Pyrolysis of biomass to produce H-rich gas facilitated by simultaneously occurring magnesite decomposition

Carbon Resources Conversion
This study investigated how biomass pyrolysis varies with the different fractions of magnesite mixing into biomass. The pyrolysis occurred with simultaneous decomposition of magnesite without use of any gasification reagent, and was analyzed in terms of ...

Measurement of the pure dissolution rate constant of a mineral in water

, 2008
We present here a methodology, using holographic interferometry, enabling to measure the pure surface reaction rate constant of the dissolution of a mineral in water, unambiguously free from the influence of mass transport.

Note on magnesite formation (Studies on irreversible geochemical reactions N° 9)

Carnets de Géologie, 2003
In recent laboratory experiments magnesite (MgC03) has been synthesized at a temperature of 313°K (= 40°C). The experiments have demonstrated that irreversible reactions are involved in the low-temperature formation of magnesite.

Negative activation volume for dielectric relaxation in hydrated rocks

, 2010
Negative defect activation volumes are extremely rare in solids. Here, we report for the first time that this holds in a couple of hydrated rocks for dielectric relaxation by exploring the complex impedance spectra at various pressures and temperatures ...

Determination of the PZC of magnesite and talc by the ELS technique [PDF]

Acta Montanistica Slovaca, 1998
The paper presents the results of zeta potential measurements of magnesite and talc by the laser - Doppler electrophoretic light scattering ( ELS ) technique. The PZC of magnesite is located at pH 7,2 , while that of talc at pH 2,7.

Small is the New Large: Demonstration of how Microanalyses Elucidate Large‐Scale CO2 Uptake Through Mineralization

Advanced Sustainable Systems, Volume 10, Issue 2, February 2026.
Imaging techniques like X‐ray microcomputed tomography and electron microscopy are integrated to understand the CO2 mineralization process at the pore‐scale. These techniques are used to characterise the reaction progression in basalt. They increase the reliability of reactive transport modeling and consequently improve the CO2 storage capacity ...
