By using combinations of a ceria/zirconia-supported metal catalyst with the alumina support it is shown that the formation of ethene does not inhibit the steam reforming reaction at higher temperatures. It is concluded that the support plays a significant role in the steam reforming of ethanol....
Especially, when electrically heating the plate-type Pt-doped Ni catalyst to 700 °C, the SRM reaction system could reach a stable state within ca. 10 min, which offered a strong possibility to shorten the startup time from the 1–2 h of conventional reformer to just few minutes. In ...

An object of the present invention is to solve the foregoing problems experienced with the material for reforming reaction tubes for the generation of hydrogen and to provide a heat-resistant cast steel which has heat resistance and high-temperature creep rupture strength required of steam reforming ...
Special configurations of the feedwater distributors (8- 11) are proposed, which enhance the safety of the steam generator in the case of malfunctions, for example, absorb the reaction forces of torn tube lines. Furthermore embodiments of the steam- collectors (27) are proposed which facilitate...
In this work, the effect of the metal nature on the reaction mechanism of the partial oxidation of ethanol on Pt/CeO2 and Rh/CeO2 catalysts was studied by using diffuse reflectance infrared spectroscopy (DRIFTS) analyses. The results showed that the nature of the metal affected the reaction ...
As a raw material and water vapor hydrocarbons is placed industrial furnace 100 of firing the fired combustion heat generated by burning a fuel, flows into and fills the reforming catalyst for accelerating the steam reforming reaction in... 蔵島 吉彦,本多 俊彦 被引量: 0发表: 2005年 ...
However, N2 physisorption measurements revealed that the porous structure of silica shell collapsed during reduction and reforming, which was attributed to the instability of silica shell under the high reaction temperature, especially in the presence of produced steam at high temperatures. This has ...
Side effects in the treatment of lead poisoning include a febrile reaction with headache, myalgia, nausea, and vomiting. Furthermore, EDTA may redistribute lead to the brain after acute or chronic lead exposure (Andersen, 2004). Lacrimation, nasal congestion, mucocutaneous lesions, glycosuria, ...
