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...

Parametric Study of Hydrogen Production from Ethanol Steam Reforming in a Membrane Microreactor

Microreactors are miniaturized chemical reaction systems, which contain reaction channels with characteristic dimensions in the range of 10-500 μm. One possible application for microreactors is the conversion of ethanol to hydrogen used in fuel cells to generate electricity. In this paper a rigorous isothermal, steady-state two-dimensional model was developed to simulate the behavior of a membr...

Sustainable Hydrogen Production by Catalytic Bio-Ethanol Steam Reforming

Cost Analysis of Plasma Catalytic Reforming of Hydrocarbons

Thermal plasma reforming offers advantages in hydrocarbon reforming especially in small to medium scale plants and in plants with fast transients. The combination of a thermal plasma reformer operating with partial oxidation with a catalyst bed will be described. Reduced concentrations of CO (1-3% vol) can be achieved, with high hydrogen yields and minimal plasmatron electrical power requiremen...
