The random pore model (RPM) is the most comprehensive model for non-catalytic gas-solid
reactions. The application of RPM is critical in some environmental pollutant removal …

The hydrogen-based direct reduction of iron oxide (DRI) provides a sustainable approach to
cleaner ironmaking. In this research, for analyzing hydrogen-based DRI in pellet scale, the …

This work aims at investigating the kinetic mechanisms of the reduction/oxidation (redox)
reactions of iron oxide/iron pellets under different operating conditions. The reaction …

In gasification of biomass, coal and blended biomass and coal, there are two steps including
an initial pyrolysis process followed by gasification of solid char. The latter process is a slow …

With the aim of removing hydrogen sulfide (H 2 S) from a gaseous phase around room
temperature, we studied the performance of an iron oxyhydroxide (ferrihydrite) adsorbent by …

In the present work, mathematical modeling of SO 2 removal reaction with CuO was
performed by random pore model, modified grain model, and volume reaction model. In …

Natural gas deep desulfurization process by zinc oxide adsorbent is an example of
noncatalytic gas-solid reactions, which plays a crucial role in petrochemical and refinery …

The present work deals with a complete study on activated carbon production from physical
activation of pistachio shell. The effect of different parameters was investigated in the …

Increasing concern about sulfur dioxide (SO2) from diesel vehicle exhausts causing
detrimental effects on NOx removal catalysts has resulted in the development of dry …

The kinetics of the reaction between CaO and SO2 was studied by the random pore model,
to accurately consider the porous structure of the solid reactant. The inherent reaction rate …
