Coffee roasting : exploring the impact of the time-temperature profile on the formation kinetics of volatile organic compounds by PTR-MS

open access: yes, 2009
Green coffee was roasted in a laboratory scale fluidized bed roaster to a fixed end point (dark roast) using different roasting temperatures (isothermal roasting) - 228°C, 238°C, 248°C and 258°C.

Efficient flotation of smithsonite using sulfidation reconstruction based on fluidization roasting

open access: yes
There is an urgent and unprecedented demand for the selective separation of zinc oxide minerals from refractory zinc oxide ores due to declining reserves of zinc sulfide ores. Smithsonite, as a typical zinc oxide resource, requires sulfidation to enhance
