The Ca(OH)₂/CaO loop offers a promising solution for seasonal thermochemical heat storage, vital decarbonizing the heating sector thanks to its high energy density and abundant raw materials. However, cyclic hydration/dehydration of limestone-derived CaO (r-CaO) faces challenges like agglomeration high-volume expansion, limiting expected performances. This study focuses on fabricating hollow microspheres (h-CaO) with porous shells via facile one-pot hydrothermal synthesis method, without...
To promote the formation of CO2 hydrate for cold energy storage, influence gas-inducing agitation at varying operating speeds were studied experimentally. A comparison was made with normal stirring (without gas inducing) from perspectives deviation equilibrium condition, subcooling, agglomeration, and production. The test results revealed that contributed to a closer shift profiles towards conditions when compared stirring. However, this advantage became less pronounced as speed increased....
A process to coat particles of active pharmaceutical ingredient (API) onto microcrystalline cellulose (MCC) excipient shows promise as a new way dosage forms showing enhanced drug release. The consists fluidized bed operated at elevated pressure in which API are precipitated from Supercritical Anti-Solvent (SAS). MCC were used an the and collect SAS-generated particles. Naringin was selected model MCC. number operational parameters investigated: fluidization velocity, coating pressure,...
Production of active ingredients such as pharmaceuticals in nano-particulate form is highly desirable but the resulting product difficult to handle and use applications. A novel process described for coating nanoparticles onto excipient particles c. 300 μm by rapid expansion a supercritical solution (RESS) into two types modified proprietary equipment: Wurster coater fluidized bed. This approach has been demonstrated through successful deposition six mimics (benzoic acid, adamantane,...
The solubility of borage, echium, and lunaria oils in compressed CO2 was measured using the dynamic method. Pressure temperature were varied from (60 to 300) bar (10 55) °C, respectively. solubilities compared those other vegetable correlated density-based model proposed by Chrastil. As predicted model, a linear relationship between logarithm solvent density obtained. Average deviation calculated did not exceed 14%.
This experimental study aims to investigate the characteristics of supercritical nitrogen (N2) internal flow convective heat transfer. A series transfer experiments were conducted with N2 flowing upwardly in a uniformly heated vertical circular bare stainless steel tube (4.57 mm ID) under pressures 3.5 and 4 MPa that beyond its critical pressure (3.4 MPa), mass fluxes 27.9, 38.1, 50.8 kg/m2-s, 8.1, 9.3, 11.2 kW/m2, respectively. Experimental results demonstrate behaves similarly as other...
The effect of different matrix pretreatment winter savory(Satureja montana L.) on the supercritical CO2(SC-CO2) extraction - yield, composition and antimicrobial activity extracts essential oil (EO) was investigated. Herb submitted to conventional mechanical grinding, physical disruption by fast decompression subcritical CO2 compression. analyses obtained SC-CO2 hydrodistillation were done GC/FID method. Major compounds in savory EO were: thymol (30.4-35.4% 35.3%), carvacrol (11.5-14.1%...
Superhydrophobic surfaces are of paramount importance for a great number applications ranging from heat transfer to medicine. However, their mass production is challenging environmental and scaling points views. This work proposes simple, scalable, method superhydrophobic porous materials. In particular, highly hydrophobic CH2/CH3-grafted copper achieved via exposure high-pressure supercritical CO2 + H2O environment. The hydrophobicity was further reinforced by using hierarchical...
