see references [1][2][3][4][5][6]). On the other hand, expect for our recent study [7].…”

“…Recently, we have conducted a fundamental approach for the optimum design of the ethanol steam-reforrning reactog including the choice of catalysts [7]. Our final aim is to establish the criteria for practical reactor designs.…”

“…We have used two types of the most common catalysts; namely, Cu!ZnOfA1203 As well as reference [7],'the present study is a fundamental approach for the optimuni design of the ethanol steam-refbrrning reactog using a based-metal We need a pre-process to deoxidize the catalyst, using nitrogen N2 gas (1) and hydrogen H2 gas…”

“…The reactor is heated at the vaporizer using a 600W heater and at the reaction cylinder using a 1200W heater. Tlemperature are measured by sheathed thermocouples (7) of type K. We monitor the coking on the catalyst by the pressure difference between the upstream and downstream ends ofa catalyst-layer bed, using pressure gages (8), The gas from…”

“…(3) H20AitOH, (4) pump, (5) yaporizer, (6) Teactor (reaetion cylinder), (7) thermocouples, (8) pressure gages, (9) terminal block, (10) PC (11) condenser, (12) gas chromategraphM H2 gas analyzer and fiow meter, the reaction cylinder passes a condenser (11), where condensed or aqueous constituent parts sueh as water and etlianol are absorbed, Next, the gas passes a silica-gel dryer, and is measured its hydrogen and other constituents concentrations using a gas ehromatography and a H2-gas analyzer (12). The H2-gas analyzer is only used to monitor and to eheck date.…”
