Shaofen Li, in Reaction Engineering, 2017. 9.4.1 Introduction. Trickle bed reactors are similar to fixed bed reactors for the catalytic gas–solid reactions discussed in the previous chapter—the major difference is that a single phase fluid flows in the latter whereas the fluid flows in two phases (gas and liquid) in the former. Obviously, the situation in the two-phase flow is more .
