A process for removing calcium from a hydrocarbon feed having at least 1 ppm oil-soluble calcium. The process employs a catalyst system, comprising catalyst particles, wherein a high volume percent of the catalyst particles are in the form of mesopores (less than 1000 Angstrom in diameter), low surface area, low hydrogenation activity, and th inclusion of Group VIII metals, in particular nickel, on a silica catalyst base.
