Biomass chemical looping gasification (BCLG) is a complex process for the conversion of biomass using an oxygen carrier, which influenced by various operating parameters. For better understanding this process, steam ilmenite as carrier numerically investigated in work multiphase particle-in-cell (MP-PIC) method, modified Euler–Lagrange approach. As first step, reduced reaction network spouted b...

In the present work, the drying of calcium carbonate in a batch spouted bed dryer with inert particles has been investigated experimentally. The effect of several operating parameters including air temperature (90, 100, and 110 ˚C), air velocity (Ums, 1.2 Ums, and 1.5 Ums), and dry solid mass (5, 10, 20 g) has been studied. The Taguchi method has been applied to determine the optimal parameters...

The CFD-DEM methodology is a popular tool for the study of fluid–particle systems, and there are several programs that permit using it. In this study, we employed it to simulate pseudo-2D spouted bed, comparing performance Ansys Fluent MFiX. results analysed commented on in terms both accuracy computational efforts. Despite similarity setup, MFiX seems perform significantly better. similarities...

Coffee roasting is a heat treatment process that transforms green coffee into product can subsequently be ground and brewed. Understanding critical in developing new downstream processes formulations, as well optimising existing ones. Positron Emission Particle Tracking (PEPT) allows tracking of particles equipment has been used here to characterise particle dynamics beans within spouted bed ro...
