Near-Infrared Analysis and Process Control of Pharmaceutical Pelletization Processes
This study explored the potential of near-infrared spectroscopy in the determination of pharmaceutical pellet characteristics and to predict desired process endpoints during fluidized bed drug suspension layering and coating operations. Various strengths of diltiazem HCl pellets were prepared via a …

Torrefaction and Steam Explosion of Selected Biomass for Biofuel Production
… as additives at different proportions during pelletization. The addition of binders (torrefaction liquid and sawdust) to the pellet formulation increased the tensile strength of the torrefied WSS by approximately 50%. The OH groups in the biomass break down to a limited degree due to …

Investigations into the recycling of quarry wastes from the South East of England
… However, carbonating the mixes during pelletization was found to have a beneficial effect on final pellet strength. After further hydration in air for 6 weeks, the pH of these pellets was reduced considerably, when they were further carbonated for 24 hours in the CO2 chamber. …

Compaction behavior, mechanical properties, and moisture resistance of torrefied and non-torrefied biomass pellets
… that torrefied biomass required 50% ~ 200% more pelletization energy than non-torrefied biomass. Additionally, in general, the hardness of torrefied biomass pellets was lower than non-torrefied pellets. However, it was found that the moisture resistance of the torrefied biomass pellets was higher …

Upgrading biomass by hydrothermal and chemical conditioning
There are two widely known thermal pretreatment technologies, known as hydrothermal carbonization and dry torrefaction. In dry torrefaction, also known as torrefaction or mild pyrolysis, dry solid biomass is treated in an inert gas environment in a temperature range of 200-300oC for more than one …

Solubility enhancement, mechanical properties and taste masking of poorly water soluble compounds by optimizing hot melt extrusion processing
Pharmaceutical research includes investigation and development of a new drug and determination of the delivery route and delivery system, as well as the technology to create the delivery system. It can also consist of a combination of these steps. Researchers studying potential delivery routes have …
