▎ 摘 要
NOVELTY - Deep desulfurization of catalytic gasoline hydrogenation involves filtering raw material, placing to a buffer tank after being boosted by raw gas compressor and preheating furnace and pre-mixing with hydrogen to form a mixed gas to be preheated to 280 degrees C, and then exchanging with desulfurized output gas. The bed temperature in the hydrogenation reactor is controlled at 320 degrees C, and then the mixed gas is placed into the hydrogenation reactor. The hydrogenation catalyst is added under action of hydrogenation catalyst and olefin saturation reaction occurs at the same time, where the organic sulfur conversion reaction and the organic chlorine conversion reaction occur. The organic sulfur is converted into infinite sulfur, where the organic chlorine is converted into inorganic chlorine. USE - Method for catalytic gasoline hydrogenation deep desulfurization. ADVANTAGE - The method enables desulfurization of catalytic gasoline hydrogenation with improved denitrification effect. DETAILED DESCRIPTION - Deep desulfurization of catalytic gasoline hydrogenation involves filtering raw material, placing to a buffer tank after being boosted by raw gas compressor and preheating furnace and pre-mixing with hydrogen to form a mixed gas to be preheated to 280 degrees C, and then exchanging with desulfurized output gas. The bed temperature in the hydrogenation reactor is controlled at 320 degrees C, and then the mixed gas is placed into the hydrogenation reactor. The hydrogenation catalyst is added under action of hydrogenation catalyst and olefin saturation reaction occurs at the same time, where the organic sulfur conversion reaction and the organic chlorine conversion reaction occur. The organic sulfur is converted into infinite sulfur, where the organic chlorine is converted into inorganic chlorine. The zinc oxide desulfurization reactor is used to perform a desulfurization reaction between zinc oxide and hydrogen sulfide to remove sulfur from the original gas for obtaining refined oil with a sulfur content of 1 parts per million. The hydrogenation catalyst includes a shaped carrier and a mixture of active metal elements are filled on the shaped carrier, where the shaped carrier includes aluminum oxide, silicon oxide, magnesium oxide, titanium oxide, zirconium oxide, amorphous silicon aluminum, graphene and zeolite. The active metal element mixture comprises one or multiple elements of group VIII metal elements and group IV metal complexes containing phenoxyimine ligands.
