Characteristics of Carbon Dioxide Hydrogenation in a Fluidized Bed Reactor
Characteristics of CO2 hydrogenation were investigated in a fluidized bed reactor (0.052 m ID×1.5 m in height). Coprecipitated Fe-Cu-K-Al catalyst (d(p)=75-90 μm) was used as a fluidized solid phase. It was found that the CO2 conversion decreases but the CO selectivity increases, whereas the space-time-yield attains maximum values with increasing gas velocity. The CO2 conversion has increased, but CO selectivity has decreased with increasing hydrogenation temperature, pressure or H2/CO2 ratio in the fluidized bed reactor. Also, the CO2 conversion and olefin selectivity appeared to be higher in the fluidized bed reactor than those of the fixed bed reactor.
