Abstract
An alternative measurement of gas cross flow coefficient between the bubble phase and emulsion phase, and the density of the solid particles in the bubble of a gas-solid, two dimensional fluidized bed are proposed, using the tracer technique and leak-current method.
In the range of uo/umf from 1.5 to 7.0, the gas cross flow coefficient （Kbd）b and density ratio γb are decreased rapidly and exponentially, respectively, with the increase of uo/umf. It was found that there was a linearlity between (Kbd)b and umf(db)-1/2 and that this proposed (Kbd)b was one of the catalytic fluidized bed design factor for the gas catalytic reaction.
