▎ 摘  要

NOVELTY - Mesoporous carbon composite material comprises 10-20 pts. wt. organic precursor, 40-60 pts. wt. inorganic template, 0-0.05 pts. wt. structure directing agent, 0-5 pts. wt. crosslinking agent, and 5-50 pts. wt. organic amine, where composite material is mesoporous carbon modified by liquid organic amine. USE - Mesoporous carbon composite material for removing hydrogen sulfide at room temperature (claimed) from industrial exhaust gas. ADVANTAGE - The composite material has large absorption, and fast hydrogen sulfide removal rate, and can be prepared in environmentally friendly, and simple manner. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for the following: (1) a method for preparing a mesoporous carbon composite material, which involves dissolving phenols in an aqueous solution of aldehydes to obtain an aqueous solution of organic precursors, dissolving the inorganic template and the cross-linking agent in water and ultrasonically mix, quickly adding the aqueous solution of the structure-directing agent to the above mixed solution, and continue to stir, adding the aqueous solution of the organic precursor to the above mixed solution, and stirring until the solution uniform mixing, sealing uniformly mixed solution and storing to obtain an organic polymer, and solid powder obtained after freeze-drying, carbonizing solid powder at a high temperature in an inert atmosphere, and after natural cooling to obtain mesoporous carbon after etching and washing with water, adding mesoporous carbon to the liquid organic amine solution for immersion, after drying to obtain mesoporous carbon composite material; and (2) use of mesoporous carbon composite material for removing hydrogen sulfide at room temperature by filling porous carbon composite material in the fixed bed reactor, controlling temperature of the fixed bed reactor to be constant, reaction pressure to normal pressure, passing hydrogen sulfide mixed gas through the fixed bed reactor at a certain space velocity, and utilizing gas chromatography with FPD detector to detect hydrogen sulfide gas concentration at the outlet of the reactor, when the hydrogen sulfide gas outlet concentration reaches 5% of the inlet concentration, the mesoporous carbon composite material is considered to be penetrated.
