    Slurry Reactor an overview ScienceDirect Topics.Vassilis J. Inglezakis, Stavros G. Poulopoulos, in Adsorption, Ion Exchange and Catalysis, 2006 3.4.1 General. Slurry reactors are similar to fluidized-bed reactors in that a gas is passed through a reactor containing solid catalyst particles suspended in a fluid. In slurries, the catalyst is suspended in a liquid, whereas in fluidized beds, the suspending fluid is the reacting gas itself.
