Polystyrene hydrogenation is an important post-polymerization process with good market prospects. However, the traditional powder catalysts are not suitable for industrialized process. In this paper, the macroporous ceramic foams (CFs) were prepared using synthetic template replica method. In order to obtain the ceramic foams with three-dimensional networks and good mechanical properties, a uniform design was carried out to optimize the composition of the slurry and calcining conditions, including the contents of H2O, binder, calcining temperature, heating rate, and calcining time. Effects of the rheological behavior of the slurry on the strength, porosity, and microstructure of the CFs were investigated in details. The obtained ceramic foam catalysts facilitated the separation of catalyst from solution and exhibited good catalytic activity.

Keywords:Catalytic reaction engineering; Ceramic foam; Polystyrene hydrogenation
