The development of a dip-coating method is described for the preparation of an active catalytic coating on a structured packing for the acylation of aromatics. The preparation was optimized by investigating various parameters in the dip-coating of both monolithic and wire gauze packings, such as the amount of zeolite, the amount of binder, the presence of a surfactant, the cell density of the monolith, and the packing material. BEA coatings strongly bound on ceramic monoliths and metallic wire gauze packings were prepared by dipping the structured packings in a BEA-containing, water-based slurry. The activity and selectivity of the slurry catalyst in the acylation of anisole with octanoic acid were well preserved by the coating procedure, while the structures can also easily be regenerated by calcination in air.
