Abstract
A process for producing an unsupported molybdenum sulfide nanocatalyst comprising atomizing a molybdenum oxide solution to form a molybdenum oxide aerosol, pyrolyzing the molybdenum oxide aerosol with a laser beam to form the unsupported molybdenum-based nanocatalyst, and pre-sulfiding at least a portion of the unsupported molybdenum-based nanocatalyst to form an unsupported molybdenum sulfide nanocatalyst, wherein the unsupported molybdenum-based nanocatalyst, the unsupported molybdenum sulfide catalyst or both are in the form of nanoparticles with a diameter of 1-10 nm and in a distorted rutile crystalline structure. A method of selective deep hydrodesulfurization whereby a hydrocarbon feedstock having at least one sulfur-containing component and at least one hydrocarbon is contacted with the unsupported molybdenum sulfide nanocatalyst.
