Abstract:
<p>Vehicles powered by fuel cells are from an environmentalaspect superior to the traditional automobile using internalcombustion of gasoline. Power systems which are based upon fuelcell technology require hydrogen for operation. The ideal fuelcell vehicle would operate on pure hydrogen stored on-board.However, storing hydrogen on-board the vehicle is currently notfeasible for technical reasons. The hydrogen can be generatedon-board using a liquid hydrogen carrier such as methanol andgasoline.

Abstract:
Proton exchange membrane fuel cell (PEMFC) has been reported as clean and efficient energy technology from conversion of H₂. However, one of the main challenges remains the storage and transport of hydrogen. The promising alternative is to produce H₂ on site by a reformer using a H₂-dense liquid as a fuel, a technology known as fuel processing. Methanol is an attractive source of H₂ compared to other fuels as it presents several advantages, i.e. it is obtained sulphur-free, has a high H to C ratio and therefore produces a H₂-rich reformate, can be reformed at low temperatures (200 - 300°C) and

Abstract:
博士<br>臺灣大學<br>化學工程學研究所<br>96<br>The methanol steam reforming on double-jacketed palladium membrane reactors was studied by numerical simulation. A catalytic oxidation of methanol and/or hydrogen was used to provide the necessary heat for steam reforming, and hydrogen permeation by palladium membrane takes place simultaneously. The molar fractions of species and reformer temperatures were analyzed under co-current and counter-current operation between oxidation and reformer sides. The results indicated that the co-current operation outperforms the counter-current operation because of higher met

In this study, we found that it could also speed up the forward reaction rate and turnover frequency when a palladium membrane was used in the catalytic reactor. This experiment used G-66B as the basic catalyst and a 1%Pd/CuOZnO catalyst to study reaction rate of steam reforming of methanol with the WHS

A tubular packed-bed reactor performing the methanol steam reforming (MSR) process was modeled by adopting computational fluid dynamics (CFD) software to analyze its performance. The methanol steam reforming, reverse and forward water gas shift reactions were considered in this model. The kinetic parameters of the reactions were fitted according to our previous experimental results. Accordingly, the performance indices of the r

Abstract:
Steam reforming of methanol and hydrocarbon are currently the processes of choice to produce hydrogen. Due to the endothermic nature of these reactions, zones of low temperature are commonly found in reformers. These zones can potentially damage the reformer through thermal stresses. Moreover, the response time and size of a reformer are controlled by the heat available to the reaction. The objective of this thesis is to demonstrate the feasibility of using fiber Bragg gratings as an alternative solution for temperature monitoring in methanol and methane steam reformers. To meet this objective

Gallium regarded as active metal center and manganese oxide as available functional support to provide oxygen atoms. Based on electron interaction between the bimetallic interfaces, oxygen vacancies are induced and then release oxygen atoms. These steps can improve the methanol conversion to increase catalytic activity in the steam reforming of methanol reaction. In the preparation of catalysts, adjusting the pH
