Abstract
The present invention discloses a kind of preparation method of catalyst for cis-butenedioic anhydride liquid-phase hydrogenatin, includes the following steps: the SnCl of (1) using porous ceramics as carrier, using impregnation containing catechol2Solution is rinsed after dipping；(2) porous ceramics after being rinsed using step (1) dips palladium chloride solution, and the mixed solution of nickel sulfate, sodium dihydric hypophosphite and citric acid is impregnated after rinsing；(3) roast to the cellular ceramic substrate of the mixed solution of step (2) dipping nickel sulfate, sodium dihydric hypophosphite and citric acid the catalyst of obtained cis-butenedioic anhydride liquid-phase hydrogenatin.There is stronger active force between the catalyst activity component palladium and acid resistance carrier porous ceramics of this method preparation, active component palladium not easily runs off, and the stability of catalyst is largely increased.
Description
Technical field
The catalyst and preparation method thereof that the present invention relates to a kind of for cis-butenedioic anhydride liquid-phase hydrogenatin.
Background technique
With the breakthrough of butane oxidation maleic anhydride process, cis-butenedioic anhydride price declines, thus be hydrogenated by catalytic material of cis-butenedioic anhydride for
Succinic anhydride, succinic anhydride hydrolyzes again to be prepared succinic acid and attracts extensive attention, because succinic acid is a kind of common natural organic acids,
A kind of industrial important C4 compound, can be used as surfactant, detergent, green solvent, ion chelating agent, biology can
Degradable material, organic synthesis raw material, intermediate product or speciality chemical product be widely used in food, medicine, pesticide, dyestuff,
The fields such as fragrance, paint, plastics and material industry.And global succinic acid demand is continuously increased at present, so to maleic anhydride hydrogenation
The research that hydrolysis prepares succinic acid has practical significance.
Maleic anhydride hydrogenation technology is divided into two kinds at present: one is fusion method catalytic hydrogenation, another kind is solvent method liquid-phase hydrogenatin,
I.e. solvent dissolves cis-butenedioic anhydride, and catalyst system carries out liquid-phase hydrogenatin to cis-butenedioic anhydride solution.Solvent method liquid-phase hydrogenatin uses the Ith race and the VIIIth race
Element uses nickel for active component as hydrogenation active component in Chinese patent CN103769105A, and diatomite is urging for carrier
Agent, solvent method liquid-phase hydrogenatin obtain succinic anhydride product, but nickel, as active component, hydrogenation activity is not high, and catalyst
Active component nickel is lost serious.United States Patent (USP) US5952514 " technique for preparing succinic anhydride " uses the VIIIth race's element for catalysis
The active component of agent, and with the IVth race, group Ⅴ element alloy is mixed or formed to enhance the mechanical strength of catalyst.But
It is that the catalyst mentioned in this method contains one or more of Ni/Zr/Al/V/Si, catalyst service life can be generated
It influences, and has highly acid waste discharge in the subtractive process of succinic anhydride, have an adverse effect to environment.
In the prior art, precious metal palladium has good selectivity and higher conversion ratio maleic anhydride hydrogenation reaction.But
Maleic anhydride hydrogenation reaction system is acid system, and general acid nonfast carrier will lead to active component as carrier is lost together, resistance to
Acid vectors are such as: active carbon, ceramics are not because strong with palladium active force, the problem of also easily causing loss of active component.
Summary of the invention
