DOI: 10.1016/j.ces.2020.116345
Abstract: Abstract Gas-solid micro fluidized beds have unique characteristics such as bed pressure drop overshoot, delayed minimum and bubbling / slugging but advanced turbulent fluidization, as well as negligible gas back-mixing. The data covering a wide… read more here.

DOI: 10.3390/min7110209
Abstract: The mechanism and kinetics of the reduction of hematite to magnetite in a laboratory-scale, micro-fluidized bed reactor were isothermally investigated. The procedure consisted of the isothermal heating in a flow of a 20%CO–80%CO2 mixture at… read more here.
