Densicat®

Catalyst loading is a critical factor for maximizing catalyst performance. Drums, bins or bags are-used, depending on the refiner's choice and safety considerations. inimization of catalyst breakage and uniform catalyst distribution in the reactor are critical to the success of this operation. Sock loading may not maximize a reactor's capacity due to its tendency to create void spaces, and does not guarantee an homogeneous loading of the reactor which may give way to channeling and a non optimal use of the catalyst batch. Dense-loading techniques are very popular to achieve an improved catalyst orientation and uniform void spacing, and also to maximize bed density (high activity and bed stability). Among them, the most successful and reference for quality is Densicat®, the technology originally developed by TotalFinaElf and proposed by Petroval or its certified loading operators. The Densicat technology allows a predictable guaranteed maximum loading density, a perfectly homogenous loading, the highest speed and flexibility to accommodate many types of reactors, without any penalty due to higher pressure drops (Figure 6).

Advantages: Maximum catalyst density Catalyst bed homogeneity Horizontal orientation of grains High rate of loading No attrition
