Automated laboratory testing unit for isobutane dehydrogenation catalyst (idc) in a pseudo-liquefied layer

Application

Laboratory unit is designed to determine the activity and selectivity of isobutene dehydrogenation catalyst (KDI; KDI-M) in a fluidized bed. Continuous automatic operation mode allows to carry out tests of KDI and KDI-M resource and to explore the physico-chemical properties of pulverized catalysts as well as the technological parameters of the fluidized bed.
