The present study is dedicated to the coupled CFD-kinetics 2D axisymmetric modeling of plasma-assisted diesel fuel reformer developed for two different applications: (i) onboard H2 production for fuel cell feeding and (ii) NOx trap regeneration. These cases correspond to very different reacting conditions. In the first case, diesel fuel reacts with air while in the second case it reacts with di...

The mono-metallic and bi-metallic catalysts have been prepared by impregnating with solutions containing a compound of H2PtCl6,WO3 and 1ml HCl (0.1 mol). It should be noted that the catalysts’ activity and selectivity have been determined under these conditions : 450-5000C ,and 15-25atm by H2. For converting n-heptane , the molar ratio H2/C7H16 is 5 , and LHSV is 1.5ml/h. It has been proved tha...

the series of mono-metallic and bi-metallic catalysts have been prepared by impregnatingwith solutions containing compound of h2ptc15,nbc15 and lml hc1 (0.1 mol). the activityand selectivity of the catalysts have been determined under conditions at 450-500°c, 15-30atm. molar ratio h2/c7h16=5 and vvh=1.5/h for converting n-heptane. under theseexperimental conditions it has been established that ...

In insulin-producing cells of the RINm5F line, the nonmetabolized analogue of L-leucine, 2-aminobicyclo[2,2,1]heptane-2-carboxylic acid decreases O2 consumption, lowers ATP content, and inhibits insulin release despite stimulation of both NH4 production and 14CO2 output from cells prelabeled with L-[U-14C]glutamine. The metabolic and secretory effects of 2-aminobicyclo[2,2,1]heptane-2-carboxyli...

Mesoporous silica SBA-15 in the form of 10-30 μm sized sheets with unusually large ordered pores has been synthesized using heptane as a cosolvent in the presence of NH4F. The resulting morphology of 400 nm thick sheets that contain easily accessed, hexagonally arranged, 18 nm sized pores running parallel to sheet normal has not been previously reported. The material has a BET surface area of 5...
