Abstract
A hydrodemetallization (HDM) catalyst includes an alumina and carbon extrudate support having a weight ratio of about 1:1 alumina to carbon and bimodal type pore size distribution, i.e., both meso-porosity and macro-porosity. The support can be impregnated with at least one hydrogenation active metal and, optionally, at least one promoter metal from the transition metals of Groups 6, 8, 9, and 10 of the Periodic Table. The hydrogenation active metal can be, for example, Mo, W, and Fe. The promoter metal can be, for example, Co, Ni, and Fe. The catalyst may further include ethylene diamine tetra acetic acid (EDTA).
