Kinetics Analysis of Steam Reforming of Methane on Sponge Iron

Experimental Studies of Intrinsic Kinetics and Diffusion during Methane Steam Reforming

The intrinsic kinetics and diffusion behaviour of methane steam reforming have been investigated in this work. Measurements of effective diffusivities of the gases present in methane steam reforming have been carried out by using the steady-state technique over wide ranges of temperature and pressure in a modified Wicke-Kallenbach (W-K) type diffusion apparatus. The effects of diffusion limitat...

Production of hydrogen by unmixed steam reforming of methane

CFD-simulation of membrane reactor for methane steam reforming

A membrane reactor is a reaction system that provides higher productivity and lower separation cost in chemical reaction processes. In this paper, packed bed catalytic membrane reactor with palladium membrane for methane steam reforming was analyzed both experimentally and numerically. The numerical model consists of a full set of partial differential equations derived from conservation of mass...

CFD modeling and control of a steam methane reforming reactor

This work initially focuses on developing a computational fluid dynamics (CFD) model of an industrialscale steam methane reforming reactor (reforming tube) used to produce hydrogen. Subsequently, we design and evaluate three different feedback control schemes to drive the area-weighted average hydrogen mole fraction measured at the reforming tube outlet ( x̄H outlet 2 ) to a desired set-point va...

Simulation of a Solid Oxide Fuel Cell with External Steam Methane Reforming and Bypass

Fuel flexibility is a significant advantage of solid oxide fuel cells (SOFCs) and can be attributed to their high operating temperature. The eligibility of a combined heat and power (CHP) system has been investigated as a new power generation methode, in this study. Natural gas fueled SOFC power systems via methane steam reforming (MSR) yield electrical conversion efficiencies exceeding 50% and...
