System for selective catalytic hydrogenation. SELECTIVE HYDROGENATION and preparation and use

摘要

Abstract: the invention relates to a selective catalytic hydrogenation of selective hydrogenation catalyst system and preparation process and use. The catalyst system according to the invention, a carrier support material component and a catalyst component and a catalyst containing palladium Pd-containing catalyst component contributive contains bismuth. Bi containing cocatalyst component.And the catalyst according to the invention, by impregnating the impregnating article carrier solution containing palladium Pd-containing solution, a solution containing bismuth Bi-containing solution or / and solution a contributive One or more cocatalyst solution together or separately, and then carrying out drying drying Wtklys calcining.Improve the effectiveness of selective catalytic system according to the invention, in Alhdrjtalantqayyt compounds of Astylynyt Awlfynyt Bi acetylenic and diolefinic compounds Fytyarat hydrocarbon feed hydrocarbon f Eeds significantly but less oil is green green oil carbon deposit Walrasb carbon on the catalyst and increasing the useful life of service life production costs Llhfaz, with lower production costs.
