CatGuard® RFC is a reticulated foam ceramic disk applied as a top bed grading layer in hydrotreaters and hydrocrackers to remove particulate contaminants in the feedstock to significantly reduce fouling and pressure drop buildup. It also provides excellent flow distribution as a top bed grading layer, reducing the risk of channeling in the catalyst bed downstream. The reticulated structure creates a tortuous flow path, which enhances filtration of particulates, and the high effective internal porosity creates a large particulate trapping capacity. The high external void space means that even when the RFC disks are completely filled with contaminants, the flow stream will simply bypass the disk with very little pressure drop. CatGuard® RFC is a cost-effective top bed grading solution for hydrotreaters and hydrocrackers.
