成果简介	NOVELTY - Preparing demetallization nanocatalyst involves (a) impregnating 2-30 wt.% one transition metal on 60-85 wt.% an alumina extrudates to obtain a metal supported extrudates, (b) adding 1-20 wt.% one polymeric surfactant and 1-10 wt.% one structure directing agent to the metal supported extrudates, and (c) drying and calcining the metal supported extrudates to obtain a demetallization nanocatalyst, where the structure directing agent is a nitrogen-containing organic compound, and the polymeric surfactant contains one monomer unit derived from vinylpyrrolidone, wherein the w/w % is based on the total weight of the demetallization nanocatalyst. USE - Method for preparing demetallization nanocatalyst for residue upgradation, i.e., used for treating a hydrocarbon feed (claimed). ADVANTAGE - The prepared demetallization nanocatalyst are improved by addition of the surfactant. The surface area increases substantially due to the presence of micropores. The particle size deceases with inclusion of surfactant in the reaction system, which leads to increase in surface area along with the presence of micropores and shows improved demetallization (HDM) activity. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: A demetallization nanocatalyst comprises 60-85 wt.% alumina extrudates, 2-30 wt.% one transition metal and 1-20 wt.% one polymeric surfactant and 1-10 wt.% one structure directing agent. The structure directing agent is a nitrogen-containing organic compound, and the polymeric surfactant contains one monomer unit derived from vinylpyrrolidone. A process for demetallizing a hydrocarbon feed by treating the hydrocarbon feed with a demetallization nanocatalyst comprises 65-80 wt.% alumina extrudates, 4-25 wt.% transition metal, and 2-18 wt.% polymeric surfactant and 2-8 wt.% structure directing agent, which is a nitrogen-containing organic compound, and the polymeric surfactant contains monomer unit derived from vinylpyrrolidone. Use of a demetallization nanocatalyst for treating a hydrocarbon feed, comprises 60-85 wt.% alumina extrudates, 2-30 wt.% transition metal, and 1-20 wt.% polymeric surfactant and 1-10 wt.% structure directing agent, i.e., nitrogen-containing organic compound, and the polymeric surfactant contains monomer unit derived from vinylpyrrolidone.
