Modeling of Laboratory Steam Methane Reforming and CO2 Methanation Reactors

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...

Production of hydrogen by unmixed steam reforming of methane

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...

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...

One-step hydrocarbons steam reforming and CO2 capture

1. Introduction Already in 1868 [1], H 2 was produced by the steam reforming (eq.1) of hydrocarbons in the presence of a calcium oxide, and the use of natural calcium-based sorbents as candidates to remove CO 2 in situ from reactors has been receiving increasing attention. Through simultaneous CO 2 absorption (eq.3) the equilibrium of the homogenous water gas shift reaction (eq.2) is shifted to...
