CO capture with calcined dolomite: the effect of sorbent ...

CO2 capture with calcined dolomite: the effect of sorbent particle size ... A biomass gasification process including CO 2 capture by calcined limestone has been recently tested [7], achieving a H ... features of sorbent behaviour in the CO 2 capture process,

CO2 capture with calcined dolomite: the effect of sorbent ...

Calcined dolomite contains both calcium and magnesium oxides of which only the calcium oxide participates in the CO 2 capture process; this is because magnesium carbonate decomposes at a much lower temperature than calcium carbonate.

CO-2 capture with calcined dolomite: The effect of sorbent ...

This investigation is set in the more comprehensive study of an innovative fluidized bed reformer configuration for producing hydrogen from either biomass/coal syngas or natural gas, in which ...

CO2 capture by means of dolomite in hydrogen production ...

Depleting of the syn gas carbon-containing compounds by means of CO 2 capture on calcined dolomite has been carried out. The dolomite behavior as CO 2 sorbent and its regeneration has been investigated by means of Linseis (TG-DTA) coupled with FT-IR spectrometer.

Post combustion CO2 sorbents from carbonate rocks: …

Portuguese carbonate rocks (marble, limestone and dolomite) wastes were used to produces CaO sorbents for post-combustion carbon capture. The raw materials were crushed, reduced to powder, and calcined at 850ºC. The marble and carbonate rock based sorbents were lime whereas dolomite based sorbent was a CaO-MgO mixed material.

In-situ XRD Studies of dolomite based CO2 sorbents

process for improved hydrogen production with simultaneous CO 2 capture since the reactions are driven towards H 2 as CO 2 is captured by the solid sorbent (typically CaO or calcined dolomite ...

Calcium looping sorbents for CO2 capture - ScienceDirect

CO 2 capture performance of tested sorbents: (a) CO 2 capture capacity during 30 cycles and (b) conversion profiles during the first three cycles. Conditions: carbonation in 50% CO 2 (N 2 balance) for 30 min, calcination in 100% N 2 for 10 min, isothermally at 800 °C [166] .

Dolomites as Promising Natural CaO-based Sorbents for …

calcined dolomite becomes a more efficient sorbent than calcined limestone for CO 2 capture by Ca-Looping. Therefore, natural dolomites could be used to produce promising cost-effective and eco-friendly improved CaO-based sorbents for industrial CO 2 capture applications. In this work, two dolomite

Hydrogen Sulfide Capture by Limestone and Dolomite at ...

The physical structure of a limestone or dolomite to be used in in-bed sulfur capture in fluidized bed gasifiers has a great impact on the efficiency of sulfur capture and sorbent use.
