Estimating the term…
A composite oxide and a silicon capture agent, preparation methods therefor and the use thereof in hydrocarbon hydrogenation, and a method for treating a silicon-containing oil product are provided. The composite oxide has aluminum oxide and pseudo-boehmite. The pseudo-boehmite is loaded on the outer surface of the aluminum oxide, and the surface hydroxyl content of the composite oxide is 1,000-2,500 μmol/g. The silicon capture agent has aluminum oxide, pseudo-boehmite and an active component. The active component contains a group-VIB metal sulfide and a group-VIII metal sulfide; and the surface hydroxyl content of the silicon capture agent is 1,000-2,000 μmol/g. The composite oxide and the silicon capture agent provided have an improved surface hydroxyl content and an improved silicon capacity.
A composite oxide, is characterized in that the composite oxide comprises aluminum oxide and pseudo-boehmite, wherein the pseudo-boehmite is loaded on an outer surface of the aluminum oxide, and the surface hydroxyl content of the composite oxide is within a range of 1,000-2,500 μmol/g.
