Preparation and Characterization of Inorganic PCM Microcapsules by Fluidized Bed Method

Preparation and Characterization of Inorganic PCM Microcapsules by Fluidized Bed Method

The literature shows that inorganic phase change materials (PCM) have been very seldom microencapsulated, so this study aims to contribute to filling this research gap. Bischofite, a by-product from the non-metallic industry identified as having good potential to be used as inorganic PCM, was microencapsulated by means of a fluidized bed method with acrylic as polymer and chloroform as solvent,...

The preparation of the sustained release metformin hydrochloride microcapsules by the Wurster fluidized bed.

The main objective of this study was to prepare sustained release metformin hydrochloride microcapsules by the Wurster fluidized bed and to obtain the optimized coating process and formulation. Fine microcapsules without agglomeration were obtained in a continuous coating process with the atomization air pressure of 0.2Mpa and an appropriate coating speed temperature. With other design variable...

Fluidized Bed Disposal of Secondary Sludge High in Inorganic Salts

The authors have presented an excellent example of the total systems approach to overcoming a dif­ ficult waste disposal problem. They have presented useful guideline data for fluid bed incinerators which are increasingly being adopted for thermal destruc­ tion of difficult organic sludges. Although not of concern in the design described, the fluid bed incinerator has the special capability of ...

Preparation and Characterization of Novel Microcapsules

Numerical study of heat transfer in fluidized bed dryers by volume of fluid ‎method

The purpose of this study is numerical modeling of temperature variation of phases in a two phase regime in fluidized bed dryers including particles belonging to Group D of geldart classification. The mass transfer between phases is not taken into consideration in this modeling which has been assumed in three- dimensional, unsteady, and two-phase regime.To verify the modeling we consider the do...
