One-step hydrocarbons steam reforming and CO2 capture

چکیده
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 towards H 2 and CO 2 and all of the parallel reforming/gasification reactions are also influenced in favour of the desired products. Accordingly, a hydrogen-rich product gas results with reduced CO and CO 2 concentration.

Hydrogen Production via Steam Reforming with CO2 Capture
Hydrogen demand in refineries is increasing vigorously due to the stringent transportation fuel specifications, furthermore the interest in the so-called hydrogen economy developed in the recent years put the hydrogen as energy carrier in the centre of a growing interest. More than 95% of the hydrogen for refinery use is nowadays produced via hydrocarbon steam reforming, where Foster Wheeler pl...
متن کاملLarge-scale Hydrogen Production
There is a growing need for hydrogen and a future hydrogen economy is high on the political agenda. But where should the hydrogen come from? The “sustainable” routes are still too expensive. Steam reforming of hydrocarbons is the most feasible route today. If CO2-sequestration is accepted, fossil fuels may play an important role in a starting future “hydrogen economy”. This will happen by use o...
متن کاملTwo novel oxy-fuel power cycles integrated with natural gas reforming and CO2 capture
Two novel system configurations were proposed for oxy-fuel natural gas turbine systems with integrated steam reforming and CO2 capture and separation. The steam reforming heat is obtained from the available turbine exhaust heat, and the produced syngas is used as fuel with oxygen as the oxidizer. Internal combustion is used, which allows a very high heat input temperature. Moreover, the turbine...
متن کاملHydrogen-Rich Gas Production by Sorption Enhanced Steam Reforming of Woodgas Containing TAR over a Commercial Ni Catalyst and Calcined Dolomite as CO2 Sorbent
The aim of this work was the evaluation of the catalytic steam reforming of a gaseous fuel obtained by steam biomass gasification to convert topping atmosphere residue (TAR) and CH4 and to produce pure H2 by means of a CO2 sorbent. This experimental work deals with the demonstration of the practical feasibility of such concepts, using a real woodgas obtained from fluidized bed steam gasificatio...

An experimental and kinetic modeling study on the Ni-catalyzed conversion of methane under oxidative and reforming conditions is presented. The numerical model is based on a surface reaction mechanism consisting of 52 elementary-step like reactions with 14 surface and six gas-phase species. Reactions for the conversion of methane with oxygen, steam, and CO2 as well as methanation, water-gas shi...
