Fluidisation of Thermochemical Energy Storage Materials: Degradation Assessment

Composite zeolites impregnated with anhydrous salt particles are promising materials for use in domestic thermochemical energy storage (TCES), however they have limited power output. Fluidization has the potential to increase mass and heat transfer of TCES systems. In this study, a composite material LiX zeolite MgCl2 is produced. This batch then fluidized at different gas velocities study whether degradation these occurs when fluidizing. Images after fluidizing analyzed using validated method utilizing microscope images specialized software used fragmentation or abrasion been induced by fluidization. were found increased average diameter 7%−8%, which could be due imperfect dehydration impregnation process, but also observed conglomerates present on surface some particles. Overall, excess was not fluidization any velocity. No loss measured sample fluidization, no appreciable observed. The 0.6192 mm 0.6799 prior 0.6405 0.7088 However, change statistically significant, it shown that unlikely. Despite this, fines produced an 3.60 μm (σ = 1, ±2.34 μm), as such hazard if inhaled.
