Impact of Metal Ridging on the Fluidization Characteristics of FCC Catalyst. (2002)

Whitcombe, Joshua Matthew, Agranovski, Igor E, Braddock, Roger David

Minimum fluidization and bubbling velocities were used to compare the fluidity of FCC catalyst sourced from various refineries. It was found that fluidity characteristics of the catalyst of the same...

Coupling between cycles of phytoplankton biomass and aerosol optical depth as derived from SeaWiFS time series in the Subantarctic Southern Ocean. (2002)

Gabric, Albert Jerome, Cropp, Roger Allan, Ayers, Gregory P., McTainsh, Grant Harvey, Braddock, Roger David

The Subantarctic Southern Ocean is a high-nutrient low-chlorophyll region, and it has been suggested that primary production is limited by deep mixing and the availability of iron. Australian dust is...
