In the present study, we carried out the hydrogenation of carbon dioxide in a transparent column to observe the bed behavior. We used relatively large particles as fluidized catalysts. The emulsion phase of the fluidized bed with these particles does not expand when we found that the fluidization quality decreased with increasing reaction rate and finally the defluidization occurred even when the relatively large particles were used as the catalysts. We studied the effects of the reduction rate of gas volume on the fluidization behavior. The criterion for the stable operation could be successfully given by the reduction rate of gas volume due to reactions. This criterion is useful to determine the operating conditions to establish good fluidization}, pages = {87--91}, title = {流動触媒層の流動性に及ぼすエマルション相ガスの体積減少速度の影響}, volume = {47}, year = {2005} }
