Sintering and agglomeration of Fe2O3-MgAl2O4

2020-4-1  Sintering is a physical process due to crystallite growth, and agglomeration is the cohesion of neighboring particles. Two factors may be associated with this improvement: the higher specific surface areas of oxygen carriers with low ratio of Fe 2 O 3 and higher

Sintering and agglomeration of Fe2O3-MgAl2O4

Abstract Fe2O3-based chemical looping combustion can be combined with steam-iron reaction and dry reform of methane for high-value-added products if Fe2O3 is deeply reduced. However, the deactivation caused by sintering and agglomeration worsens, which is an essential issue to be solved. In this study, the stability of Fe2O3-MgAl2O4 oxygen carriers was investigated not only in a packed bed ...

What is Agglomeration? - Glossary of Powder Mixing ...

Sintering. Sintering, also known as frittage, is a thermal agglomeration process during which the atoms within the materials diffuse and form bridges across distinct particles, joining them together. Sintering involves heating products without melting them, and as such is particularly well-suited for materials with very high melting points.
